            Bug ID: 139251
           Summary: Black text shadow not rendered correctly in exported
                    gif and  png files.
           Product: LibreOffice
           Version: 7.0.0.3 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Draw
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: Treehaven2010 at hotmail.com

Description:
Black shadow from white text on a blue background is rendered as light grey rgb
206,206,206 (Hex CECECE) when the page is exported as as gif file, and as a
transparent area when the page is exported as as png file. Thw same page
exported jpg file is correctly rendered. 

Checked this was not problem with the program used to examine the files by
opening them again with a different program.

Steps to Reproduce:
1.Open a new Draw document.
2.Create a text box with blue area and white text (Big text makes the problem
easier to see. I used 44pt but even bigger would be good.)
3. Toggle text shadow on while the text box is selected.
4. Export the page as a gif file.
5. Export the page as a png file.
6. Export the page as a jpg file.

6. Examine the exported files with any graphics display program. (I used
paint.net.)




Actual Results:
The black text shadow is correctly rendered in the display.
The gif file will have text shadows in light grey.
The png file will have text shadows which are transparent
The jpg file will have black text shadows. (Correct)

Expected Results:
Exported gif and png files should have had shadows rendered as black, like the
exported jpg file.


Reproducible: Always


User Profile Reset: No



Additional Info:
Tried the same test on my wife's windows laptop which is running LibreOffice
6.3.5.2 and it rendered an exported gif file correctly with black shadows. But
an exported png file had transparerent shadows, as described above.

Tried exporting to pdf and to svg (From 7.0.0.3). Both rendered the shadows
correctly as black.
