9 Edge Detection Methods

A dedicated Edge Detection tool provides nine unique ways to isolate image edges, ranging from the well-known unidirectional Prewitt and Sobel convolutions, to two methods unique to PhotoDemon. Helpful descriptions of each technique are provided on-dialog.

Like all PhotoDemon tools, a dedicated command bar allows you to save and load custom presets, randomize parameters, and reset to default values. Last-used settings are automatically saved and restored, and all changes provide a real-time preview (no click or mouse button release required).
