Tools

Node tool

• [helper path display, flashing - johan]
• The Node tool can now edit clipping paths and masks of objects on canvas, without releasing them. If the selected object has a clipping path and mask, the corresponding buttons on the controls bar of the tool will be enabled; pressing these buttons will display the editable paths or handles of the clippath or mask. A clipping path is stroked green, a mask is stroked blue (the same colors as those used for them in Outline mode).
• Snapping has been improved (more details in Snapping below)
• When dragging a node handle with Ctrl, it now snaps not only to the 15 degree increments starting from 0 and to the original handle direction, but also to the direction of the opposite handle (if it exists) or of the opposite line segment (if it is a straight line).
• The behavior of the buttons/shortucts that make a node smooth or cusp has been improved:

• If a node is already cusp (diamond shaped), pressing Shift+C again on it will retract both its handles. As this works for any number of selected nodes, you can always retract all handles in all nodes by selecting all nodes and pressing Shift+C twice.
• If a non-smooth node is next to a straight line segment, pressing Shift+S once makes it half-smooth: it now has one handle aligned with that line segment. Another press of Shift+S will expand the second handle as well turning it into a full smooth node. If a node is between two curve segments, Shift+S will expand both handles as before.

Tweak tool

Several new modes are added to the Tweak tool for transforming, duplicating, and deleting selected objects using the same "soft brush" metaphor that the path editing and coloring modes use. Using these new modes, it is easy to "sculpt" scatterings of small objects, such as clone tilings, into complex and naturalistic textures.

• Move mode moves those selected objects that are under the brush in the direction in which you move the brush. This is similar to the Push path mode, except that the Move mode affects entire objects and not parts of the paths under the brush.

• Move in/out mode moves those selected objects that are under the brush towards the cursor (default) or away from cursor (with Shift pressed). This is similar to the Attract/repel path mode, except that the Move in/out mode affects entire objects and not parts of the paths under cursor.

• Move jitter mode moves those selected objects that are under the brush in random directions and by random amounts, but the overall amount of movement depends on Force, pen pressure (if you're using a tablet pen), on the closeness of the object to the center of brush, and on how long you apply the brush.

• Scale mode scales those selected objects that are under the brush down (by default) or up (with Shift pressed). The speed of scaling depends on Force, pen pressure (if you're using a tablet pen), on the closeness of the object to the center of brush, and on how long you apply the brush.

• Rotate mode rotates those selected objects that are under the brush clockwise (by default) or counterclockwise (with Shift pressed). The speed of rotation depends on Force, pen pressure (if you're using a tablet pen), on the closeness of the object to the center of brush, and on how long you apply the brush.

• Duplicate/delete mode randomly duplicates those selected objects that are under the brush (by default) or deletes them (with Shift pressed). The chance of an object to be duplicated and deleted depends on Force, pen pressure (if you're using a tablet pen), on the closeness of the object to the center of brush, and on how long you apply the brush. As with regular Duplicate command, duplicating with Tweak tool places the copies right over the originals, and you may need to use the Move jitter mode to ruffle them apart.

The duplicates created by the tool are automatically added to selection if the originals objects were in selection (e.g. if you're tweaking a group of objects, they are duplicated within that group and are not by themselves selected).

Also, the existing path editing modes of the tool have been rearranged: now Shrink and Grow are one mode (shrinks by default, grows with Shift), and Attract and Repel are one mode (attracts by default, repels with Shift). Here is a complete list of modes and shortcuts of the Tweak tool:

Shift+m, Shift+0	        move mode
Shift+i, Shift+1	move in/out mode
Shift+z, Shift+2	move jitter mode
Shift+<, Shift+>, Shift+3	scale mode
Shift+[, Shift+], Shift+4	rotate mode
Shift+d, Shift+5	duplicate/delete mode
Shift+p, Shift+6	push path mode
Shift+s, Shift+7	shrink/grow path mode
Shift+a, Shift+8	attract/repel path mode
Shift+r, Shift+9	roughen mode
Shift+c	        color paint mode
Shift+j	        color jitter mode

In Color Paint mode, painting with Shift inverts the color you're applying (e.g. when painting with white, Shift will switch applied color to black; blue, to yellow, etc.).

Calligraphy tool

[presets - Aubanel]

Paint Bucket tool

• Paint Bucket is now more tightly integrated with potrace. As a result, memory and CPU usage on each fill operation have been reduced significantly.

