-intent and -black-point-compensation options does not work

[ivants]

Both -intent Perceptual and -intent Relative produces identical results. Same with -black-point-compensation.
This is IM bug or I just not understood something?

Thanks

What profile are you using? Does it have perceptual and relative intents?

[ivants]

Yes, I try to use Photoshop Uncoated Fogra CMYK profile

What is your command? What version of IM are you using (and what platform).

[ivants]

Windows 7
ImageMagick-6.8.5-Q16

Intent switching works, there was my mistake, but BPC still not working:
convert image.tif -intent Relative -profile Uncoated.icc -black-point-compensation OUT_NEW2_rel_bpc.tif

[snibgo]

IM performs the operations and settings in the order you provide them. "-black-point-compensation" is a setting that changes the operation of any following "-profile", so needs to be placed before it:

Code: Select all

convert image.tif -intent Relative -black-point-compensation -profile Uncoated.icc OUT_NEW2_rel_bpc.tif

[ivants]

Thank you for pointing me on that. Everything works fine
Sorry for false bug report
