Function to load graphic swapped out (loaded on demand)
When a document is loaded it takes a lot of time and memory to
load the graphic that are in the documet, so avoid that and just
store the compressed graphic into a temporary file (handeled by
GfxLink) and load when we really need to show the graphic.

GraphicObject cached some attributes from Graphic, but this
attributes now aren't available immediately so this attributes
are removed form GraphicObject and now delegate to the Graphic
itself. GetSizeBytes attribute however was removed as it is
only used in some tests.

GfxLink initial values were moved to the constructor and are
not set in the header file anymore (as it is the recommended
way to do it).

The SdImportTest::testDocumentLayout failed as it looks like the
dump sometimes didn't include the width and height of the null
bitmap (which is set to 32x32) of the FillBitmap in some
situations, but then in other situations it did include this
attributes. With this change the width and height are always
included for the FillBitmap which looks like it is more correct

Dear Telesto,

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
