Parameters

page: Image to crop.
left: Left border of the new image.
top: Top border of the new image.
width: Width of the new image.
height: Height of the new image.

Remarks

This method processes all channels of the image. It may shift reference point of image's ROI, if it exists, but does not crop it.

ImGearProcessingVerifier.CanApplyCrop method can be called to check whether the operation can be performed.

Example

// Crops 100 pixels off the top of an image.
ImGearProcessing.Crop(igRasterPage, 0, 100, igRasterPage.DIB.Width, igRasterPage.DIB.Height - 100);