Eraser Tool

A new eraser tool has been added. It has two main modes:

• Delete-mode where any shape touched by the tool is deleted completely. This operation is in line with "vector" editing.
• Cut mode where erasing acts similar to erasing in a standard bitmap editor.

Cut mode works for both selected and not selected objects.

Pen and Pencil

Apart from the regular Bezier mode, the pen tool now provides several new modes:

• Spiro mode: This mode automatically applies the new Spiro Splines LPE (see the section on new effects) to any newly drawn path. As mentioned below, it is not yet possible to preview Spiros before the path is finished.

• Zigzag mode: This mode makes it easy to draw many straight line segments in quick succession by disallowing curves (even when the user drags with the mouse).

• Paraxial mode: In this mode, the user can only create straight line segments that are parallel to one of the coordinate axes. Normally, each line segment is drawn perpendicular to the previous one. The direction of the line segment being drawn can be toggled with Shift. When clicking on the start anchor, the path is closed with an L-shaped segment (the direction of which can also be flipped with Shift).

Furthermore, it is now possible to automatically apply predefined vector brushes to path strokes in pen and pencil tools. This is a first step towards this blueprint.

In Pencil tool, the controls bar now provides the Smoothing parameter, changeable in the range from 1 to 100, which controls how much smoothing is applied to the freehand line. Small Smoothing values produce rough lines with many nodes; large values give smooth lines with few nodes. (Previously, this control was only available in Inkscape Preferences.)

Text tool

When editing multiline or flowed text, the PgUp and PgDn keys now work to move the cursor by one screen (i.e. by as many lines as fit into the screen at current zoom).

Live path effects

Notable bug fixes and effect changes

We try to refrain from changing the behavior of LPE's, because it will change appearance in old files when opened in new version of Inkscape (but not in any other SVG viewer or editor). However, when an effect is really broken, we have to fix it:

• The Pattern Along Path effect used to stretch the pattern across discontinuities. This has been fixed; now it treats a discontinuous path as a group of continuous paths and applied the effect separately to each.

New effects

• Sketch: Simulates hand-drawn lines. A set of paramters let you tune the effect. They are all sumerized in this picture.

• von Koch: This effect creates fractal pictures (example). To the input shape are added some transformed (rotated/scaled/slanted) copies of it, and then copies of the copies, etc... to get the final shape. The transforms are defined via a path.

Warning: the complexity of the output path grows exponentially fast with the number of generations. As a guardrail, an (editable) complexity bound is provided, above which the effect is disabled.

• Knot: Creates a knot from a flat self intersecting curve. At each crossing, one string is interrupted to make it look like going under the other. The "sign" of each crossing can be set independantly.

Known limitation: can not be applied to groups nor be shared by different objects.

• Perspective paths: Draw an arbitrary path as if viewed in perspective. This is work in progress. Known limitations (among others): It can only use the first perspective that exists in the document defs, and the perspective cannot be adapted interactively yet (the effect must be removed and reapplied after modifying the perspective). [max]

• Spiro splines are a novel way of defining curvilinear paths developed by Raph Levien. It takes some getting used to, but for certain tasks (such as lettershape design) Spiros have a clear advantage over Bezier curves. Recently, Spiro support was added to the FontForge font editor; now it is available in Inkscape too, which means you can use all the convenient Inkscape path tools (moving and transforming groups of nodes, node sculpting, etc.) on Spiro paths.

A Spiro path is defined by a sequence of points, but unlike a regular path with Bezier curves, all Spiro points lie on the path and there are no off-path handles. The curvature of the path is defined entirely by the positions of the points and their types. The path behaves very similar to a springy rod which is forced to pass through the given points and which uses the minimum possible curvature to satisfy the requirement. As such, it feels quite natural and the resulting path is very smooth - not just superficially smooth (i.e. having no cusps), but smooth at a deeper level, which you can achieve with Beziers only after a lot of laborious tweaking.

To create a Spiro path, select any path and assign the "Spiro spline" path effect to it. There are no parameters. Each node of your path becomes a point of a Spiro path, depending on the type of node:

• Smooth nodes (those with two collinear Bezier handles; use Shift+S to make a node smooth) become smooth curve points of the Spiro path. Note that the length or direction of the Bezier handles of the source path is ignored; the only thing that matters is their collinearity.

