 Replying to [ticket:2114 annakrat]:
 > Module m.nviz.image does not create valid image file on Windows.

 was the wingrass version in question built with libtiff support?

 see lib/ogsf/gsd_img_tif.c, nothing too complicated in there.
 gsd_img_ppm.c is even simpler. If header part is ok but writing the rest
 of the ppm image isn't, perhaps gsd_getimage() is returning bad values for
 xsize and ysize?


 > Has m.nviz.image ever worked on Windows?

 I don't know if anyone ever tested that; does saving as tiff or ppm from
 the G6 tcl/tk NVIZ on wingrass work?
