Crop an selected part of an Image

Hi,

       I was able to display an image on the RasterImageViewer.Now what I need is that when I select a part of the image(rectangle is drawn to select the part of image ) I need only that part to be displayed and everything outside the image to be cropped(dissapeared) so only the part I selected should be left out.

* The example in LEadTools tutorials example trims 10 pixels off of each side of the image.But what I need is that when I select a part of the image and crop(is crop and trim da same thing) it,only the selected part should be left.

** Can I see some sample coding 4 this.

*** The blackout function I have implemented that is the selected part of the image is filled with Black colour works fine.The code was in the tutorial.

eg:

Leadtools.ImageProcessing.FillCommand command = new Leadtools.ImageProcessing.FillCommand();

// Fill the image with black.

command.Color = new Leadtools.RasterColor(Color.Black);

command.Run(tempImage);  

Thanks a lot.

Through email correspondence with the customer using the LEADTOOLS
support address, it turned out that the function they're looking for is
the AutoCropCommand class, which performs automatic cropping of a different-color surrounding area of the image.
