DrawFaceRect() [12/14]

static void DlibFaceLandmarkDetectorExample.OpenCVForUnityUtils.DrawFaceRect ( Mat imgMat, UnityEngine.Rect rect, in Vec4d color, int thickness )

static

Draws a rectangle on the specified image to indicate a detected face region.

Parameters

imgMat	The Mat image on which to draw the rectangle.
rect	The UnityEngine.Rect defining the area to highlight.
color	The Vec4d color of the rectangle border.
thickness	The thickness of the rectangle border.

DrawFaceRect() [13/14]

static void DlibFaceLandmarkDetectorExample.OpenCVForUnityUtils.DrawFaceRect ( Mat imgMat, UnityEngine.Rect rect, in(double v0, double v1, double v2, double v3) color, int thickness )

static

Draws a rectangle on the specified image to indicate a detected face region.

Parameters

imgMat	The Mat image on which to draw the rectangle.
rect	The UnityEngine.Rect defining the area to highlight.
color	The ValueTuple<Double, Double, Double, Double> color of the rectangle border.
thickness	The thickness of the rectangle border.

DrawFaceRect() [14/14]

static void DlibFaceLandmarkDetectorExample.OpenCVForUnityUtils.DrawFaceRect ( Mat imgMat, UnityEngine.Rect rect, Scalar color, int thickness )

static

Draws a rectangle on the specified image to indicate a detected face region.

Parameters

imgMat	The Mat image on which to draw the rectangle.
rect	The UnityEngine.Rect defining the area to highlight.
color	The Scalar color of the rectangle border.
thickness	The thickness of the rectangle border.

SetImage()

static void DlibFaceLandmarkDetectorExample.OpenCVForUnityUtils.SetImage ( FaceLandmarkDetector faceLandmarkDetector, Mat imgMat )

static

Sets the image for the specified FaceLandmarkDetector using a given Mat object.

Parameters

faceLandmarkDetector	An instance of FaceLandmarkDetector that processes the specified image.
imgMat	A Mat object representing the image to set. The matrix must be continuous and valid for processing.

Exceptions

ArgumentNullException	Thrown if faceLandmarkDetector or imgMat is null.
ArgumentException	Thrown if imgMat is not continuous. Ensure imgMat.isContinuous() == true.

This method directly assigns the imgMat data pointer, width, height, and element size to the specified FaceLandmarkDetector. It avoids additional memory allocations by reusing the existing imgMat data.
