Can I limit the area that L_SetBitmapRgnMagicWand() searches ? I have a gray scale image and using L_SetBitmapRgnMagicWand() to find a certain area. I do not want to process the entire image.

Thanks in advance

Tony

Tony,
You can use the L_SetBitmapRgnRect with the L_RGN_SET flag to create a rectangle region that will represent the 'allowed' area, then use the L_SetBitmapRgnMagicWand with L_RGN_AND. This will create a region of the mutual area of both regions.

Thanks, not sure why I did not think of that.
