png file to reproduce
Compressing PNG files with alpha channel get a black background.
Steps to reproduce :
- insert a png file with alpha channel (see example in attachement) into
libreoffice writer (either using the insert menu or drag and drop)
- right-click "compress"
- in the compress dialog box use JPEG compression, then click OK
- image gets compressed with black background
Used to work properly (i.e. get a white background) with previous libreoffice
versions
Same issue with Draw</pre>
