相对于诸如 Photoshop 或者 Gimp 这样的光栅(位图)图像编辑器，Inkscape 使用矢量格式保存其图像信息。矢量图像是一种分辨率无关的对实际形状和对象的描述，以便你能看到图像。一个光栅化引擎使用这些信息并决定如何在任意分辨率或者缩放级别上绘制每一条线段或者曲线。
请注意 Inkscape 也可以导出和显示位图。导入的位图将成为你的矢量图像中另一个对象，你可以像对待其它类型的对象那样处理它(移动、变形、剪裁等等)。
什么是“Scalable Vector Graphics(SVG)”？
Scalable Vector Graphics(SVG)是一款开放的，工业标准的，基于 XML 的矢量图像格式，由 W3C 开发。它正以迅猛的势头被业界广为接纳。今天，绝大部分矢量图像编辑器可以导入和导出 SVG，先进的浏览器(如 Firefox 和 Opera)可以无需使用插件直接现实它。对于 Internet Explorer，来自 Adobe 的SVG Viewer 插件可以显示 SVG。要了解更多，请阅读下面的#SVG 主题。
是的！尽管 Inkscape 还不具备领先的矢量图像编辑器的所有特性，最新的版本还是提供了大量基本的矢量图像编辑功能。在许多差别迥异的项目中(例如 Web 图像、技术图表、图标、创意图、徽标以及地图等领域)都有使用 Inkscape 的成功故事。举个例子，维基百科中成千上万的图片是使用 Inkscape 创建的，它还是 openclipart 中以及这里的内容中大多数也是使用 Inkscape 创建的。我们总是尝试让代码库对真正的用户有实用价值，我们相信开发人员和用户之间紧密的反馈循环将带来最好的结果。现在，你可以在你其他工具之外开始使用 Inkscape 了！
我们为 Linux、 Windows 2000/2003/XP(安装文件)和 OSX(dmg 包)提供二进制包。我们知道 Inkscape 已经成功的用于 FreeBSD 以及其它 Unix-like 的操作系统上。Windows 98/ME 已经不再被支持，至少以后是这样。
Inkscape was started as a fork of Sodipodi, in late 2003, by four Sodipodi developers: Bryce Harrington, MenTaLguY, Nathan Hurst, and Ted Gould. Our mission was creating a fully compliant Scalable Vector Graphics (SVG) drawing tool written in C++ with a new, more user friendly (Gnome HIG compliant) interface and an open, community-oriented development process. Within several months the project had produced several releases, demonstrating a sequence of significant new features and improvements to the codebase and quickly established Inkscape as a noteworthy Open Source project.
The name is made up of the two English words 'ink' and 'scape'. Ink is a common substance for drawings, and is used when the sketched work is ready to be permanently committed to paper, and thus evokes the idea that Inkscape is ready for production work. A scape is a view of a large number of objects, such as a landscape or ocean-scape, and thus alludes to the object-oriented nature of vector imagery.
Not yet, although many users use Inkscape for webpage mockups or generating web imagery such as banners, logos, icons, and more.
With the recent advances in SVG support in web browsers (such as Firefox or Opera), using SVG directly on the web becomes more of a possibility. For example, with Firefox 1.5 or better, you can open any Inkscape SVG document right in the browser, and Firefox will show it correctly. In theory, SVG and XHTML can be used together within the same document, so interested users or developers can explore this possibility further.
No, Inkscape does not support SVG animation yet. It is for static 2-D graphics. However you can export graphics from Inkscape to use in Flash or GIF animations. And since February 2006, Blender can import SVG data and extrude it to render 3D graphics.
会有 Inkscape 1.00 吗？它会是什么样子的呢？
Assuming development continues steadily, we will inevitably hit 1.00, but no particular date has been discussed yet.
Before going gold with any kind of 1.00 release, there would be a significant effort to tie down loose ends, a push for greater stability and smoothing off of rough edges. This would be a time consuming process and until it does happen Inkscape may be subject to substantial changes between releases.
为 Inkscape 做贡献
Grab the code and start hacking on whatever draws your attention. Send in a patch when you're happy with it and ready to share your efforts with others. We also need writers and translators for the user manual and interface internationalization (I18N) files.
We take contributions very seriously and follow the principle of "patch first, discuss later", so it is highly likely your efforts will appear in the development codebase swiftly. There are of course rules and standards that must be followed, but we try to keep them unsurprising and obvious.
Certainly! While there is certainly a lot of coding work to be done, there are also a lot of other non-programming tasks needed to make the project successful:
Bug wrangling and testing:
Identifying and characterizing bugs can help a HUGE amount by reducing the amount of development time required to fix them.
- Find and report bugs. This is a critical need for ensuring the quality of the code.
- Review and verify reported bugs. Sometimes the bug reports don't have enough info, or are hard to reproduce. Try seeing if the bug occurs for you too, and add details to the description.