• Cusp nodes of the source path become corner points of the Spiro path, like free hinges on the springy rod. Between two corner points, the path is always a straight line. To make a node cusp, retract its Bezier handles by Ctrl+click, or press Shift+C and move one of the handles so they are no longer collinear.

• Half-smooth nodes - those with one Bezier handle collinear with a straight line segment on the other hand - become "left" or "right" points on the Spiro path which behave exactly the same: they sit between a straight line and a curve and enforce that these two segments join smoothly without a cusp. To create such a node, make sure one of the segments is a line (select its ends and press Shift+L), then Ctrl+drag the remaining handle to make it snap to the direction of the straight line segment on the other side, or press Shift+S to lock it to that direction.

Note that what matters is the actual collinearity of a node's handles, regardless of the node type that the node has in the Node tool; for example, if a node designated as cusp (diamond-shaped) has collinear handles, it will become a smooth curve point of the Spiro path.

Some configurations of points do not converge and produce wild loops and spirals instead of a smooth curve. According to Raph, "The spline solver in this release is _not_ numerically robust. When you start drawing random points, you'll quickly run into divergence. However, "sensible" plates based on real fonts usually converge." Avoid too sharp changes in direction between points to prevent divergence. Hopefully, the robustness of the algorithm will be improved in future releases.

For now, to edit Spiro paths viewing the result in real time, you have to use the Node tool; it is recommended to turn off the red highlight of the source path as it is a distraction. The Pen tool does not yet allow you to preview a Spiro as you draw, although you can paste the Spiro effect on the path and see the result as soon as the path is finalized.

You can always use the Node tool to continue a Spiro path by duplicating and dragging away its end nodes. Also, when you have a Spiro path selected, you can add a new subpath to it with Pen or Pencil if you start drawing with Shift.

New features

• The Paste Path Effect command is enabled to assign the path effect of the clipboard to any number of paths, going recursively into groups if necessary.

• A new command, Remove path effect removes any path effects from all selected objects, going recursively into groups if necessary.

• Along with the commands to open the path effects dialog and to paste path effects, the three commands were collected in a submenu under Path menu.

• Live path effects can now be assigned to the sides of a 3D box (use Ctrl+click to select individual sides).

• The Pen and Pencil tools now correctly work with paths with LPEs: you can continue such a path or add a new subpath to it by drawing with Shift, all preserving the effect applied to it.

• Path type parameters can now link to existing shapes and text, like clones do. Now it is possible to use text as input for the Pattern Along Path effect for example!

• Lib2geom now has an implementation for EllipticalArc. For Inkscape, this means that it is now possible to directly copy-paste ellipse shapes on path parameters (e.g. 'pattern' in Pattern along Path), without the need to convert the ellipse object to path first. [needs coding and checking]

Live Path Effects for groups

LPE can now be assigned to a group. For most LPE, the effect is applied recursively but for Bend Path or Deformations the result is more powerful : the distortion applies on the whole group.

• You can as usual enter the group by double-clicking on it.
• It applies recursively, this means that a LPE can be assigned to groups of groups
• The Effect can be applied definitively with "Convert Object to path"

Live Path Effects stacking

With Live Path Effects stacking, more than one Live Path Effect can be assigned to an item. A new UI was created to control the stack.

Import/Export

PostScript and EPS import

Inkscape's capability to open or import PS and EPS files now uses Ghostscript instead of pstoedit. If you need to open files of these types, install Ghostscript and make sure the directory with ps2pdf from Ghostscript installation is in your PATH. On opening, you will see a preferences dialog which, for multipage PS files, allows you to select the page to open.

PostScript and EPS export

The new PS and EPS exporter uses cairo and provides a much better support for various vector features, including clipping paths, patterns, and non-ASCII characters. Those features that are not supported by the Postscript language, such as transparency, are exported via rasters embedded into Postscript.

Corel DRAW files import

Now Inkscape can import more Corel DRAW files of following types:

• Corel DRAW Compressed Exchange files (CCX)
• Corel DRAW 7-X4 Template files (CDT)
• Corel DRAW Presentation Exchange files (CMX)

Text objects are not supported as of UniConvertor 1.1.1.

sK1 files import

Inkscape uses UniConvertor to import sK1 files. Text objects are not supported as of UniConvertor 1.1.1.

