Cut a rectangle out of an NSBezierPath

Question

Is it possible to remove a chunk of NSBezierPath that is defined by an NSRect region within the path?

Answer 1

Absolutely. This is what clipping regions do:

// Save the current clipping region
[NSGraphicsContext saveGraphicsState];
NSRect dontDrawThisRect = NSMakeRect(x, y, w, h);
// Either:
NSRectClip(dontDrawThisRect);
// Or (usually for more complex shapes):
//[[NSBezierPath bezierPathWithRect:dontDrawThisRect] addClip];
[myBezierPath fill];    // or stroke, or whatever you do
// Restore the clipping region for further drawing
[NSGraphicsContext restoreGraphicsState];
