I'll look into it today.
It turns out that the polgon/polyline operations weren't setting the "modified" flag, so the completed image wasn't written to the file. The centroids were drawn using individual line segments, which do set the flag. Fixed in r32731. > For the above test case, the vector formats work even without the > centroids. Vector formats are written sequentially; a FILE* is specified when the "surface" is created, and each operation appends data to the stream. Raster output involves drawing to a framebuffer, which needs to be explicitly written to a file. -- Glynn Clements <[EMAIL PROTECTED]> _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
