Bug ID: 502807
Summary: Show transparency in a pdf file
Classification: Applications
Product: okular
Version: unspecified
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: PDF backend
Assignee: okular-devel at kde.org
Reporter: c1_kde_bugtrack3r at teamchris.info

Sample pdf with transparent background
I would like to have an option in the settings or the toolbar to actually show
transparent parts in a pdf file (like a checkered background like most programs
do).
STEPS TO REPRODUCE
1. Open pdf with a transparent background (see attachment)
OBSERVED RESULT
Transparency in the PDF file is shown as a white background color.
EXPECTED RESULT
Show the transparency using a checkered background (optional setting, the
default should still be white).
SOFTWARE/OS VERSIONS
Linux/KDE Plasma:
KDE Plasma Version: 6.3.4
KDE Frameworks Version: 6.12.0
Qt Version: 6.9.0
ADDITIONAL INFORMATION
Background: I was reviewing a pdf file that was sent to me for printing and the
file had a transparent background so only the text/logo would be printed and
not a white background around it.
Hint: Use gimp to import the file and in the import dialog unclick "Fill
transparent areas with white" to show the transparent background.
