General

¿Qué es Inkscape?

Inkscape es un editor de gráficos vectoriales de fuente abierta (open source) similar a Adobe Illustrator, Corel Draw, Freehand, o Xara X. Lo que diferencia a Inkscape es que utiliza Scalable Vector Graphics (SVG), un estándar abierto del W3C basado en XML, como formato nativo.

¿Qué son los gráficos vectoriales?

A diferencia de los editores de gráficos rasterizados (mapas de bits), como Photoshop o Gimp, Inkscape almacena sus gráficos en formato vectorial. Los gráficos vectoriales describen las formas y objetos reales que ve en la imagen, independientemente de la resolución de la misma. Un motor de rasterización utiliza esta información para determinar cómo dibujar cada línea y curva en cualquier resolución o nivel de acercamiento.

Esto contrasta con los gráficos rasterizados, que siempre están atados a una resolución específica y almacenan la imagen como una grilla de píxeles.

Los gráficos vectoriales son un complemento a los gráficos rasterizados, más que una alternativa. Cada uno tiene su propósito y son útiles para distintas cosas. Los gráficos rasterizados suelen ser mejores para fotografías y algunos dibujos artísticos, mientras que los vectoriales son más aptos para composiciones de diseño, logotipos, imágenes con texto, ilustraciones técnicas, etc.

Sin embargo Inkscape también puede importar y mostrar gráficos rasterizados. Una vez importado, éste se convierte en otro objeto dentro del gráfico vectorial y se puede hacer con él todo lo que es posible con otros tipos de objetos (moverlo, transformarlo, recortarlo, etc).

¿Qué significa SVG 'Scalable Vector Graphics'?

Gráficos Vectoriales Escalables (SVG) es un formato abierto y estándar basado en XML para gráficos vectoriales, desarrollado por el W3C. Su aceptación está creciendo rápidamente. La mayoría de los editores vectoriales actuales pueden importar y exportar SVG y los navegadores modernos (como Firefox y Opera) pueden mostrarlo directamente sin la necesidad de plugins. (Para el Internet Explorer, hay un plugin para visualizar SVG hecho por Adobe). Para más información vea #SVG topics, abajo.

¿Inkscape está listo para ser usado por usuarios comunes?

¡Sí! Aunque Inkscape no tiene todas las características que poseen los editores más avanzados, las últimas versiones brindan gran parte de las funciones de edición vectorial básicas. Muchas personas utilizan Inkscape con éxito para diversos proyectos (gráficos web, diagramas técnicos, íconos, arte creativo, logotipos, mapas). Vea ejemplos en las galerías. Siempre tratamos de mantener el código usable, ya que pensamos que un ciclo de iteración ajustado entre usuarios y desarrolladores dará los mejores resultados. Puede empezar a utilizar Inkscape junto a sus otras herramientas ¡ahora mismo!

¿En qué plataformas funciona Inkscape?

Proveemos paquetes binarios para Linux, Windows 2000/2003/XP (autoinstalable completo), y Mac OS X (paquete dmg). Sabemos que Inkscape también funciona en FreeBSD y otros sistemas operativos similares a Unix. No hay versiones para Windows 98/ME, aunque no descartamos realizarlas más adelante.

¿Cómo comenzó Inkscape?

Inkscape comenzó como una bifurcación de Sodipodi en 2003, por cuatro desarrolladores del mismo: Bryce Harrington, MenTaLguY, Nathan Hurst, and Ted Gould. Nuestra misión era crear una herramienta de dibujo completamente compatible con Gráficos Vectoriales Escalables (SVG) escrita en C++, con una nueva interfaz más amigable (compatible con Gnome HIG) y un proceso de desarrollo abierto y orientado a la comunidad. Al cabo de varios meses el proyecto había producido varios lanzamientos (releases), mostrando sucesivas mejoras significativas en el código, nuevas características y estableciéndose rápidamente como un proyecto de código abierto notable.

¿Qué significa 'Inkscape'?

El nombre está compuesto por las dos palabras inglesas ink (tinta) y scape (paisaje o vista). La tinta es una sustancia común para dibujos, y se utiliza cuando el trabajo bocetado está listo para ser trasladado en forma permanente al papel; por lo tanto evoca la idea de que Inkscape está listo para trabajo de producción. Y scape es una vista de una gran cantidad de objetos, como un paisaje o vista al mar, y por lo tanto alude a la naturaleza orientada a objetos propia de las imágenes vectoriales.

¿Puedo crear páginas web con esto?

Aun no. Sin embargo muchos usuarios utilizan Inkscape para plantear las páginas web o para generar las imágenes utilizadas en las mismas, como banners, logotipos, íconos, y otros.

