FilterEdgeMap Method

Description:

Performs the image processing operation specified by the Method argument.

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

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