Enumeration Type Documentation

◆ LPVContourDrawFlags

enum LPVContourDrawFlags

This enumeration represents the flags to control the contour result's drawing behavior.

Enumerator
LPVContourDrawContour	Draw the contour
LPVContourDrawBoundingRect	Draw the contour's bounding rect
LPVContourCenter	Draw the contour's center point
LPVContourDrawIndex	Draw the index of the contour on its center point
LPVContourDrawDefault	Default draw flags, which draws only the contour
LPVContourDrawAll	Draw a contour result with all components

◆ LPVContourFeatures

enum LPVContourFeatures

This enumeration represents the numeric features of the contour.

Enumerator
LPVContourPositionX	The x-coordinate position of the contour
LPVContourPositionY	The y-coordinate position of the contour
LPVContourAvgMag	Average magnitude of the contour
LPVContourSumMag	Total magnitude of the contour