CGM import

Inkscape uses UniConvertor to import Computer Graphics Metafile (CGM) files. Text objects are not supported as of UniConvertor 1.1.1.

PDF export

The new PDF exporter correctly translates into PDF clipping paths and patterns (requires a recent version of cairo).

With PDF export, it is now possible to make the PDF page the size of the entire drawing, instead of the same as SVG page as before, by the "Export drawing, not page" checkbox in PDF export options. Also, you can export a single object from a complex document to PDF if you specify the ID of that object in the "Limit export to the object with ID" field; the page of such PDF will be the same size as the bounding box of that object and will show only that object (all others will be hidden).

The same capabilities are available from the command line by using --export-area-drawing and --export-id=ID parameters with --export-pdf (previously, they only worked for PNG export).

PDF import from the command line

Now you can use, for example,

inkscape file.pdf --export-plain-svg=file.svg

It will take the first page of the PDF and all the default import options, and save the result to SVG. (Before, it crashed because it tried to open the PDF import preferences dialog and could not do it in the command line mode.) If you try to import PDF without an --export command, it will show the prefs dialog as before and open the file in the UI.

HPGL export

Inkscape can now export to HPGL (Hewlett-Packard Graphics Language). It is a file format that is used for various cutters/plotters.

JavaFX export

[]

DXF export

DXF export is much faster than in previous versions.

PNG export

PNG export has been updated to include metadata if present in the source SVG.

Autosave

Autosave has now been added to allow for automatic timed backups as work goes on. Saved versions are put in a designated directory and do not overwrite the original SVG file and each other. Go to Inkscape Preferences, Autosave tab, to enable this feature and specify the backup time interval, the directory, and the maximum number of saved backups (if this number is exceeded, old backups will start to be deleted).

Extension effects

New and improved effects

• The new Arrange > Restack extension restacks the Z-order of selected objects, from left to right, top to bottom (or vice versa), with radial outward or inward or by an arbitrary angle, specifying the base point for comparison (top, left, middle, etc.).
• The improved Modify Path > Add Nodes extension now also allows segments to be divided into a given number of subsegments.
• The new Render > Alphabet Soup extension is a vector rework of Matt Chrisholm's GPLed script [1]. Alphabet Soup randomly mashes glyph-elements together to make exotic looking text.
• The new Render > Cartesian Grid extension plots Cartesian (square) grids that do not fill the page, but offer three levels of division, logarithmic scales (with clutter-reduction and arbitrary base) and customisable line width. All like elements (eg x-axis subminor divisions) are put into subgroups together. A proper border is also drawn, with an independent line thickness.
• The new Render > Polar Grid extension plots a polar co-ordinate grid, with options for arbitrary-base logarithmic subdivisions, clutter-reduction around the origin, circumferential labels and custom line widths.
• The new Text > Convert to Braille extension recodes English (or just Latin letters) text to Braille code created for visually impaired people.
• [preset filter effects]

API changes

While the "Live preview" checkbox is useful for most effects, for some it just does not make sense. Now, you can add the attribute needs-live-preview="false" in the effect element in the .inx file of the effect to suppress this checkbox for your effect.

Parameters passed to extensions (via the <param> element) now have a new boolean attribute - gui-hidden to indicate that the parameter should not be represented in the GUI. If all parameters are marked as hidden no GUI is presented for such extension.

All .inx files are now properly formatted XML files with its own namespace of: http://www.inkscape.org/namespace/inkscape/extension and a Relax NG schema to define it. More information can be found in the Extensions Article.

SVG output

Optimized CSS properties

• As a file size optimization, Inkscape does not write into SVG some of the stroke properties if the object has stroke:none and some of the fill properties when it has fill:none. The only situation where this might affect you is if you remove stroke from an object and then turn it back on - the object will get the default stroke instead of the same it had before.

Also, in manually-edited SVG where a parent group has no stroke but sets some stroke properties to be inherited by its descendants, you will need to set stroke property to other than none on the group, and suppress inheritance with stroke:none on those children that don't need it.

Specifically, if stroke:none, the following properties do not get written to SVG:

stroke-width
stroke-linecap
stroke-linejoin
stroke-miterlimit
stroke-opacity
stroke-dasharray
stroke-dashoffset

Note that this does not include marker properties, which means you can still have markers on a path without visible stroke.

