the operating system might be interesting, as i couldn't reproduce it on mac os 15.1.1 |
|
|
Below are the OS details: Edition Windows 11 Home Single Language Version 23H2 Installed on 07-12-2024 OS build 22631.4460 Experience Windows Feature Experience Pack 1000.22700.1047.0 |
|
|
Also ok here on MacOS |
|
|
I can't reproduce in Linux Mint and Scribus 1.6.2 ...but I've seen this (once upon a time) and Scribus wasn't the source of the problem. Unfortunately I don't remember what solved the problem. |
|
|
anyone on windows? |
|

Tested... I can reproduce in Windows 10 and Scribus 1.6.2 Clipboard 1.jpg (86,037 bytes) |

It seems these JPEG files present themselves as CMYK in their headers, but they are in fact using YCCK colorspace, a common method for encoding CMYK data in jpeg files. There is apparently some method around there to detect the issue and automatically fix it, however I currently don't know which method it is. |

Thank you everyone for the responses - is there a way or some filter that we could apply using Python scripts so they load properly. Just to give a little background - these images are used by a publishing company which generates these media and they are used by different users on different applications so i cannot ask them to create another copy as that would double their work. I need to find some solution wherein we are able to handle it in Scribus Any help in this regards would be highly appreciated |

i don't know how to fix the bug (and why it doesn't affect images in an other os than windows…) but as a workaround i would convert the images to another format. (i.e. .tif) |
|
|
It's the libjpeg library and how it treats those image file formats. On Linux and MacOS our binaries use libjpeg-turbo |
|
|
are there any other libraries that we could use in place of this default one? |
|
|
No, changing the default library would require the whole program to be rebuild from scratch. Anyway I added a workaround for these somewhat broken jpeg files so that they can be processed correctly by standard libjpeg. |