- Performance Testing - Create SVG's that stress out Inkscape, and post them as test cases to the Inkscape bug tracker, with your time measurements.
- Compatibility Testing. Compare the rendering of SVG's in Inkscape with other apps like Batik and Cairo, and report differences found (to both projects).
- Bug prioritization. Bugs that are marked priority '5' are new bugs. Review them and set them to high/medium/low priority according to their severity. See Updating Tracker Items in wiki for details.
Helping fellow users
In addition to making a good drawing application, it's also extremely important to us to build a good community around it; you can help us achieve this goal directly, by helping other users. Above all, keep in mind that we want to maintain Inkscape's community as a nice, polite place so encourage good behavior through your own interactions with others in the group.
- Write tutorials. If something isn't already documented in a tutorial, write up a description of how to use it.
- Participate on inkscape-user@. Answer questions that pop up on the mailing list from other users. Also, share your tips and tricks, and demo new ways of using Inkscape for cool stuff.
- Create clipart. You can upload it to the openclipart.org project.
- Give Inkscape classes. Teach people local to you about using Inkscape. Or give presentations at local events, Linux group meetings, etc. about Inkscape (and other Open Source art tools).
Development (no coding needed)
- Translations. Information on how to create translations for the interface is available on the TranslationInformation page in Wiki.
- Design Icons and SVG themes. Create new icons for existing themes or start a new icon theme. Also see librsvg.sf.net
- Mockup new dialogs. Draw up ideas for improving or adding dialogs. These are handy to the UI developers for figuring out what to do.
- Improve packaging. Figure out how to make the package for your operating system or Linux distribution install and work better. See CreatingDists in Wiki.
- Add extensions. For file input/output, special features, etc. Inkscape is able to tie into external programs. Create new .inx files to hook these up for use in Inkscape. Also, if you're comfortable scripting in Perl, Python, etc. have a shot at improving the extensions, too!
- Add source code documentation The source code needs even the simplest documentation in some places, documenting functions will certainly help the next coder.
- Create templates. See the Inkscape share/templates directory.
- Work in Wiki. Wiki is a great place for gathering development info but always needs updating, copyediting, and elaboration.
- Plan future development. Review and help update the Roadmap in Wiki. Basically, talk with developers about what they're working on, planning to work on, or recently finished, and update the roadmap accordingly.
Spread the word - Inkscape Marketing and Evangelism
Increasing the size of the userbase is important. The network effects of more interested users means more potential contributors and hopefully people saying nice things about us, and giving Inkscape word of mouth advertising which we believe is important. All our users and developers serve as ambassadors for Inkscape and others will judge Inkscape based on how well we behave. It is important that we all be polite and friendly and make Inkscape a project people like using and enjoy working on, all other evangelism follows on naturally from there. Generally though for building the community we prefer quality over quantity so be careful not to go too overboard with evangelizing or the "hard sell". We want to work with other applications, rather than "killing" off other software and such comments are counter productive. We need to manage expectations. We want users to be pleasantly surprised by how much Inkscape does, not disappointed that it does not match other programs feature for feature. Inkscape should be thought of as providing artists another way to be creative which complements their existing skills and tools.
- Write Articles. Get articles published in various online (or even printed) magazines and blogs. Don't forget to include a link to Inkscape!
- Create Screenshots. Especially for new features.
- Create Examples. Examples are useful for showcasing different ways Inkscape can be used. Create some screenshots and text, and submit to the web wranglers (via the inkscape-devel mailing list) to add to the site.
- Work on the Website. Help on the website is ALWAYS appreciated. Knowledge of HTML is required; PHP know-how is helpful. Check out the website code from the Subversion (svn) repository and send patches, or request direct svn and shell access for doing on-going work.
- Give presentations. Give talks at expos, symposia, and other big events about Inkscape. Be sure to announce it on an inkscape mailing list so we can post it to the Inkscape website.
- Recruit more developers. Find people with an interest in doing coding, and encourage them to work on Inkscape.
Feel free to contribute your own banners or buttons for promoting Inkscape. The best ones will be linked here.
Inkscape prides itself on maintaining a friendly community, however we're all passionate and have different ideas, so sometimes discussions can get heated. However, when folks start taking firm positions on things it is easy for arguments to get out of hand and become unproductive, possibly even driving valuable contributors away from the project. So we place a high priority on striving to keep mailing list discussions civil.
Here are some tips for effectively communicating in the Inkscape community
1) Make your argument first and foremost without comparison. Really great features can stand on their own and are obviously great from the use cases users give. Most often comparisons won't strengthen your case. In fact they can often weaken your case because there is a built up resistance to this bandwagon sort of reasoning. Many people use Inkscape to escape from the software you want to compare it with. :-)
2) Don't assume that developers, users and industry professionals are mutually exclusive groups. Itch driven development means quite the opposite. Developers are users developing the software for their own uses. Some developers are industry professionals using Inkscape for their livelihood daily. This also means that arguments that start with generalizations about user wants and expectations have to struggle against the fact that the users are developing the software the way they want it.
