Description Hossein 2022-04-27 17:16:28 UTC

Description:
Opening some PDF files in LibreOffice Draw leads to the text being unreadable. The reason is the black color of the text and the dark background.

Steps to Reproduce:
1. Open attachment 179479 [details] (Linux_Voice_Munich.pdf) from tdf#179479 in LibreOffice
2. In the settings, go to "LibreOffice > Application Colors > Color Scheme", then choose "LibreOffice Dark" for application colors.

Actual Results:
The text is not readable, because color of the text is black and the background is dark.

Expected Results:
The text should be readable. If dark mode is desired, then the text color should be changed to something bright to make the text readable.


Reproducible: Always


User Profile Reset: No



Additional Info:
Reproduced with 7.3, and also with the latest 7.4 master:

It seems the Automatic colour of the textboxes is not getting applied correctly. If I re-apply automatic from the Sidebar Properties panel's Character section, it becomes white in the dark theme and black in the normal theme. So maybe the description of the report should be changed?

Any suggestion for a new title?

The font colour seems to be imported as Dark Red 2. Can you somehow investigate how this is defined in the PDF file (or not defined)?

Comment 4 V Stuart Foote 2022-11-20 20:10:51 UTC

On initial import (creation of the textboxes) for imported PDF text runs, the 'Automatic' color of characters in the textboxes does not adjust to the fixed color set for document background in Application Colors 'LibreOffice Dark' color theme.

As noted, resolves by selecting the textboxes and reapplying the automatic theme, i.e. select, apply a color from picker, reselect Automatic.

Windows in DE 'Dark' color theme, with LO Application Colors 'LibreOffice Dark' color theme selected
