Enumeration Type Documentation

LPVPatCenterMode

enum LPVPatCenterMode

This enumeration represents the mode of the pattern template center.

Enumerator
LPVPatImageCenter	Use the template image center as pattern center, and the angle is 0.
LPVPatTrainedCenter	Use the trained center as pattern center, and use the angle of pattern features' rotated bounding rectangle as 0 degree.
LPVPatCustomCenter	Use user-specified position as pattern center, and user-specified angle as 0 degree.

LPVPatDrawFlags

enum LPVPatDrawFlags

This enumeration represents the flags to control the pattern drawing behavior.

Enumerator
LPVPatDrawBoundingRect	Draw the bounding rectangle of the pattern
LPVPatDrawCenter	Draw the center point of the pattern
LPVPatDrawFeature	Draw the features of the pattern
LPVPatDrawIndex	Draw the index of the pattern right to its center
LPVPatDrawFeatureLevel0	Draw the features of the pattern in level 0, as a short straight line
LPVPatDrawFeatureLevel1	Draw the features of the pattern in level 1, as a rectangle with direction
LPVPatDrawFeatureLevelAll	Draw the features of the pattern in all levels
LPVPatDrawDefault	Default draw flags, which draws only the center point
LPVPatDrawAll	Draw a pattern with all components
