Enumerator
POLARITY_DONT_CARE	Don't care about the polarity, use an absolute threshold. Only supported in the SEARCHMODE_OPTIMIZED_SUB SearchMode.
POLARITY_POSITIVE	Find edges from black to white (gradient).
POLARITY_NEGATIVE	Find edges from white to black (negative gradient).

SearchFunction Property

Enumerator
SEARCHFUNCTION_FIRSTEDGE	Finds the first edge within the search area.
SEARCHFUNCTION_ALLEDGES	Finds all edges within the search area.
SEARCHFUNCTION_EDGEPAIR	Finds the left and the right most edges within the search area.
SEARCHFUNCTION_BESTEDGE	Finds the best edge within the search area. Only supported in the SEARCHMODE_OPTIMIZED_SUB SearchMode.

SearchMode

enum SearchMode

Defines the search mode being used in the Execute method.

Supported platforms:

SearchMode Property

Enumerator
SEARCHMODE_THRESHOLD	Uses a simple threshold to find the edges. No subpixeling.
SEARCHMODE_THRESHOLD_SUB	Uses a simple threshold to find the edges with subpixeling.
SEARCHMODE_CONTRAST	Uses the contrast to find the edges. No subpixeling.
SEARCHMODE_CONTRAST_SUB	Uses the contrast to find the edges with subpixeling.
SEARCHMODE_OPTIMIZED_SUB	Uses the 2nd derivation to find the edges with subpixeling. This is the only mode that supports the SEARCHFUNCTION_BESTEDGE SearchFunction.
