I made changes to avoid converting the .rgb to .png for testing on linux.
But it looks like there's no widthxheight header information being written, and graphicsmagick installed on ubuntu asks for that information if I go 
gm display 1_wrl.0001.rgb 
(whereas gm display 1_wrl.0001.png displays the image without having to ask)
When I look for an .rgb format, SGI has a .rgb format, and they specify a header.
ftp://ftp.sgi.com/graphics/grafica/sgiimage.html 
http://www.fileformat.info/format/sgiimage/egff.htm 
and the Snapshot.c code doesn't write a header - just the body, and looks like not in the byte order of the .sgi format.
freewrl linux uses imlib2 for reading images. Perhaps imlib2 could be used to save the snapshot images directly to .png, and in such a way that there's no compression, if compression is a problem.

Or during the current image conversion method, specify no compression, if compression is a problem.
