Inkscape is an Open Source vector graphics editor, with capabilities similar to
Illustrator, Freehand, CorelDraw, or Xara X using the  W3C standard Scalable 
Vector Graphics (SVG) file format. Supported SVG features include shapes, paths,
text, markers, clones, alpha blending, transforms, gradients, patterns, and 
grouping. Inkscape also supports Creative Commons meta-data, node editing, 
layers, complex path operations, bitmap tracing, text-on-path, flowed text, 
direct XML editing, and more. It imports formats such as JPEG, PNG, TIFF, and 
others and exports PNG as well as multiple vector-based formats.

Inkscape requires boost, libsigc++, glibmm, gtkmm (which requires cairomm), 
and gc,  all of which are available at SlackBuilds.org.