Con los recientes avances en soporte SVG en los navegadores web (como Firefox u Opera), usar SVG directamente en la web se convierte en más que una posibilidad. Por ejemplo, con Firefox 1.5 o mejor puede abrir cualquier documento SVG de Inkscape y Firefox lo mostrará correctamente. En teoría, se puede utilizar SVG y XHTML en el mismo documento, por lo que los usuarios y desarrolladores que estén interesados pueden explorar aun más esta posibilidad.

¿Puedo crear animaciones con esto?

No. Inkscape no soporta animación SVG aun; es para gráficos estáticos en 2 dimensiones. Sin embargo se pueden exportar gráficos de Inkscape para usar en animaciones Flash o GIF. Y desde Febrero de 2006, Blender puede importar información SVG y proyectarla para crear gráficos 3D.

¿Habrá una versión 1.00 de Inkscape? ¿Cuándo será?

Asumiendo que el desarrollo continúe estable, inevitablemente llegaremos a la versión 1.00, pero no hemos discutido ninguna fecha aun.

Antes de hacer cualquier versión definitiva habrá un esfuerzo considerable para atar cabos sueltos, conseguir mejor estabilidad y limar asperezas. Esto demandará tiempo y hasta que suceda Inkscape puede sufrir cambios considerables entre un lanzamiento y otro.

Contribuyendo a Inkscape

¿Cómo puedo ayudar?

Toma el código y comienza a trabajar en lo que te atraiga. Envía un parche cuando estés satisfecho y comparte tus esfuerzos con otros. También necesitamos escritores y traductores para el manual de usuarios y los archivos de internacionalización de la interfaz (I18N).

Tomamos muy seriamente las contribuciones y seguimos el principio de "arreglar primero, discutir después", por lo que es muy probable que tus cambios aparezcan rápidamente en el código. Por supuesto hay reglas y estándares que deben ser respetados, pero tratamos de que sean obvios y lógicos.

¿Hay formas de colaborar que no sean programar?

¡Ciertamente! Aunque hay mucho trabajo de programación pendiente, también hay otras tareas necesarias para hacer de este proyecto un éxito:

Identificar errores y probar:

Identificar y caracterizar errores puede ayudar ENORMEMENTE al reducir el tiempo de desarrollo necesario para arreglarlos.

  • Encontrar y reportar errores. Esta es una necesidad crítica para asegurar la calidad del código.
  • Revisar y verificar errores reportados. A veces los reportes de errores no tienen suficiente información, o son muy difíciles de reproducir. Intenta ver si el error te ocurre a ti también, y agrega detalles a la descripción.
  • Prueba de rendimiento - Crea gráficos SVG que exigan a Inkscape y envíalos como casos de prueba para el seguidor de errores de Inkscape, con tus medidas de tiempo.
  • Compatibilidad y Prueba. Compara la representación de gráficos SVG en Inkscape con la de otras aplicaciones como Batik y Cairo, y reporta las diferencias encontradas (a ambos proyectos).
  • Priorización de errores. Los errores que están marcados con prioridad '5' son errores nuevos. Revísalos y fija la prioridad a alta/mediana/baja, según su severidad. Ver Actualizando items de seguimiento en la wiki para más detalles.

Ayudando a otros usuarios

Además de lograr una buena herramienta de dibujo, para nosotros es extremadamente importante construir una buena comunidad alrededor; tú puedes ayudarnos a conseguir esto directamente, ayudando a otros usuarios. Queremos mantener un buen ambiente en la comunidad de Inkscape, así que te animamos a que lo fomentes siendo amable con el resto de usuarios.

  • Escribe tutoriales. Si hay algo que aún no ha sido documentado en un tutorial, escribe una descripción de cómo usarlo.
  • Participa en inkscape-user@. Responde a las preguntas que otros usuarios envían a la lista de correo. También, comparte tus trucos y muestra nuevas formas de usar Inkscape.
  • Crea cliparts. Puedes colaborar con el proyecto openclipart.org.
  • Imparte clases de Inkscape. Enseña a gente de tu entorno a usar Inkscape. Realiza presentaciones en eventos locales, reuniones de usuarios de Linux, etcétera... sobre Inkscape (y otras herramientas artísticas libres).

