Description: Transparent background when exporting a page with image to PNG Steps to Reproduce: 1. Open Draw 2. Insert a picture 3. File -> Export PNG (probably also with Impress, which might be problematic sheet) Compare with GDI mode Actual Results: Transparent background on Windows, not sure for the other backends. This is a change in behaviour Expected Results: The hard part. For draw this is technically correct. No background. A) It's confusing from what you see is what you get. B) There is no indicator if background being transparent or white. Most editor have a different canvas for transparent Reproducible: Always User Profile Reset: No Additional Info: Somewhere in 7.1
I agree, it is confusing. You have a (visually) white background whether the page background is transparent or white. Many programs like Paint.net, Krita, and others use a checkered white-and-gray pattern to represent transparency. It is ABSOLUTELY desirable to have an exported image from Draw to have a transparent background if the background is set to None.
I agree, the export dialog, where you can tell Size, Compression, Mode, etc., it should have a checkbox: [_] Save Background as visible (rather than transparent) By default, it should be unchecked (save as transparent).
We discussed the topic in the design meeting. Here are the minutes: + reason for the confusion is likely the fact that background color is saved when the full document is exported + don't see Draw as equivalent to Inkscape or the like, -1 for the checkerboard background (Heiko) + also it's not clear how to implement without affecting the document + but we already have provided checkerboard for the SB Gallery + would be nice to have (Stuart) + Export option "[ ] Save Background as visible" (Csongor, Stuart) + rather have a new section *Background* with "[x] Save Transparency" Let's implement this.
