不想花錢買Illustrator，Inkscape能畫出什麼

What's new in this version:

RELEASE HIGHLIGHTS:
- Mesh Gradients are now supported
- Many SVG2 and CSS3 properties are now supported (e.g. paint-order, mix-blend-mode). Not all are available from the GUI
- The new Object dialog allows to select, label, hide and lock any object in the drawing from a dialog that lists them all
- Selection sets make it possible to 'group' objects together regardless of document structure
- Guides can now be locked to avoid accidental movement
- Several new path effects have been added, among them Envelope/Perspective, Lattice Deformation, Mirror and Rotate Copies
- There are several new extensions (e.g. a seamless pattern extension) and a new filter (colorblindness simulation) included in the release, many old extensions have been updated or got new features
- Spray tool and measure tool received a set of nifty new features
- Interactive smoothing for lines created with the Pencil tool
- BSplines (and more) are available for the Pen tool
- Checkerboard background can be used to more easily see object transparencies

IMPORTANT CHANGES:
- The default resolution was changed from 90dpi to 96dpi, to match the CSS standard. For more background information, please see the Wiki article about handling of units in Inkscape. Inkscape 0.92 will attempt to identify 'legacy' Inkscape files that need to be converted
- For developers and packagers, the switch from autotools to CMake is a relevant change (users who do not compile their own version will not be affected). While the old system is still available for 0.92, it is now also possible to compile Inkscape using CMake

MANIPULATING OBJECTS:
Objects Dialog:
- New dialog for manipulating the object tree
- Drag and drop reordering of objects
- Lock, and hide one or more items
- Use Ctrl+F to search for an item
- Select one or more objects in the drawing
- Shows individual objects as well as layers
- Ability to change highlight color of objects
- Ability to set blend mode per object
- Imported from Ponyscape

Selection Sets Dialog:
- New dialog that allows the creation of selection sets that are not affected by document structure

TEXT:
Font Features:
- It is now possible to take advantage of OpenType tables to select alternative glyphs from a font. For this, a third tab ('Variants') has been added to the 'Text and Font' dialog. Note that browser support is still limited. Inkscape must also be linked with a recent version of the Pango library.

Vertical Text:
- Support for vertical text layout has been improved

Accessibility:
- Converting text to a path will save the text in the 'aria-label' attribute. This is useful for accessibility and could eventually be used by Inkscape to reconstruct the text

Line Spacing:
- Line spacing in Inkscape now follows the CSS standard for the 'line-height' property

LIVE PATH EFFECTS:
- Now some suitable LPEs can be applied to clips and masks
- Helper lines come again to life
- The option to add a bend path directly was added to the pen/pencil shape combo box

PEN / BEZIER TOOL:
- New shortcut to automatically close a path when it is being drawn: Shift + Enter

SPRAY TOOL:
- New eraser mode
- More pressure toggles added
- "No overlap" option with optional multiple elements
- "No overlap" option between different background colors
- Configurable offset for overlaps
- Color picker from center or average area
- Apply picked color to fill
- Apply picked color to stroke
- Invert picked colors
- Spray over transparent background areas
- Spray over non-transparent background areas
- Makes use of "Trace the drawing" options from Tiled Clones dialog

MEASURE TOOL:
- Measure is kept until a new one is made (only visible when using measure tool)
- Repositioning of origin/end
- Convert to object
- Convert to guides
- Add just the distance measurement, consisting of editable text and a line indicating start and end
- Display a 'phantom measurement' temporarily to be able to compare two measurements
- Reverse origin/end
- Measure global
- Measure only current layer
- Change precision

GRADIENT TOOL:
- To accomodate for keyboards that do not have an Insert key, the keyboard combination Shift+I can now also be used to insert a new stop into a gradient.

ALIGN AND DISTRIBUTE:
- NEW: drop-down chooser with options to align nodes relative to each other in node editing mode

IMPORT / EXPORT:
- Export PDF / EPS / PS
- Export Optimized SVG
- Export to PNG

EXTENSIONS:
New:
- Render > Seamless Pattern (Screencast)
- Images > Set Image Attributes (Bug #1357808, can be used to fix the scaling problem of raster images in SVGs created with previous Inkscape versions)
- Render > NiceCharts (github repo, not maintained)
- Arrange > Deep Ungroup (Bug #171117)

Plotter Driver:
- Multiple Pens
- Serial Connection

HPGL Export:
- The HPGL export (File -> Save as -> HP Grafics Language file) has now the same multiple pens feature as the #Plotter Driver.

HPGL Import:
- The HPGL import (File -> Open -> Select .hpgl file) can now import multiple pens into corresponding layers, see #Plotter Driver for more information.

