Hi all, I searched back through 2005 in the Cocoa Mailing List and didn't see any requests for this.
We need all the points on a line / arc / path on the screen. We need to do hit detection on stroked line, so we must know if the point is valid or not. I thought using CGPathContainsPoint would work, but it must be done on a closed path or it returns true on all points in the test area. I also tried NSBezierPath containsPath: and , but it returned the exact same things as the CGPath functions. Another idea I have, though not sure if it will work, is converting the drawing to NSBitmapImageRep and using colorAtX:y to test for a specific color to test for a point. The downside of this approach is you must test all the points in a bounding box, and could get quite large if our line segment is complicated. I'm surprised I haven't found a convenience method to return all the points in an outline. Any help would be greatly appreciated. - Cody_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
