Flood filing an NSImage

  • Subject: Flood filing an NSImage
  • From: Matthew Smith <email@hidden>

Hello,

I'd like to apply some sort of flood fill on a pixel in my NSImage, where it changes that pixel and every one adjacent to it (and adjacent to them etc) to the colour that I am filling so long as all the changed pixels are adjacent to each other and are the same RGB value...

I'm building my image up by combinations of loading images from the disk, creating composite images and drawing various NSBezierPaths and text on it.

I'd rather not recurse through the data structure and manually do the change if I can help it...

Any suggestions would be great,

cheers

Matt Smith