If fill:none, the following properties do not get written to SVG:

fill-opacity
fill-rule

• The opacity property is not written if it has the default value of 1 (this property is not inherited, so the change should have no side effects).

• The marker-start, marker-mid, and marker-end properties are not written if the marker property is already present with the same value.

Optimized path data

In this version, the size of the path data written in the d= attribute of path elements is reduced by about 10%. Inkscape generates the shortest possible path strings by avoiding repeated operators and using relative coordinates (when it helps).

This is controlled by the SVG output page of Inkscape Preferences dialog, as well as the following attributes in group id="svgoutput" in your preferences.xml file:

• allowrelativecoordinates (default 1) to switch relative coordinates on (1) or off (0)
• forcerepeatcommands (default 0) to force repeating operators (1) or allow use of the more compact representation without repeated operators (0)

No more explicit closing line segment

Inkscape used to always explicitly write the closing line segment to SVG for closed paths. For example: "M 0,0 L 1,0 L 1,1 L 0,1 L 0,0 z". With the improved SVG path data writing, Inkscape no longer generates this closing line segment, resulting in "M 0,0 L 1,0 L 1,1 L 0,1 z". When SVG path data input contains this explicit closing segment, it is maintained throughout transformations, but is removed after using the node edit tool. [this seems no longer to be true, fix it!!! -johan]

Horizontal and vertical path segments

If an SVG contains paths with shorthands for horizontal and vertical path segments ('H' or 'V'), then Inkscape will try to maintain those shorthands if possible, so the saved file will also contain them.

<script> support

While Inkscape does not yet support SVG scripting via the <script> element, this element is now preserved after editing the file in Inkscape.

Other features

Shell mode

If you run inkscape with --shell, it will enter an interactive command line shell mode. In this mode, you type in commands at the prompt and Inkscape executes them, without you having to run a new copy of Inkscape for each command. This feature is mostly useful for scripting and server uses: it adds no new capabilities but allows you to improve the speed and memory requirements of any script that repeatedly calls Inkscape to perform command line tasks (such as export or conversions). Each command in shell mode must be a complete valid Inkscape command line but without the Inkscape program name, for example:

$ inkscape --shell
Inkscape 0.46+devel interactive shell mode. Type 'quit' to quit.
>file.svg --export-pdf=file.pdf
>otherfile.svg --export-png=bitmap.png
Background RRGGBBAA: ffffff00
Area 0:0:744.094:1052.36 exported to 744 x 1052 pixels (90 dpi)
Bitmap saved as: bitmap.png
>quit

Clipboard enhancements

The clipboard used by Inkscape is now system-wide instead of being confined to a single instance of the application. Copied elements are exported to the clipboard using all the available output formats. SVG data can be pasted into other applications supporting one of Inkscape's output formats, and SVG data provided by other applications can be pasted into Inkscape.

If you copy a string that can be interpreted as a hexadecimal color specification, i.e. 2f7ab4 or #014522b0, and then paste it into Inkscape, the fill of the selected objects will change to the given color. This is especially useful when working with HTML pages.

Masks and clipping paths

[editable in node tool - johan]

Stroke width changeable by dragging

Similar to editing the fill or stroke colors by dragging away from the swatch in the status bar, which was added in the last version, this version allows you to drag away from the stroke width value displayed there to change the stroke width of selection. Dragging above the 45-degree line from the swatch increases the width (up to twice the original width), dragging below it decreases the width (down to half the original width). With this feature, quick and precise stroke width adjustments are possible without opening any dialogs or menus.

Enhanced tablet support

Input device tool switching

Tablets and other input devices that report separate hardware are now recognized and current tool and/or settings can be set to switch in response to the physical tool being used.

Extended input device configuration

The stock Input Devices dialog has been replaced with a completely redone version that provides a more useful representation of settings. It also contains a simple area for testing different inputs of different devices.

Additionally hardware setup itself has been separated from general settings to allow for easier dynamic switching of settings appropriate to the task at hand.

Layers

Show/hide other layers

The layers dialog now allows for hiding or showing all layers other than the current layer. This "solo" feature allows for faster switching between working layers and for quick checking with and without others shown.

Duplicate Layer command

A new command has been added to the layers menus to allow for duplicating an existing layer with all of its objects.

External image editing and reload

Linked bitmaps have a context menu option to launch editing in an external application. Linked images now will reload when the linked file changes on disk. Both the external editor application and the reload behavior can be controlled by user preferences.

