Inkscape

An Open Source vector graphics editor, with capabilities similar to Illustrator, CorelDraw, or Xara X, using the W3C standard Scalable Vector Graphics (SVG) file format.

Inkscape supports many advanced SVG features (markers, clones, alpha blending, etc.) and great care is taken in designing a streamlined interface. It is very easy to edit nodes, perform complex path operations, trace bitmaps and much more. We also aim to maintain a thriving user and developer community by using open, community-oriented development.

Current Features

Object creation

Drawing: pencil tool (freehand drawing with simple paths), pen tool (creating Bezier curves and straight lines), calligraphy tool (freehand drawing using filled paths representing calligraphic strokes)
Shape tools: rectangles (may have rounded corners), ellipses (includes circles, arcs, segments), stars/polygons (can be rounded and/or randomized), spirals
Text tool (multiline text, full on-canvas editing)
Embedded bitmaps (with a command to create and embed bitmaps of selected objects)
Clones (“live” linked copies of objects), including a tool to create patterns and arrangements of clones

Object manipulation
Affine transformations (moving, scaling, rotating, skewing), both interactively and by specifying exact numeric values
Z-order operations
Grouping objects, with a way to “select in group” without ungrouping, or “enter the group” making it a temporary layer
Layers, with a way to lock and/or hide individual layers, rearrange them, etc; layers can form a hierarchical tree
Copying and pasting objects
Alignment and distribution commands

Fill and stroke
Color selector (RGB, HSV, color wheel)
Color picker tool
Copy/paste style
A gradient editor capable of multi-stop gradients
Pattern fills (bitmap/vectors)
Dashed strokes, with many predefined dash patterns
Path markers (e.g. arrowheads)

Operations on paths
Node editing: moving nodes and Bezier handles, node alignment and distribution, etc.
Converting to path (for text objects or shapes), including converting stroke to path
Boolean operations
Path simplification, with variable threshold
Path insetting and outsetting, including dynamic and linked offset objects
Bitmap tracing (both color and b/w)

Text support
Multi-line text
Uses any installed outline fonts, including right-to-left scripts
Kerning, letterspacing, linespacing adjustments
Text on path (both text and path remain editable)
Text in shape (fill shape following stroke)

Rendering
Fully anti-aliased display
Alpha transparency support for display and PNG export
Complete “as you drag” rendering of objects during interactive transformations

Misc
Live watching and editing the document tree in the XML editor
PNG and PostScript export
Command line options for export and conversions
Perfectly compliant SVG format file generation and editing
