Thanks for pointing out that.
After clipping the path. Image is drawn inside the cliping region of the path. But the affine transform which I had applied to path is not applied to the image drawing.
i.e, path is rotated, but image is not rotated and drawn.
I got partial success, I have commented the code to scale X and Y for affinetransform. Then did the drawing like this,
[[NSColor redColor] set];
[path stroke];
[affineTransform concat];
[image drawAtPoint:NSZeroPoint fromRect:imageRect operation:NSCompositeSourceOver fraction:1];
This code works fine, i.e, image is also rotade along with the path. As soon as I scale the affine transform, Path stroking appears properly, but the image scales but the rotation is not applied properly.