3) Don't assume that resistance to your idea indicates rampant disregard for non-developer-users needs and wants. Many of the developers spend large amounts of time conversing with users in person, on IRC and on the mailing list. We know when issues are important because we can hear the consensus. As anecdotal evidence most of the features I have coded have been in direct response to the needs and requests of users who came with polite and persistent concerns.
Indeed, since Inkscape developers typically judge by user consensus, an effective way to prove a point is to show a pattern of demand for the change from a range of users, or to demonstrate how your change will satisfy a large number of user requests. (This isn't to say that what the unwashed masses ask for is always correct, but there are generally strong correlations.)
4) Street cred is earned, not demanded. :-) This is just a hard fact about community life. The project needs contributors to live and thrive, and everyone loves seeing new blood getting involved, and will bend over backwards to help. The more you involve yourself; the more you give of your own blood, sweat and tears, the more the community will respond to you. The great part is that simple contributions really do matter.
Remember Inkscape's slogan, "Patch first, discuss later." This is not just an aphorism; oftentimes the principles in an argument won't really understand all the factors until they can see the thing in practice, even if just a mockup or prototype. Presenting your ideas as a patch also bypasses the concern that others are going to have to put in the labor to implement the ideas.
5) Always remember we all share common goals. If nothing else, we all want to see Inkscape made better. When a discussion feels like it's starting to get hot, it's time for the arguers to seek areas of agreement, and focus on those.
Inkscape follows the convention used by CorelDraw, Xara and some other programs: instead of a separate "rotate" tool, you switch to Selector (arrow), click to select, and then click selected objects again. The handles around the object become rotation handles - drag them to rotate. You can also use the Tranasform dialog for precise rotation and the [, ] keys to rotate selection from the keyboard.
Text is not different from any other type of object in Inkscape. You can paint its fill and stroke with any color, as you would do with any object. Swatches palette, Fill and Stroke dialog, pasting style - all this works on texts exactly as it does on, for example, rectangles. Moreover, if in the Text tool you select part of a text by Shift+arrows or mouse drag, any color setting method will apply only to the selected part of the text.
When editing text on canvas, press Ctrl+U, then type the Unicode code point of the symbol you need. A preview of the symbol is shown in the statusbar. When done, press Enter. A list of Unicode codes can be found at unicode.org; for example, the integral sign character is "222b". You must have a font installed on your system that has this character; otherwise what you'll see is a placeholder rectangle.
When editing text on the Text tab of the Text and Font dialog, you can use any GTK input modes that your GTK installation supports. Consult GTK documentation for details.
When saving your work in eps format, we recommend to set the option "convert text to path" in the export dialog box, to preserve the symbol.
如何使用 Inkscape 绘制正弦曲线？
In 0.43, Inkscape includes an extension called Function Plotter (before that it was called Wavy). It can be used to create sine curves or any other function graphs. Other software, such as Xfig, KiG, or KSEG can also be used to create complex curves and then export to SVG for use in Inkscape.
Inkscape does not yet have a dedicated Measure tool. However, the Pen tool can be used in its stead. Switch to Pen (Shift+F6), click at one end of the segment you want to measure, and move the mouse (without clicking) to its other end. In the statusbar, you will see the distance and angle measurement. Then press Esc to cancel.
The angle is measured by default from 3 o'clock origin counterclockwise (the mathematical convention), but in Preferences you can switch this to using compass-like measurement (from 12 o'clock, clockwise).
Starting from 0.44 we also have the Measure Path extension that will measure the length of an arbitrary path.
Starting from 0.42, palettes are supported using the same file format as the GNU Image Manipulation Program (GIMP Colour Palettes, .gpl). The name used in Inkscape for the feature is "swatches". When selecting this terminology, we surveyed a number of different programs and found that both "palettes" and "swatches" were commonly found. Since the term palettes had been already been used in Inkscape to describe a particular type of dialog windows, the term "swatches" was adopted to describe this feature.
The extensions mechanism allows you to use external programs and scripts written in any language to augment Inkscape's capabilities. The tricky part is satisfying all of the dependencies of the external programs. For help satisfying dependencies of individual extensions check GettingExtensionsWorking. If you are specifically interested in Effects go straight to GettingEffectsWorking; if you're on Windows, consult GettingEffectsWorking/Windows, and for MacOSX, see the instructions at CompilingMacOsX#Enabling python effects.
如何打印教程？从 Inkscape 打印它们似乎不合适，而我又不想从屏幕上阅读教程。
All tutorials in all languages are available online in HTML at this page and can be easily printed from your browser.