Command for relinking clones

A new command, Relink Clone to Copied in Edit > Clone, allows you to relink any clone to a different original object without changing its other properties. Just copy (Ctrl+C) the object you want to be the new original, select any number of clones, and choose the Relink command. Now all selected clones are linked to the copied object.

Auto relinking clones on Duplicate

If you turn on the When duplicating original+clones: Relink duplicated clones option on Clones tab of Inkscape Preferences (default is off), duplicating a selection containing both a clone and its original (possibly in groups) will relink the duplicated clone to the duplicated original instead of the old original.

Pattern editing

When editing pattern fills:

• The pattern origin and scale handles now snap.
• The pattern scaling can now be different in X and Y direction. Press Ctrl to have a fixed 1:1 ratio scaling (old behavior).
• The handles are now positioned at the corners of the unit cell, instead of only a quarter of that cell as before. So, now a rectangle filled with pattern will have all of the pattern handles in the corners, making it harder to manipulate them. However, the handles can be dragged outside the rectangle by moving the pattern's origin handle.

Transform dialog: spacing out option

Previously, the Apply to each object separately checkbox had no effect for the Move tab. Now, if several objects are selected, this checkbox is on, and "Relative move" is on, each object is shifted relative to the closest selected object on the left (for X) or below (for Y).

For example, if you have a horizontal row of objects and you move them relatively by X=5px with "Apply to each object separately" on, the leftmost object will shift by 5px, the next one to the right by 10px, and so on; the rightmost selected object is displaced by 5*n px where n is the number of selected objects. As a result, the distance in each pair of adjacent objects will increase by 5px and the whole row will be spaced out, much like a letterspacing adjustment spaces out a text string. Moving these objects by X=-5px will, conversely, squeeze them tighter together: the leftmost will move by -5px, the next one by -10px, and so on. For Y, the effect is the same except that the move starts from the object closest to the bottom (i.e. with smallest Y coordinate).

When determining the order of shifting objects, for X, the left edges of their bounding boxes are sorted horizontally, and for Y, the bottoms of their bounding boxes are sorted vertically. Order of selecting the objects or z-order does not matter.

User interface

Filters can be disabled

In order to facilitate editing documents that use lots of SVG filter effects, filter effects can now be disabled for a particular document window by selecting View|Display mode|No Filters from its menu. This provides an intermediate step between "normal" and "outline" view modes.

The Toggle view command in the Display mode submenu (Ctrl+keypad 5) toggles between the outline view and either regular or no-filters view, depending on which was used most recent.

Native file dialogs for Windows

The windows builds of inkscape now have Windows-native file dialogs to keep consistency with other windows applications.

Inkscape Preferences dialog

This dialog has been rearranged for more logical grouping of options. New pages has been added: Bitmaps (options for the new update-on-file-change and external editor features), UI (options for toolbar icon sizes), and SVG Output (options for SVG formatting, introduced in 0.46 and now editable from the dialog as well).

A new option on the Bitmaps tab, Resolution for Create Bitmap Copy, allows you to set the resolution of the bitmap created by the corresponding command (by default bound to Alt+B). The default value of 90 dpi forces the resulting bitmap to align with the default 1px-spaced grid on the canvas.

There is a new option on the Interface tab, Zoom correction factor, which displays an adjustable ruler. Move the slider until the ruler's on-screen size matches its true size. The resulting conversion factor is used internally when zooming to 1:1 etc. such that objects are displayed in their true size.

Align and Distribute dialog

There is now an option to treat all selected objects as a group when aligning (this spares the user the trouble to manually group them, align, and ungroup afterwards).

Dropper tool

The confusing icons on buttons in the controls bar of the Dropper tool (pick/assign opacity) are replaced by text labels.

Swatches

Hovering over a swatch now shows the name of the swatch in the status bar. This makes it easier for tablet users to identify a swatch by name, as holding a stylus still enough to show a tool tip is difficult.

Toolbars

• The toolbar icon sizes for the three main toolbars are now separately configurable and to a few different sizes. This allows users to get a smaller UI on certain systems, including Ubuntu.

• The main tools toolbar has been converted to a standard GtkToolbar, removing the problem of it pushing the main window taller. Tools that don't fit automatically flow into a popup menu.

