2.7.
Basic vector support
Using the GFig plug-in, the GIMP now supports the
basic functionality
of vector layers. The GFig plug-in supports a number of vector
graphics features such as gradient fills, Bezier curves and curve
stroking. It is also the easiest way to create regular or irregular
polygons in the GIMP. In the
GIMP 2.2, you can create GFig layers, and
re-edit these layers in GFig afterwards. This level of vector support
is still quite primitive, however, in comparison to dedicated
vector-graphics programs such as Inkscape.
