Add-on symbol packages for download
- Convert SVG to EPS format (for use with ps.map) with the following command:
- (requires Inkscape)
inkscape -z -T -E outputfile.eps inputfile.svg
- We still need someone to write a little script to convert EPS images into GRASS's display symbol format. It would be nice if the same converter could create d.graph drawing commands as well.