PDF Import:
- The image 'interpolate' value is now used to determine how to display bitmaps (interpolated or blocky)

Miscellaneous Improvements:
- Arrange > Restack has new options to reverse and shuffle the z-order of selected objects
- Render > Random Tree has new option to omit redundant segments
- Visualize Path > Measure Path has additional text layout options
- Render > Barcode was updated with new EAN2 code and extended EAN13 with automatic EAN2 and EAN5 additions
- Color > Randomize now allows to set the range for randomization, and (with some limits) can now also randomize opacity
- Modify Path > Jitter nodes was partially rewritten and now also supports Pareto and Log-Normal distributions

Extension Development:
- It is now possible for an extension to retrieve a list of selected nodes (See Bug #171287 for an example extension)

FILTERS / BLEND MODES:
New Filters:
- Color > Color Blindness filter allows to simulate different color blindness conditions.

New Blend Modes:
- Blend Modes can now be applied to single objects as well as to layers. In addition to the previously available modes 'Multiply', 'Screen', 'Darken' and 'Lighten', the following modes are now available:
- Overlay
- Color Dodge
- Color Burn
- Hard Light
- Soft Light
- Difference
- Exclusion
- Hue
- Saturation
- Color
- Luminosity

OTHER DIALOGS:
Document Properties: Licences:
- All selectable licences have been updated to most current version

Filter Editor:
- Filter list now displays how often a filter is used

MENUS:
- 'Resize page to selection' added to Edit menu, shortcut: Shift+Ctrl+R
- 'Pop selection out of group' available in context menu of objects which are part of a group, when the group has been entered, and via the 'Objects' menu. It will move the object up by one level in the grouping hierarchy.
- 'Create Clip Group' from context menu groups the selected objects and clips that group with a clone of itself. This allows for quick creation of, for example, inset shadows.

OTHER USER INTERFACE:
Node Snapping:
Snapping in the node tool has been improved:
- When double clicking to insert new nodes, the position of these new nodes will snap to for example path intersections and to path-guide intersections
- When grabbing a segment of a path and dragging it to deform it, the pointer will now snap

Checkerboard Background:
- It is now possible to use a checkerboard background when editing. This allows one to clearly see the transparency of objects. (See "Page" tab of the "Document Properties" dialog.)

View Box:
- One can now set the SVG 'viewBox' attribute from the GUI. This attribute sets the scale of the drawing by determining the real-world value of the SVG user unit (pixel size).

Lock Guides:
- Now guides can be locked and unlocked globally or individually

Panning:
- Panning with space bar can now be deactivated in the Preferences (uncheck Behavior > Scrolling > Mouse Move pans when Space is pressed)

SVG AND CSS:
- The 'marker-orientation' property now recognizes units ('deg', 'rad', 'grad' and 'turn')
- The new SVG 2 'context-fill' and 'context-stroke' properties are implemented which allows the auto-matching of arrowhead fill color to path stroke color
- The new SVG 2 marker orientation attribute value 'auto-start-reverse' is implemented. This allows one arrow marker to be used for both ends of a path
- The new CSS 3 'mix-blend-mode' and 'isolation' properties are implemented, allowing setting the blend mode between objects without using filters
- The new SVG 2 'paint-order' property is now supported. This allows setting the order in which the fill, stroke, and markers are drawn (see the 'Stroke style' tab in the 'Fill and Stroke' dialog)
- The SVG 1.2/SVG 2 'vector-effect' property's 'non-scaling-stroke' value is now supported. This will keep the stroke width fixed regardless of the zoom factor
- The new SVG 2 'mesh' paint server is supported, including bicubic auto-smoothing. A primitive GUI is available
- The SVG 1.1 'text-decoration' property is now rendered (underlines, strike through, etc.). CSS 3 'text-decoration' properties are also rendered
- The new SVG 2 'hatch' paint server is now supported
- The CSS 'white-space' property is now supported. Use of this property was added in SVG 2 to replace the now deprecated 'xml:space' attribute
- The SVG 1.1 'textLength" and 'textAdjust' attributes are implemented, however, there is no GUI for these attributes
- Rendering of the Component Transfer filter primitive has been corrected
- Units are now recognized in the text and tspan 'x', 'y', 'dx', and 'dy' attributes
- Percentage values are now interpreted correctly for shapes
- New SVG 2 and CSS 3 features are generally not enabled in the GUI until widespread support in browsers

NEW DEPENDENCIES:
- The Paintbucket and Trace Bitmap tools now use an external copy of the Potrace library

TRANSLATIONS:
- New UI translations for Assamese, Bodo, Dogri, Gujarati, Hindi, Icelandic, Kannada, Kashmiri (Perso-Arabic and Devanagari), Konkani (Latin and Devanagari scripts), Maithili, Malayalam, Manipuri (Meetei Mayek and Bengali scripts), Marathi, Odia, Santali (Devanagari and Ol-Chiki scripts), Sanskrit, Sindhi, Tamil, Urdu (Perso-Arabic and Devanagari scripts). Many other translatins have been updated and improved.
