Gradient drawing is not supported on ART backend #14

Open mclarenlabs opened 1 month ago

mclarenlabs commented 1 month ago

Code was originally developed with Cairo backend, but gradient drawing is not supported on the ARG backend.

This call

[NSGradient-drawInBezierPath:path angle:xx]

results in an exception.

NSInvalidArgument [ARTGState-drawGradient:fromPoint toPoint:options:] should be overridden by subclass

Workarounds:

  1. remove gradients altogether (they are not used often in this project)
  2. conditionally use gradients if backend is Cairo

This shows up when compiling the project in the NextSpace environment. NextSpace prefers the ART graphics backend.
