Description

@Aaron1011 was kind enough to add the ability for rendering test images, we should add some more of these, some of which may have caught recent regressions.

  • Fill styles (gradients, bitmaps, w/ transforms)
  • Line styles (including all linestyle2 options, caps, joins, fills)
  • Color transforms (including <0% and >100% testing premultiplied alpha)
  • Masking (including nested masks, AS masks)
  • Text (static, edit texts, outline and device fonts)
  • Drawing API
  • BitmapData (and associated methods)
  • Blend modes (when implemented)
  • Filters (when implemented)

Contributor guide

Research direction
Examine existing image test infrastructure in the codebase, then add tests for fill styles, line styles, color transforms, masking, text, drawing API, BitmapData, blend modes, and filters as listed in the issue. Follow the pattern set by @Aaron1011's initial test addition.
