Description: Microsoft Windows -- most transparencies export fine for PNG if the entire page is exported, but treatment of transparencies when exported objects only produces solid color where transparency is expected. Steps to Reproduce: 1. Launch Microsoft Windows LO Draw 2. Create a new draw document 3. Import a bitmap picture image 4. Place a square or other object with a color fill on top of the image 5. Set the object's transparency to something other than 0. 6. Export as PNG using the "Selection" option. Actual Results: Any portion of a transparent object overlapping a bitmap appears solid. Expected Results: How the page appears in LibreOffice is how it should appear when exported. Again, this problem does not occur when the entire page is exported. Reproducible: Always User Profile Reset: No Additional Info: Version: 7.2.0.0.alpha0+ (x64) Build ID: 4041c68ea59181f1c4774c356809066d2051db41 CPU threads: 8; OS: Windows 10.0 Build 21277; UI render: Skia/Vulkan; VCL: win Locale: en-US (en_US); UI: en-US Calc: CL
Created attachment 168437 [details] full page PNG Export. The output here is very close (acceptably close) to the way the document appears in LO.
Created attachment 168438 [details] Selected objects only exported The portion of the transparent square overlapping the bitmap appears solid. The area of the transparent square outside the bitmap is fine.
Also note that an imported transparent object renders fine, as no work is done on it upon export. It's only objects in LO Draw with a transparency property set other than the default (no transparency) encountering an issue.
Works for me now in Version: 7.2.0.0.alpha0+ (x64) / LibreOffice Community Build ID: 7eb289c49cc7245ef3001a39be0c15d06bbe875b CPU threads: 8; OS: Windows 10.0 Build 21296; UI render: Skia/Raster; VCL: win Locale: en-US (en_US); UI: en-US Calc: CL
