| 1 | | Right, so test-full-444-out.png has 1.0 gAMA png chunk. How beautiful. You know that Photoshop, Paint and GIMP until my fixes and FFmpeg do not support gAMA or cHRM chunks? While Chrome, Mozilla and Windows photo viewer do support it? Let me guess, considering your ramp from 0 to 255 uses 186 as Cb=Cr with applying gAMA, gAMA of 1.0 is actually NOT CORRECT, because without applying it (and falling back to sRGB) it will be 128 for Cb=Cr??? WTF. Are you serious right now? Okay, whatever. P.S. test-full-diff.png also has 1.0 gAMA. |
