This question is also asked in zh-tw forum.
Opening files with SVG images inside in LibreOffice and saving as ODT files, the file sizes became much more. Then the user found that under the Pictures folder of ODT files, all the SVG files had a copy of PNG format, which made the file size became much more than the original file.
The original files were made by Apache OpenOffice. In AOO it wouldn’t have a PNG copy.
Is this behavior intentional? Would anyone please tell us what it is for? Besides, is there any expert options to control this behavior, i.e., to control if a PNG copy is made or not?
