ImageGear for .NET
Edge Map

An edge map is an image that shows where there are changes in contrast to the original image. Where there are no changes, the resulting image is black. The stronger the contrast change, the brighter the resultant image. The different types of edge maps are slight variations of the algorithms used, and produce slightly different results.

This EdgeMap Method performs the edge map operation specified by the Method argument. Processes specified range of channels. Processes color channels only.

This method takes into account the ROI settings of page object, that are accessible via the ImGearRasterPage.ROI Property. By default ROI is set to the entire image.
