Description Gregor 2015-08-06 14:56:30 UTC
I recently had Linux and LibreOffice installed. Impress is opening the acrobat pdf's and text that is highlighted is covered over by the highlight. The highlight is showing up, but not the text. I am not sure how to respond about the hardware question

Blending test PDF

This highlight is combined with text using multiply blend mode.
But LibreOffice have no support for blending modes.
See attached PDF test file for example.

Remains an issue, the highlights block the underlaying text. As in page 2 of  attachment 117716 [details] extracted here.

Comment 8 V Stuart Foote 2018-12-16 16:31:51 UTC
As an aside, the pdfium based PDF insert does not render the text highlighting into its bitmap.  But it does handle blending correctly when inserting the "Blending test PDF" of attachment 125910 [details]

Would have expected similar handling...

Problem still exists in Version: 7.2.5.2.0+ running on Manjaro Linux:

I retrieved a .PDF file containing yellow-highlighted text, and only the highlighting is visible on the screen, and only uniform gray appears on the b/w-printed page.

Dear Gregor,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
 
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat: https://web.libera.chat/?settings=#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team