Desarrollo (sin necesidad de programación)

  • Traducciones. Hay información sobre cómo crear traducciones de las interfaces en TranslationInformation.
  • Diseño de iconos y temas SVG. Crea nuevos iconos para los temas existentes o crea un nuevo tema de iconos. Consulta también librsvg.sf.net
  • Bosqueja nuevos diálogos. Dibuja ideas para mejorar o añadir cajas de diálogos. Estos bocetos son útiles para que los desarrolladores de la interfaz de usuario introduzcan mejoras.
  • Mejora los paquetes. Piensa cómo preparar y mejorar los paquetes para tu sistema operativo o tu distribución Linux. Consulta CreatingDists en este wiki.
  • Añade extensiones. Inkscape puede extenderse para añadir prestaciones, como por ejemplo abrir y guardar más tipos de documento. Crea archivos .inx para usarlos en Inkscape. También, si te sientes cómodo codificando en Perl, Python... puedes mejorar las extensiones.
  • Añade documentación del código fuente El código fuente necesita estar bien documentado para ayudar a los diferentes programadores.
  • Crea plantillas. Consulta la carpeta share/templates en Inkscape.
  • Trabaja en el Wiki. El Wiki es un buen lugar para reunir información del desarrollo pero siempre necesita actualizaciones, ediciones y elaboración.
  • Actualiza el mapa de ruta. Revisa y ayuda a actualizar el Roadmap en el Wiki. Básicamente, habla con los desarrolladores sobre qué están haciendo, qué planes tienen, qué acaban de terminar, y actualiza la hoja de ruta con esa información.

Difunde la palabra - Mercadotecnia y evangelización de Inkscape

Aumentar el número de usuarios es importante. Cuantos más usuarios interesados haya, habrá potencialmente más contribuyentes y gente diciendo cosas buenas de nosotros, dando a Inkscape una difusión boca a boca que creemos que es importante. Todos nuestros usuarios y desarrolladores sirven como embajadores de Inkscape y otros juzgarán a Inkscape basándose en lo bien que nos comportemos. Es importante que todos seamos amables y amistosos, de forma que logremos que Inkscape sea un proyecto en el que la gente disfrute trabajando y usándolo. Cualquier evangelización se derivará de esto de forma natural. Un pensamiento generalizado en la comunidad es que preferimos calidad sobre cantidad, así que por favor no seas demasiado insistente cuando evangelices. Queremos trabajar con otras aplicaciones, en lugar de "matar" otros programas, así que los comentarios en este sentido son contraproducentes. Necesitamos administrar las expectativas. Queremos que los usuarios se sorprendan de lo mucho que Inkscape hace, no que se desanimen al ver que no iguala a otros programas punto por punto. Inkscape debe ser concebido por los artistas como otra forma de ser creativo que complementa sus actuales habilidades y herramientas.

  • Escribe artículos. Publica artículos en medios digitales, o impresos. ¡No olvides incluir un enlace a Inkscape!
  • Realiza capturas de pantalla. Sobre todo de nuevas características.
  • Crea ejemplos. Los Examples son útiles para mostrar las diferentes formas en las que Inkscape puede ser usado. Toma capturas de pantalla, escribe textos y envíalos a los responsables (via la lista de correo inkscape-devel) para añadirlos al sitio.
  • Trabaja en el sitio web. Siempre se agradece la ayuda en el sitio. Se requiere conocimiento de HTML, y una cierta habilidad con PHP es útil. Consulta el código del sitio en el repositorio Subversion (svn) y envía parches, o pide acceso directo svn y línea de comandos para trabajar con los archivos actuales.
  • Haz presentaciones. Da charlas sobre Inkscape en exposiciones, simposios y otros grandes eventos. Anúncialo en una lista de correo de Inkscape para que lo anunciemos en el sitio web.
  • Recluta a más desarrolladores. Encuentra personas interesadas en programar y anímales a trabajar en Inkscape.

Eres libre de contribuir con tus propios banners o botones para promocionar Inkscape. Los mejores serán enlazados aquí.

Usando Inkscape

¿Cómo puedo rotar objetos?

Inkscape sigue la convención usada por CorelDraw, Xara y otros programas: en lugar de una herramienta de "rotación" separada, debes cambiar a Selector (flecha), hacer click sobre el objeto para seleccionarlo, y entonces hacer click nuevamente en los objetos seleccionados. Los indicadores alrededor del objeto se convierten en indicadores de rotación - arrástralos para rotar. También puedes usar el cuadro de diálogo Transformar para rotaciones precisas y la tecla [, ] para rotar la selección utilizando el teclado.

¿Cómo cambio el color del texto?

El texto es igual a cualquier otro tipo de objeto en Inkscape. Puedes pintar su relleno y su trazo con cualquier color, tal como lo harías con cualquier objeto. La paleta de Muestras, el diálogo de Relleno y Borde, pegar estilos - todo esto funciona sobre el texto exactamente igual que en rectángulos, por ejemplo. Por otra parte, si con la herramienta de Texto seleccionas una parte del texto usando Shift+flechas o arrastrando con el ratón, cualquier método de asignación de color se aplicará únicamente a la parte del texto que está seleccionada.

¿Cómo se insertan símbolos matemáticos u otros símbolos especiales en el dibujo?

