Hi.

When I open the test images there (with display):
http://www.color.org/version4html.xalter
I get just the results which would mean that color spaces (both ICC v2 and v4)
are ignored.

Cheers,
Chris.

Interestingly,... it DOES seem to work, when using their test PDF (which
contains the same images)... so WTF?! is going on here? ^^

And it does neither work, when I convert the test JPGs to TIFF (e.g.
with eog, color support works with JPG, but not with TIFF)...

Cheers,
Chris.

ImageMagick dépends on liblcms. Have you installed the non free profiles?

I have but that shouldn't change anything, should it? Cause the profiles
are embedded in the images themselves and should be loaded from there.

The icc-profiles* packages are rather for programs like GIMP/etc. when
you want to create something _new_ in some color space.


Cheers,
Chris.

Control: tag -1 + wontfix

this is not a bug but intended behaviour:

https://github.com/ImageMagick/ImageMagick6/issues/146#issuecomment-817167036

I attached the image with v2 GBR profile (lower left). Just running

    $ display Lower_Left.jpg

indeed shows the wrong colors. According to the IM devs you have to explicitly
state the destination profile or otherwise "display" will only draw raw pixel
values. So this works:

    $ display -profile /usr/share/color/icc/sRGB.icc Lower_Left.jpg

Thanks!

cheers, josch