在 Inkscape 中，我可以使用不同的设置来创建新的文档吗？
Yes. When you do File > New (Ctrl+N) or start a new Inkscape session, Inkscape loads the default template document which stores page format, grid and guide parameters, snapping and export settings, etc. It can even contain any pre-created objects. You can save any document as the default template by writing it to
~/.inkscape/templates/default.svg on Linux and
dir]/share/templates/default.svg on Windows. If you save it under any other name than
default.svg in the same folder, it will appear in the File > New submenu but will not load automatically unless chosen.
A stroke can be painted with a gradient, but that gradient will not bend with the stroke. It will remain linear or elliptic. If you meant something like this, then SVG can emulate such effects using SVG Filters which Inkscape does not yet support.
There are, however, a couple of workarounds. One is described here. The other is to use the Blend extension to create a blend between two curved paths painted with different colors or opacity levels; with enough intermediate steps, such a blend will look almost like an arbitrarily curved gradient.
The original object from which you're cloning must have its fill or stroke unset (not removed, but unset!) for this to work. Use the "?" button in the Fill&stroke dialog to unset fill, or use the "Unset" command in the right-click menu of the selected style indicator in the statusbar. If the original is a group, only some of the objects in the group may have unset fill, and only these objects will change colors in the tiling.
Note that per SVG rules, black color is opaque in a mask (i.e. it obscures the object under it); white color is transparent (the object shows through). What's more, the "no color" fill or full transparency is equivalent to "transparent black", i.e. (rather counterintuitively) also becomes opaque in a mask. So, if you want to make your object gradually masked out, create the masking gradient either from white to transparent, or from white to black. The detailed rules of SVG masks are defined in .
使用 Inkscape 导出的 PNG 有参差不齐的的边界/没有抗锯齿效果/有滑稽的背景。
This is a problem with whatever you use to view these PNG files, not with Inkscape. For example, Internet Explorer prior to version 7 cannot show PNG files with transparency properly. Use e.g. Firefox to view your PNGs. If you absolutely must support IE 6, you can't have transparent background in PNG; change it to opaque in Document Preferences and export the PNG file again.
If you want to open the exported PNG bitmaps in MS-Word, you will also have to change the alpha-opacity (in document-properties dialog) to full, and then export -- the result will be much better.
That's a known problem of our renderer (as well as many other renderers, for example Xara's). Antialiased display sometimes results in not-fully-opaque pixels along the boundary of two objects even if there's absolutely no gap between them. There are several ways to avoid this problem. If your boundary is horizontal or vertical, you can suppress antialiasing by pixel-snapping (see next question). Often, you can just union the two shapes so they become one and the seam disappears. If this is not possible, just add a small overlap to the abutting shapes. If this isn't possible either (for example, due to transparency of these objects), sometimes blurring can help: in Inkscape 0.45+, you can group the two objects and slightly blur the group to make the seam disappear.
With the current renderer, it is not possible to completely get rid of antialiasing. However, it is possible to partially suppress it on export. Usually, antialiasing is unwelcome in horizontal and vertical lines which become "blurred". To work around this, make sure your horizontal/vertical edges are snapped on the pixel grid, and all strokes are a whole number of pixels wide. Then, export bitmap at the default 90dpi so that 1 px unit corresponds to 1 bitmap pixel. In the resulting bitmap, snapped color boundaries will be perfectly crisp.
Yes, Inkscape has a powerful command line interface and can be used in scripts for a variety of tasks, such as exporting and format conversions. For details, refer to the manual page (online, or via the Help > Command line options command, or by
man inkscape on Unix).
我在 Windows 中，似乎命令行参数不能工作！
Actually, things like exporting or converting to plain SVG do work, they just do not output anything to the console. This is because Inkscape on Windows is a GUI application and is not allowed to have any console output. This means that query options (such as
--query-x) will not work at all. But this can be fixed if you recompile Inkscape as a console application. See this page for general Windows compilation instructions; edit the file Makefile.mingw.common in the source tree's root directory and replace
-lgc -mwindows -lws2_32 -lintl
-lgc -mconsole -lws2_32 -lintl -lgdi32 -lcomdlg32
then recompile. This will give you an inkscape.exe which works exactly as it does on Linux with regard to command line parameters and console output. If you regularly use Inkscape's command line interface on Windows, please send a message to the inkscape-devel list and we may consider providing such a console executable in our official Inkscape Windows builds.
如何让 Alt+click 和 Alt+drag 能在 Linux 下工作？
Alt+click and Alt+drag are very useful Inkscape shortcuts ("select under" and "move selected" in Selector, "node sculpting" in Node tool). However, on Linux Alt+click and Alt+drag are often reserved by the window manager for manipulating the windows. You need to disable this function in your window manager so it becomes usable in Inkscape.
For example, in KDE this is done in Control Center > Desktop > Window Behavior > Window Actions.
