(I use pnmtopng because GIMP cannot save PNG images properly.)
What pnmtopng tries to say below? How to fix it?
All PNM images have the same P6 format.
pngtopnm Screenshot-79.png | pnmcut 7 50 1012 688 | pnmtopng > 09.png
pngtopnm Screenshot-80.png | pnmcut 7 50 1012 688 | pnmtopng > 10.png
pnmtopng: 256 colors found
09.png: PNG image data, 1012 x 688, 8-bit/color RGB, non-interlaced
10.png: PNG image data, 1012 x 688, 8-bit grayscale, non-interlaced
"convert" of GraphicsMagick does the conversion properly with image 10.
