Hi all,

does anyone have any reliable code for getting this? Ive found colorAtX, but it is only supported in 10.4 and I need to support back to 10.2, how do you extract the color and alpha data from getPixel? Im using .jpg and .png images if thats important(?)


Thanks.


Yours cheerfully,


	Andrew Bush