Please read xfwm4.html
Go to System > Preferences > Windows. You are presented with three options to move windows around: "Alt", "Ctrl" or "Super" (Windows logo key). Choose "Super".
在 Linux 中使用非拉丁字符的文件名出现问题，救命！
If your locale charset is not UTF-8, then you need to have this environment variable set:
$ G_BROKEN_FILENAMES=1 $ export G_BROKEN_FILENAMES
This is necessary for Glib filename conversion from the locale charset to UTF-8 (used in SVG) and back to work. Read more details.
如何让 Alt+click 和 Alt+drag 能在 Mac OS X 下工作？
If you find yourself unable to use Inkscape functions that require the ALT key (such as Node Sculpting) you will need to turn off the "Emulate three button mouse" under the Input Preferences for X11.
我工作在使用 xxx 操作系统的机器上，默认的语言是 yyy，但是我想 Inkscpae 的菜单使用 zzz(通常是英语)，我该如何设置？
- Fist type locale -a in the console
- to find out, which locale settings are supported on your system and how they were written.
- export LANGUAGE="C" in the commandline switches to the default language (English).
- export LANGUAGE="de_DE.utf-8" changes the language to german. This command works only temporary. After a system restart the original locale is active. The
- used locale has to be installed with inkscape on your computer (else, Inkscape falls back to the default language).
- The official Mac OS X way is to provide
.lprojfiles which enables applications to pick up the
- preferred language
- from the System Preferences dialog; however, this is probably some considerable
- way into the future. It might be possible to set up a scheme involving langauge :: packs, otherwise the linux methods may work.
- The official Mac OS X way is to provide
- Easy way
- Create a batch file in your inkscape installation directory. Call it inkscape.bat.
- Add the lines (replace with your LANG setting)
- @set LANG=de_DE
- @start inkscape.exe
- Save and double-click to use it.
- Using System Settings: Either delete the yyy language files, or change the language by setting the LANGUAGE environment variable.
- A. Deleting the yyy language files
- Beware, this change the behaviour for all inkscape users on this machine
- 1. Locate the installation directory.
- 2. Enter the Inkscape\locale directory
- 3. Locate the directory with the two letter locale you don't want to use.
- 4. Rename (or remove) this directory to something like disable_de or x_es
- 5. Restart inkscape and the default English (en) locale will be used.
- B. Setting the LANGUAGE environment variable
- Probably this only works when you have administrator (or poweruser?) rights on your pc.
- 1. Go to the control panel, doubleclick on "System".
- 2. Select the "Advanced" tab, and press the "Environment variables" button.
- 3. You can either add the 'LANGUAGE' variable to the current user or to all users (system variables). Press the 'New' button and enter 'LANGUAGE' as the variable name, and 'C' as value if you want to select the default language (English) or e.g. 'de' if you want to set the language to german.
- Easy way
我在我的 Windows 中安装了新的字体，但是 Inkscpae 没有找到它。
This was a bug in versions of Inkscape up to 0.43, caused by using an obsolete font cache. This cache is stored in the file called
.fonts.cache-1. This file may be in your Windows folder, or in your Temp folder, or in "My documents" folder, or in the folder listed in the $HOME environment variable. Use file search by name to locate this file. Then simply delete this file and restart Inkscape; now it will see the new fonts.
我已经在 OS X 10.4.x 上安装了 Inkscape，但是当我运行它时没有任何反应。
Under OS X 10.4.x, even on very fast machines, Inkscape versions prior to 0.44 could take a long time to start the very first time they were run. This was due to a fontconfig cache workaround that wasn't properly implemented by the launcher code. The problem has been fixed in 0.44 (though not in the prereleases 0-3).
在 Linux 上，Inkscape 崩溃了，返回“invalid pointer”信息
If your Inkscape crashes on start with the error message that looks like
*** glibc detected *** free(): invalid pointer: 0x086143b0 ***
this is caused by GCC versions incompatibility which affects C++ applications. Your Inkscape is compiled by a different version of GCC than the C++ libraries it uses. Recompile either Inkscape itself or its C++ libraries (libstdc++, libsigc++, libglibmm and libgtkmm) with the single GCC version and the problem will go away.
Inkscape 的 SVG 文档是有效的 SVG 格式吗？
Yes. Inkscape does not yet support all features of SVG, but all files it generates are valid SVG (with the partial and temporary exception of flowed text, see below). All standard-conformant SVG renderers show them the same as in Inkscape. If they do not, it's a bug. If this bug is in Inkscape, we will fix it (especially if you help us by reporting it!).
When flowed text support was added to Inkscape, it was conformant to the then-current unfinished draft of SVG 1.2 specification (and was always described as an experimental feature). Unfortunately, in further SVG 1.2 drafts, the W3C decided to change the way this feature is specified. Currently SVG 1.2 is still not finished, and as a result, very few SVG renderers currently implement either the old or the new syntax of SVG 1.2 flowed text. So, technically, Inkscape SVG files that use flowed text are not valid SVG 1.1, and usually cause problems (errors or just black boxes with no text).
However, due to the utility of this much-requested feature, we decided to leave it available to users. When the final SVG 1.2 specification is published, we will change our flowed text implementation to be fully conformant to it, and will provide a way to migrate the older flowed text objects to the new format.
Until that is done, however, you should not use flowed text in documents that you intend to use outside of Inkscape. Flowed text is created by clicking and dragging in the Text tool, while simple click creates plain SVG 1.1 text; so, if you don't really need the flowing aspect, just use click to position text cursor instead of dragging to create a frame. If however you really need flowed text, you will have to convert it to regular (non-flowed) text by the "Convert to text" command in the Text menu. This command fully preserves the appearance and formatting of your flowed text but makes it non-flowed and SVG 1.1-compliant.
什么？那么，是不是当保存文档时保存的是“Insscape SVG”而不是“Plain SVG”？
Inkscape SVG files use the Inkscape namespace to store some extra information used by the program. Other SVG programs will not understand these extensions, but this is OK because the extensions only affect how the document is edited, not how it looks. Extensions must not cause any rendering problems in SVG-compliant renderers. However, some non-compliant renderers may have trouble with the presence of the extensions, or you may want to save some space by dropping the Inkscape information (if you're not planning to edit the file in Inkscape again). This is what the "Plain SVG" option is provided for.
Inkscape 实现了哪些 SVG 特性？
The main parts of SVG that Inkscape does not support yet are filters (except Gaussian blur which is supported starting from 0.45), animation, and SVG fonts. The rest mostly works, though of course there are bugs that we're always fixing. For a comparison of Inkscape and other open source SVG tools on the W3C SVG test suite, look here.
我手工创建了 SVG。当我用 Inkscape 打开它在保存的时候，会不会所有东西都混到一块了？
Inkscape strives to avoid changing the SVG just because it does not recognize some of the SVG elements, however it *does* make changes:
- All objects will get unique "id" attributes. If already existing and unique, they will be preserved, otherwise one will be derived from node name.
- Some sodipodi: and inkscape: namespaced metadata will be added to the beginning of document.
- If you edit a gradient, that gradient will be broken up into 2 linked gradients - one defining color vector, another one position.
- Changing any style property forces reconstructing of the whole 'style' attribute, which means CSS (not XML) comments will be lost and formatting of CSS may change.
- The formatting style of the SVG file will be changed to follow the style hardcoded into Inkscape.
There is ongoing work to allow Inkscape to better preserve hand-created SVG markup but it is a very difficult task requiring a lot of infrastructure work and will happen very gradually - but help is always appreciated.
Inkscape 和 X 渲染器显示我的 SVG 看起来不同。该怎么办？
That depends on X. We accept Batik and Adobe SVG plugin as authoritative SVG renderers because they are backed by some of the the authors of the SVG standard and really care about compliance. This may not be true for other renderers. So if you are having a problem with some renderer, please try the same file with either Batik or Adobe, or better yet, with both (they are free and cross-platform). If you still see a discrepancy with Inkscape rendering, we want to look into it. Please submit a bug; don't forget to attach a sample of the problem file to the bug report, and ideally include screenshots too.
为什么从 Sodipodi 分离出来？
Inkscape started as a code fork of Sodipodi. The main reasons were differences in objectives and in development approach. Inkscape's objective is to be a fully compliant SVG editor, whereas for Sodipodi SVG is more a means-to-an-end of being a vector illustration tool. Inkscape's development approach emphasizes open developer access to the codebase, as well as using and contributing back to 3rd party libraries and standards such as HIG, CSS, etc. in preference to custom solutions. Reusing existing shared solutions helps developer to focus on the core work of Inkscape.
For background, it may also be worth reviewing Lauris' Sodipodi direction post from Oct 2003, and his thoughts on SVG, licensing, and the value of splitting the project into two independent branches.
Inkscape 和 Dia 的区别是什么？
Dia is for technical diagrams like database charts, class diagrams, etc., whereas Inkscape is for vector drawing such as logos, posters, scalable icons, etc.
SVG is a useful format for creating diagrams, though, so we hope as Inkscape grows as a fully-featured SVG editor, it will also be useful for making attractive diagrams too. Several of us hope Inkscape will become a useful technical drawing tool and work on features with that goal in mind. However, Dia provides a number of useful capabilities such as support for UML, autogeneration of diagrams, etc. that are well beyond the scope of a general SVG editor. Ideally both Inkscape and Dia can share various bits of code infrastructure and third party libraries.
它有意于替换 Flash 吗？
While SVG is often identified as a "Flash replacement", SVG has a huge range of other uses outside that of vector animation. Replacing Flash is not one of Inkscape's primary intents. If SVG can replace Flash, and Inkscape can help, that's great, but there's a lot more to SVG than web animation that is worth exploring. (See also SMIL)
Inkscape 是 GIMP 或者 Photoshop 的替代品吗？
In most cases, no. They're used for two very different things. Inkscape is used for creating vector drawings, such as laying out a poster or creating a fancy logo, whereas bitmap editors are for working on raster images, such as touching up a photograph. In many projects, you would need to use both Inkscape and a bitmap editor (such as GIMP), for example, to add bitmap effects to an image exported from Inkscape.
However, currently bitmap editors are often used for common tasks they are not well equipped for, such as creating web page layouts, logos, or technical line art. In most cases, this is because users are not aware of the power (or even the existence) of the modern vector editors. Inkscape wants to amend this situation, and to raise a vector editor to the status of an essential desktop tool for everyone, rather than an exotic specialized tool that only professionals use.
Inkscape 会成为 Gnome-Office 的一部分吗？
Inkscape will need to mature a bit further before this can be considered. Specifically, better support for embedding (Bonobo) is needed, and the Gnome-Print subsystem needs to be tested more thoroughly (help very much appreciated here). If you can compile a recent version of Inkscape and help us with testing it would be very useful.
Inkscape natively supports opening only SVG and SVGZ (gzipped SVG) formats.
Inkscape can natively save as SVG, SVGZ, Postscript/EPS/EPSi, Adobe Illustrator (*.ai), LaTeX (*.tex), and POVRay (*.pov).
With the help of extensions, Inkscape can open/save as PDF, EPS, AI, Dia, Sketch and some others.
Inkscape can natively import most raster formats (JPG, PNG, GIF, etc.) as bitmap images, but it can only export PNG bitmaps.
See FileTypes for discussion about file formats that people would like to see supported, and third-party tools that can be used to convert files to or from SVG.
如何使用 Inkscape 处理 *.cdr (Corel Draw 矢量绘图文件)？我的图片在 *.cdr 文件中而我打算以 *.SVG 继续工作。
- Open CDR file Corel Draw. Save it as CGM file. It will save only vector graphics. It will not save bitmap graphics.
- Open CGM file in OpenOffice Impress. Copy to Open Office Draw and insert original JPG or another bitmap graphics. Save file as ODG And you can continue in Open Office Draw program.)
- Select all (CTRL+A)
- Export as SVG.
- Open SVG file in Inkscape and correct mistakes if they appear.
我从 Adobe Illustrator 导出了一个 SVG 文件，使用 Inkscape 编辑后再导入 AI，但是我的修改不见了！
That's because Adobe cheats. It creates a valid SVG, but apart from the SVG code it also writes to the file, in encoded binary form, the entire AI-format source file of the image. Inkscape, of course, edits the SVG part of the image and leaves the encoded binary untouched. But when you import the SVG file back to AI, it completely disregards the SVG code with its edits and reads directly from the encoded AI binary. Therefore, any SVG changes are lost. To work around it, in Inkscape open the XML Editor and remove the non-SVG elements (everything not with the svg: prefix in its name).
Inkscape wants to be a complete SVG-compliant vector graphics editor. Apart from standards compliance, our primary goals are stability, performance, state of the art vector graphics features, and an efficient and innovative user interface.
The codebase Inkscape inherited from Sodipodi was C/Gtk based. There is an ongoing effort to convert the codebase to C++/Gtkmm. The ultimate goal is to simplify the code and make it more maintainable. We invite you to join us. Just don't mention Qt. :)
What is your position on code sharing with other projects?
Yes, sharing of code libraries with other projects is highly desirable, provided the right conditions exist. A good candidate for a library will be mature, widely distributed, well documented, and actively maintained. It should not introduce massive dependency problems for end-users and should be stable, powerful, and lightweight. It should strive to do one thing, and do it well. Libraries that don't meet all the criteria will be considered on a case-by-case basis.
如何创建 Inkscpae 扩展？
You don't need to know much, if anything, about Inkscape internals to create a useful extension. Aaron Spike, the author of most Python extensions that come with Inkscape, wrote a helpful web page (including a series of tutorials) on creating extensions in Python (Perl and Ruby are also supported).
You can start with the Doxygen documentation. There you can find not only the usual Doxygen stuff but also different categorized views into the inkscape source.
In the Documentation section of the Inkscape website you can find some high-level diagrams and links to other documentation that's been produced such as the man page. Historically, this codebase has not been kept well documented so expect to find many areas where the only recourse is to work through the code itself. However, we place importance on working to change this, and to flesh out the documentation further as we go.
Some developers have found that testing patches is a good way to quickly get exposure to the code, as you see how other developers have approached making changes to the codebase. Other developers like to pick an interesting feature request (or perhaps a feature wish of their own) and focus on figuring out how to implement it. Occasionally we also have large scale grunt-work type changes that need to be applied to the codebase, and these can be easy ways to provide significant contributions with very little experience.
