Bug ID: 135910
Summary: Transparent objects either possess outlines when none
are defined or are completely opaque, depending on
export PNG options
Product: LibreOffice
Version: 7.1.0.0.alpha0+ Master
Hardware: x86-64 (AMD64)
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Draw
Assignee: libreoffice-bugs at lists.freedesktop.org
Reporter: mwtjunkmail at gmail.com
Description:
Exporting to PNG an ODF's drawing slide with transparent objects leaves those
transparent objects with either a gray/white border around them when no border
was selected, or leaves the transparent objects completely opaque.
Which occurs depends on the output type. If "selection only" is selected, the
transparent objects are opaque.
If one exports the entire slide's contents, the transparent objects are
transparent, but bordered when they should be.
Steps to Reproduce:
1. Launch Draw
2. Insert a picture
3. Draw a shape over the picture
4. Set the shape's border to None
5. Set the shape's transparency to 100% (I also set its color to black)
6. Export the slide either as:
6a. The entire slide
6b. The selected objects only (in this case, all objects were selected).
Actual Results:
When exporting the entire slide, a gray/white border appears around the
transparent object.
When exporting the slide with the "Selection" option checked on the export
dialog box, the transparent objects appear opaque in the final output.
Expected Results:
Regardless of export method, the transparent object should appear transparent,
and should not have border artifacts if a border of None was selected for the
transparent object.
Reproducible: Always
User Profile Reset: No
Additional Info:
Skia rendering selected with anti-aliasing.