• When torn off, toolbars now keep the size they last had in the main window. They can be resized by docking, sizing the main window, and then undocking agin.

• Some controls (such as the Width in Calligraphic/Tweak/Eraser tools, Tremor, Wiggle, and Mass in Calligraphic, Threshold in Paintbucket, Tolerance in Pencil) are converted from numeric editable fields into draggable sliders, with labels and values (usually in the range 0..100) displayed on top. As these values don't usually require much precision, this makes adjusting them much easier and faster.

Title and Description

• [the Title and Description fields on the Object Properties dialog - sas]

Clone/original visualization

When you press Shift+D to find and select the original of the selected clone, Inkscape draws a dashed line between the centers of the bounding boxes of the clone and the original. This line disappears after one second.

Grids, guides, snapping

Grids

• The dotted rectangular grid now shows small crosses at the intersection points of emphasis lines.

Guides

There is now an option to treat groups as single objects during conversion to guides (as opposed to converting each object inside the group separately).

Snapping

Snapping has been implemented or improved in these areas:

• The node tool now snaps to any unselected node (cusp or smooth) within the path that's being edited, and to cusp nodes of other paths. It also snaps to the path itself, but only to the stationary segments in between two unselected nodes. It is now also possible to snap while moving nodes along a vertical or horizontal constraint
• Clipping paths and masks are now also snappable
• The object snapper now also allows to snap to the page border
• It is now possible to snap to intersections of paths (were we previously only snapped to intersections of line-segments)
• In the selector tool, snapping while skewing or constrained translating have been improved
• When creating new shapes, all of their handle points now snap
• In the document properties dialog, the checkbox for 'always' snap has been replaced by two radiobuttons; this should eliminate most of the confusion surrounding this option
• Holding the shift-key now also disables snapping while dragging node-handles
• The code relating to the snapping mechanisms has undergone major refactoring to make it more reliable and easier to use from a developer's perspective
• Snapping to objects now uses routines from the 2geom libraries, which are actively maintained and are less error prone than the old Livarot libraries. This fixes at least two known snapping bugs
• While drawing and constraining to specific angles (using CTRL), Inkscape should now only snap to points on the constrained line.
• When pasting, previously aligned originals will stay aligned to the grid. The code for this had to be reinvented due to the refactoring

Snap indicator

When snapping has occurred, an indicator is displayed at that specific position. For now that indicator is just a cross that disappears in a second. In the future the shape of the indicator will be related to the type of target that has been snapped to. The snapping indicator can be disabled in the Document Properties dialog.

Notable bug fixes

• Inkscape is now able to handle paths with only 'movetos', i.e. "M 0,0 M 1,1 M 2,2". These kind of paths can be used to only show markers on a path without the rest of the path visible.

• The visual bounding box (which is the default bounding box type used by Inkscape) of an object with a filter applied, now includes the expanded area of the filter. For single blur filter (such as the blur you apply with a slider in the Fill and Stroke dialog), this expands the bounding box by 2.4*radius; although theoretically, blur is infinite, this is the distance at which the opacity of the object drops below the perceptibility threshold of our renderer. For all other filters, the area is expanded by the relative amounts you specify on the "Filter general settings" tab of the Filter Effects dialog.

Only visual bounding box is affected; if you use geometric bounding box, you will notice no change in most cases. However, the Export bitmap dialog always uses the visual bbox for selection of the export area; this means that you can now export a blurred object to bitmap without any clipping of the blur.

• Bounding box calculation does not include the invisible objects. (#252547)

• Several fixes allows Inkscape to correctly render and edit SVG files that use currentColor in objects' style (this includes files created by gnuplot).

• No more ID clashes on import and paste: previously, importing or pasting SVG objects might sometimes distort their colors, because the imported objects referred to gradients with the same IDs as those that already exist in the document but look different. Now, IDs of all gradients in the pasted document are checked for clashes with those in the host document, and if necessary changed with all their users updated correspondingly, so such unexpected color changes will never happen.

• Clipboard is system-wide: you can now copy/paste objects between different Inkscape instances as well as between Inkscape and other applications (which must be able to handle SVG on the clipboard to use this).

• File dialogs remember last visited directory

• No more garbage lines in outline mode

• No more artifacts left by the circle cursor in Tweak tool

• The Live Path Effects Bend Path and Pattern along Path now work correctly with closed paths.