Cuando la edición se hace en el lienzo, presiona Ctrl+U, luego digita el código Unicode del símbolo que necesitas. En la barra de estado se mostrará una vista previa del símbolo. Finalmente, presiona Enter. Puedes encontrar una lista de códigos Unicode en unicode.org; por ejemplo, el carácter del signo integral es "222b". Debes tener instalada en tu sistema una fuente que incluya este símbolo; de otra forma verás un rectángulo contenedor.

Cuando la edición del texto se hace en la pestaña Texto del diálogo Texto y tipografía, puedes usar cualquier método de entrada GTK admitido por tu instalación de GTK. Consulta la documentación de GTK para obtener más detalles.

Cuando guardes tu trabajo en formato eps, te recomendamos seleccionar la opción "convert text to path" en la caja de diálogo exportación, para preservar el símbolo.

How can sine curves be made in Inkscape?

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.

How to measure distances and angles?

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.

Does Inkscape support palettes? Where can I "store" and save colours for further use?

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.


How do I get extensions working?

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.

How can I print the tutorials? When printed from Inkscape they don't fit, and I don't like reading on screen.

All tutorials in all languages are available online in HTML at this page and can be easily printed from your browser.

Is there a way to apply a gradient to a stroke so that it bends with the stroke?

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.

I'm trying to make a colored tiling of clones, but the tiles refuse to change color.

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.

I'm trying to apply a gradient opacity mask to an object, but the entire object disappears.

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 throusg). 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 [1].

The PNGs exported by Inkscape have jagged edges/no antialiasing/funny background.

This is a problem with whatever you use to view these PNG files, not with Inkscape. For example, Internet Explorer cannot show PNG files with transparency properly (the beta of Version 7 can, but no final release is available yet). Use e.g. Firefox to view your PNGs. If you absolutely must use IE, 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.

Can Inkscape be used from the command line?

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 via man inkscape after you've installed it.

I'm on Windows, and command line parameters don't seem to work!

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

with

-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.

How to make Alt+click and Alt+drag work on Linux?

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.

KDE

For example, in KDE this is done in Control Center > Desktop > Window Behavior > Window Actions.

XFCE4

Please read xfwm4.html

GNOME

Go to System > Preferences > Windows. You are presented with three options to move windows around: "Alt", "Ctrl" or "Super" (Windows logo key). Choose "Super".

I'm having problems with non-Latin filenames on Linux - help!

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.

How to make Alt+click and Alt+drag work on Mac OS X?

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.

I am working on a machine with operating system xxx which has default language yyy set, but I want to work with Inkscape menus in language zzz (most likely English), how can I set this?

Linux
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).
MacOSX
The official Mac OS X way is to provide .lproj files 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.
Windows
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.
Beware, this change the behaviour for all inkscape users on this machine

I installed a new font on my Windows system, but Inkscape does not see it.

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.

I've installed Inkscape on OS X 10.4.x, but when I run it nothing happens. The interface doesn't appear.

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).

On Linux, Inkscape crashes with "invalid pointer" message

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.

SVG topics

Are Inkscape's SVG documents valid SVG?

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!).

What about flowed text?

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.

What, then, is "Inkscape SVG" as opposed to "Plain SVG" when saving a document?

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.

What SVG features does Inkscape implement?

The main parts of SVG that Inkscape does not support yet are filters, 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.


I have hand-created SVG. Will everything be messed up, if I load and save it with Inkscape?

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 and renderer X show my SVGs differently. What to do?

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.

Inkscape and other programs

Why the split from Sodipodi?

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.

What's the difference between Inkscape and Dia?

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.

Is this intended to replace Flash?

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)

Is Inkscape a replacement for The GIMP or Photoshop?

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.

Will Inkscape be part of the Gnome-Office?

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.

What formats can Inkscape import/export?

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.

What can I do with *.cdr (Corel Draw Vector drawing file) files in Inkscape? I have got my images in *.cdr files and I would like to continue in *.SVG.

  1. Open CDR file Corel Draw. Save it as CGM file. It will save only vector graphics. It will not save bitmap graphics.
  2. 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.)
  3. Select all (CTRL+A)
  4. Export as SVG.
  5. Open SVG file in Inkscape and correct mistakes if they appear.

I exported an SVG file from Adobe Illustrator, edited it in Inkscape, and imported back to AI, but there my changes are lost!

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).


Development topics

What are Inkscape's development goals?

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.

What language and toolkit is Inkscape built upon?

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.

How to create an Inkscape extension?

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).

What's a good way to get familiar with the code?

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.

What is the size and composition 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.

What rendering engine do you use?

Currently we use our own renderer called livarot. We plan to migrate to Cairo when it is mature enough.

What is the development platform?

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.

What is the Linux command to download the code through Subversion?

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_NAME is 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_NAME is the name of the module you want to check out, and BRANCH_NAME is 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 trunk or 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.

How are feature requests selected for implementing?

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.

I'd prefer the interface to look like ...

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.
