Full code for Crop Photo in ASP.Net

It seems that you want to crop the image so the final image shows only the passport. If that is the case, use LEADTOOLS AutoCropCommand function that automatically trimming the blank spaces from the edge of the scanned image. The following few lines show how you implement it in your project:

RasterCodecs codecs = new RasterCodecs();
codecs.ThrowExceptionsOnInvalidImages = true;
RasterImage image = codecs.Load("C:\temp\clean.tif");
// Prepare the command
AutoCropCommand command = new AutoCropCommand();
//AutoCrop the image with 20 tolerance.
command.Threshold = 20;
command.Run(image);

It also has other image processing functions including (crop, rotate, resize, autocrop). Check the complete list here:
