Color profile missing after convert with -profil param

[raedermmpro]

Hi there,

I convert an original image from CMYK to RGB and also apply the respective profile.

Code: Select all

convert in.jpg -profile sRGB_v4_ICC_preference_displayclass.icc -colorspace rgb -density 150 out.jpg

When I check the embedded profile after conversion with identify --verbose out.jpg the profile is not visible

Code: Select all

Does anyone of you have an idea why this happens?

Thanks in advance!

-colorspace rgb

Why are you doing this? If you really do want to convert to linear colorspace, I suggest you do it with a profile.

As a general rule, don't mix "-profile" and "-colorspace". Use one method or the other, but not both.

Thanks for you comment. I tried out just applying the profile and it seems to work. Now the new profile is embedded in the image. I wasn't aware that mixing "-profile" and "-colorspace" leads to problems. Thanks for the clarification.
