I have scanned a photo using a flatbed scanner. The image of course is a huge image which includes the photo plus all the scanning area (white) of the scanner. How can I auto crop the image just to have the photo for my final image. Is there some coding in C++ for this? Thanks.

You can leave the scanner to do it (if supported), setting:

ImageEnView1.IO.TWainParams.AutoBorderDetection := true;
ImageEnView1.IO.Acquire();

Otherwise you could assign this task to ImageEn (after acquired the image). You can try:

ImageEnView1.Proc.AutoCrop();

or

ImageEnView1.proc.AutoCrop2();

AutoCrop and AutoCrop2 have several options. You can set them to adapt to your images background.
