Description

(This is a merge of a couple of issues)

Is your feature request related to a problem? Please describe. Some images have transparency and the transparency is either undesired or the target image format cannot handle transparency. We can give the user more control how these cases are handled.

Describe the solution you'd like

Just like we have a section for preprocessing the size of an image, we could add a section to preprocess the transparency of an image, offering the following options (or more):

  • Choose a background color (#347, #699)
  • Texture Dilation (#735, 1, 2)

Contributor guide

Research direction
Examine the existing size preprocessing section in the codebase (likely in src/components or similar). Review linked issues #347, #699, #735 for additional context on background color and texture dilation. Look at how the size section integrates with the UI and the codec handling. Propose a UI mockup and implementation plan for a transparency preprocessing panel.
