Tasks related to image  processing is generally done via classes like Image, BufferedImage, Canvas, color  and the such. specifically, if you know the special  color of the point, you may get the colors of points of the image and compare them one be one, till the colored point is found.

I don't remember now the exact commands and classes, but I will review it (if necessary) till tomorrow.

PixelGrabber is a nice class too for getting information about the pixels on an image...

Hi, Ketan.
Have you tried to deal with it with the help of some profeesional imaging tools? Did it work? I only have some experience on VB.NET image processing ( http://www.yiigo.com/guides/vbnet/ ). You can also google it and select some professional tools whose way of processing is simple and fast to help you with the related work. Remember to check its free trial package first if possible. I hope you success. Good luck.



Best regards,
