Bug ID: 160561
Summary: Complete color alteration when importing a 16 bit
Adobe RGB image Include Printing
Product: LibreOffice
Version: 24.2.2.2 release
Hardware: x86-64 (AMD64)
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Draw
Assignee: [email protected]
Reporter: [email protected]
Description:
IT. seems to have problems representing the colors of some images generated
with Krita with 16bit color depths With variable effects depending on the tones
and size of the image (From slight barely perceptible changes to completely
different colors), The change of colors is not only aesthetic but it also
affects printing and saving
-Tested with exported images as well as
JPG as PNG and direct printing
It does not seem to be a problem with the files or krita since the exported
images are seen normally in the image viewer and browser and (tested Chrome and
Firefox Stable) with images generated for months and current
-Page Quality settings are default and bitmap compression disabled with no
graphics card visual improvements
Steps to Reproduce:
1. Start a new document in Writer or Draw (both tested)
2. import or insert an image (preferably generated with krita) a 16 bit depth
image with Adobe RGB as the profile. in jpg or PNG format [Not necessary but
tested with images with physical size of an A4 sheet or more with 300dpi]
3. Compare colors visually with the source image (You can also detect changes
with tools like PowerToys Color Picker)
4. Try to save and export as PDF (Color changed as output)
Actual Results:
Hue change effects usually vary from almost imperceptible to completely
different colors. These altered colors also affect the saving and printing
process, so different images will be obtained even if printed from libreoffice
or from another app.
Expected Results:
The image colors should be respected since compression is not being used and
the images have a color profile present (or failing that, the user should be
notified that a profile is not available or sRGB will be used instead)
Reproducible: Always
User Profile Reset: No
Additional Info:
I have been using Winget as an update source for a few months, so I don't know
if it will be a bug exclusive to the Winget version or the Windows release in
general.
I can provide the original images with which I have tested the bug if necessary
