Description Armin Le Grand 2012-05-30 14:40:54 UTC

ALG: While GIF allows transparency in the export (use file->export with selection) PNG does not allow that despite PNG being able to do so.

Comment 1 Armin Le Grand 2012-05-30 14:42:22 UTC

ALG: Missing is offering a transparency flag in the PNG option dialog for graphic export and needed stuff to use primitive-based mechanisms to get good, alpha-based pixel graphics from any objects (aka primitive sequences). Adding this.

Comment 2 Armin Le Grand 2012-05-30 14:46:38 UTC

ALG: Okay, done. Committed on trunk. Also increased the quality for gif export and other conversions where alpha-based pixel graphics are created.
