Unable to draw to transparent image to dlg:canvas

[dacap]

Hi @MM102, definitely a bug in the GraphicsContext:drawImage() function, but the version with srcRect and dstRect should work if the image (png) is in RGB mode:

onpaint=function(ev)
  local gc = ev.context
  local rc = img_logo.bounds
  gc.blendMode = BlendMode.SRC_OVER
  gc:drawImage(img_logo, rc, Rectangle(0, 0, rc.w, rc.h))
end

@MM102

Also as aside has there been any progress on this issue? New UIImage kind of object to cache offscreen images/textures · Issue #89 · aseprite/api · GitHub
Loading an image introduces a small delay when loading my script so this would be very useful.

No progress about this one yet.
