Dear Anish,
You can call -lockFocus on the image, and then use NSReadPixel().
NSPoint point = NSMakePoint(x, y);
NSColor *colorAtPoint;
[image lockFocus];
colorAtPoint = NSReadPixel(point);
[thumbnail unlockFocus];
Best regards,
Andrew

Can anyone please tell me how to get the pixel value of an image. I
mean to say that the
pixel values should be same for a particular position in the image
irrespective of the how
much the image is zoomed.
thanks in advance,
