Title: The CMYK image shows all wrong when added into Image Frame
Post by: abi on December 09, 2024, 07:24:08 AM
When importing an CMYK image into Scribus

Attached screenshot of actual image on left when viewed in any Image Viewer.

When we import this into Scribus - its shown on right in attachment where all the colors are messed up.

If someone can please help with which color management profile should be set. Attached another screenshot with the current Color Management setting.

Thank you

hi abi

this looks really strange. i have never seen something like that. when i place cmyk images (usually .kra or .tiff, but just tested with .jpg as well), they look correct on screen and export correct.
what file format is it in your case?

if this happens with different images, you should file a bug report (https://bugs.scribus.net/) with an affected .sla file and the used image.

hi abi

i placed your images on test files in scribus 1.6.2, 1.6.3.svn and 1.7.0.svn. all of them looked normal. i wasn't able to simulate your strange color effect (unless i experiment with 'extras' → 'manage images' → 'image tools' → 'image effects' → 'quadtone' or something like that...)

My thoughts too utnik.

abi: did you use a copy of a previous image frame for this image? Specifically one that you added effects to?

I have uploaded a video showing on how we are adding the image and have loaded the settings as well just to confirm that we are not doing anything wrong

Have a look to Right click in image frame to image effects.
It could a negative effect.

hi abi

you don't do anything wrong.
please file a bug report (https://bugs.scribus.net/) (including this screen cast, the image and informations to your operating system and scribus version). you could link to this thread as well.

Lets make sure it isnt a bad config file. Make sure  scribus isnt running, and navigate to the scribus config directory (.scribus), and rename it.(say to .scribusold. Restart scribus, it will remake the config files ad their default setting, and try that image again.

hi abi

as i wrote in the bug tracker, as long as the bug isn't fixed i would convert the images into another format (i.e. .tif).
this can be done with lots of images in one run.
i converted your three example images with 'xnConvert' (https://www.xnview.com/en/xnconvert//) – it doubled their size. hopefully this is not a problem.
