The last value should always be in the range 0-255 if not a color name.

Re: convert with -depth8,but output was # ImageMagick pixel enumeration: 500,500,65535,srgb

ImageMagick txt: reports values in the Quantum depth of your install, not according to your depth. So if you are on Q16, it will report 65535. If on Q8, it will report 255 On my Q16 ImageMagick, convert logo: -depth 8 txt: # ImageMagick pixel enumeration: 640,480,65535,srgb 0,0: (65535,65535,65535)...

Re: Writing and Reading TXT images problems

What version IM, on what platform? For the past few years, when IM creates an images, it encodes the image as non-linear sRGB. You then convert your image to linear RGB with "-colorspace RGB". This converts the very low value 1/255 to become 0/255. Awesome!!! Thanks for your help. And sorry for my ...
