pngtogd2 problem

I am having trouble converting png images to gd2 images. The command I am running is
"pngtogd2 filename.png filename.gd2 0 1" as recommended on the nagios faq. However whenever I put filename.gd2 into the vrml_image field all I get is a square green box.

simon,
it’s been a long time since i’ve done this, but if i recall correctly, i had to play around with the chunk size before it worked right. try something like ‘pngtogd2 filename.png filename.gd2 1 1’ and see how that works. you might also want to create a .png from scratch with photoshop or something similar and then try to convert to .gd2 to see what happens.
