Methods

DrawOnImage

Draws various shapes on an image.

CImageData *DrawOnImage(const CImageData *pImageData, CQuadrilateral quads[], int quadsCount, int color=0xFFFF0000, int thickness=1);
CImageData *DrawOnImage(const CImageData *pImageData, CLineSegment lines[], int linesCount, int color=0xFFFF0000, int thickness=1);
CImageData *DrawOnImage(const CImageData *pImageData, CContour contours[], int contoursCount, int color=0xFFFF0000, int thickness=1);
CImageData *DrawOnImage(const CImageData *pImageData, CCorner corners[], int cornersCount, int color=0xFFFF0000, int thickness=1);
CImageData *DrawOnImage(const CImageData *pImageData, CEdge edges[], int edgesCount, int color=0xFFFF0000, int thickness=1);

Parameters

[in] pImageData A pointer to the image data to draw on.

[in] quads[] An array of quadrilaterals to draw on the image.

[in] quadsCount The number of quadrilaterals in the array.

[in] lines[] An array of line segments to draw on the image.

[in] linesCount The number of line segments in the array.

[in] contours[] An array of contours to draw on the image.

[in] contoursCount The number of contours in the array.

[in] corners[] An array of corners to draw on the image.

[in] cornersCount The number of corners in the array.
