Description carlosjosepita 2019-06-19 17:11:32 UTC
Description:
I exported a document from google drive to odt. I opened it in libreoffice and the embedded images look very blurry both by themselves and in comparison. If I scale them up in libreoffice the original resolution seems to be still there. 

Steps to Reproduce:
1. Take a screenshot of some text
2. Create a google docs document and embed the image
3. Download the google document as an odt document
4. Open the odf in libreoffice writer

Actual Results:
The embedded image is very blurry.

Expected Results:
The embedded image is exactly like the original one.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:
I have a hidpi monitor (3000x2000).

I'm running Ubuntu 19.04.

Comment 4 carlosjosepita 2019-06-19 18:04:13 UTC
If I select "Edit with external tool" in the image context menu, I can scale the image up and down while keeping a very high resolution in the Gnome image viewer. So the exported image is itself ok, there is some problem in the way libreoffice is scaling it.

printscreen from LO 6.4

Looks correct in Version: 6.4.0.0.alpha0+

CPU threads: 4; OS: Linux 4.15; UI render: default; VCL: gtk3; 

Please test with dev version. Please could you test it with
dev version?  You can download it here:

Thank you

Will that replace the stable version or does it install alongside the stable one?

Anyway, I came to believe this is the real issue underlying the problem: https://gitlab.gnome.org/GNOME/gnome-screenshot/issues/41.

That's not to say LO is doing a good scaling job here, but it's a 2x reduction so I can't really blame it. Google docs is doing a better job but on mobile the images still look like cr*p.

You can install it alongside the standard version. I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the master build

I see no difference between stable and dev versions.

I've attached a screenshot comparing Google Docs (above), LO devel (middle), LO stable (below),  the image in LO opened in an external tool (right). I've also attached the document and the image.

Dear carlosjosepita,

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