Getting beyond initial exposure, to the next stage of understanding of the codebase, is challenging due to the lack of documentation, however with some determination it can be done. Some developers find that fixing a crash bug by tracing execution through the various subsystems, brings good insights into program flow. Sometimes it is educational to start from an interesting dialog box and tracing function calls in the code. Or perhaps to start with the SVG file loader and follow the flow into and through the parser. Other developers have found that writing inline comments into the code files to be highly useful in gaining understanding of a particular area, with the fringe benefit of making that bit of code easy for future developers to pick up, too.
Once you feel far enough up the learning curve, implementing features will firm up your experience and understanding of the codebase. Be certain to also write test cases and documentation, as this will be of great help to future developers and thus ensure the longevity of the codebase.
The latest statistics are available at this page. The code is somewhat modular, but less so than we would like. If you're interested in some specific part of the codebase, feel free to ask developers.
Currently we use our own renderer called livarot. We plan to migrate to Cairo when it is mature enough.
Most developers work on Linux. However it is also possible to compile Inkscape on Windows; this page provides detailed instructions for this as well as for cross-compiling Windows binaries on Linux.
在 Linux 下通过 Subversion 下载代码的命令是？
Generic directions are under the Subversion link on the inkscape sourceforge page. Note, however, that the command given on the sourceforge page will check out all modules of the Inkscape project and all branches of those modules.
- To only check out the latest copy of the main branch (also called "trunk") of the Inkscape program, do:
svn checkout https://svn.sourceforge.net/svnroot/inkscape/inkscape/trunk/
- To only check out the trunk of another Inkscape module, do:
svn checkout https://svn.sourceforge.net/svnroot/inkscape/MODULE_NAME/trunk/where
MODULE_NAMEis the name of the module you want to check out. Other modules you can check out include:
experimental, our development "scratchpad" for working up prototypes;
inkscape_web, which holds our website files; and
inkscape_project, which holds config files and other project-level things. You can use our Subversion viewer to get the names of available modules.
- To only check out a branch of some Inkscape module, do:
svn checkout https://svn.sourceforge.net/svnroot/inkscape/MODULE_NAME/branches/BRANCH_NAME/where
MODULE_NAMEis the name of the module you want to check out, and
BRANCH_NAMEis the name of the branch that you are interested in. You can use our Subversion viewer to get the names of available modules and branches.
These commands will download the requested module into a directory named either
BRANCH_NAME, depending on whether you chose to check out the trunk or a branch.
- If you'd like to later test out a different branch of any of Inkscape's modules, you can do that by running
svn switch https://svn.sourceforge.net/svnroot/inkscape/MODULE_NAME/branches/BRANCH_NAME
in your working copy, where
MODULE_NAME is the name of the module you are working in, and
BRANCH_NAME is the name of the branch that you want to switch to.
- You can do something similar for tagged branches:
svn switch https://svn.sourceforge.net/svnroot/inkscape/MODULE_NAME/tags/BRANCH_NAME
Note that Subversion supports the ability to move individual subdirectories of a working copy of a module to different branches of that module, so if you want to switch an entire working copy to a different branch, run
svn switch in the root directory of the working copy.
Many developers become involved because they wish to "scratch an itch", so of course if they wish to work on a particular feature, then by definition that one will receive implementational attention. This is the primary mechanism by which features get implemented.
Inkscape also strives to take user requests for features seriously, especially if they're easy to do or mesh with what one of the existing developers already wants to do, or if the user has helped the project in other ways.
If you have a feature that you'd really like to see implemented, but others aren't working on, the right thing to do is delve into the code and develop it yourself. We put great importance on keeping the development process open and straightforward with exactly this in mind.
Understandably, many users are accustomed to other programs (such as Illustrator, the GIMP, etc.) and would prefer Inkscape to follow them in design. Inkscape developers are constantly examining other projects and on the look for better interface ideas. A large motivation is to make the application follow the GNOME Human Interface Guidelines, which has a number of rules in how the interface is made. The Inkscape developers also seek advice and ideas from other GUI app designers, such as the GIMP crew, AbiWord, and Gnumeric; they've been at it longer and we view them as an excellent source of battle tested experience.
But please understand that the Inkscape interface will, at the end of the day, be the "Inkscape interface". We will strive to find our own balance of compatibility with common drawing programs, wishes of our userbase, good workflow, creativity of our developers, and compliance with UI guidelines. It's unlikely that this balance will meet every user's wish, or achieve 100% compliance with the various platform specific Interface Guidelines, or include every developer's idea, and if it did it probably wouldn't be as good. ;-)
Usually when we discuss interface look and feel, we arrive at the conclusion that, really, it should be configurable so that each user can flip a few switches and get an app that is most cozy to them. However, flexibility should not be used as an excuse not to make tough decisions when they are called for.
