         *            Colour value of pixel to find (in decimal or hex).
         * @param shadeVariation
         *            A number between 0 and 255 to indicate the allowed number

I write a simple java program。You can download AutoItXDemo.zip and import it into eclipse and run it.

The AutoItX contained in AutoItXDemo.zip is, and the output of the code is something like:

point.x = 0, point.y = 45

but when i use AutoItX, invalid memory access error happened.

Might be a bit easier for people to answer if you posted your code.

See my post below. Thanks.
