Overview: Refer to Detecting and Enhancing Edges and Lines.

Remarks

Imposes a spatial filter on the bitmap. Spatial filters are used for operations such as sharpening an image or detecting edges within the image.

This method supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale images and 48 and 64-bit color images is available only in the Document/Medical toolkits.

This method works best with 24-bit, 16-bit, or grayscale bitmaps. If a bitmap uses a color palette, this method matches the new brightness value of each pixel to the nearest color in the existing palette.
