Some of my script are failing in comparison to IM 7.6.4.10 when processing grayscale images. I find differences simply looking at the verbose info of the grayscale jpg using both releases.
Input:
That is in IM 6.7.4.10 the verbose info shows:
im6 convert clown.jpg -verbose info:
rending intent of none
no chromaticity values.
In the current 6.7.6.9 release it show:
convert clown.jpg -verbose info:
Rendering intent: Perceptual
Gamma: 0.454545
Chromaticity:
red primary: (0.64,0.33)
green primary: (0.3,0.6)
blue primary: (0.15,0.06)
white point: (0.3127,0.329)
I thought grayscale images were going to be treated as linear. Please clarify. Can we go back to linear grayscale images?
