Detailed Description

Functions for drawing 2D primitives into a CByteImage using OpenCV.

Deprecated. Use PrimitivesDrawer instead. Only filling of some primitives and PrimitivesDrawerCV::PutText are not yet implemented in PrimitivesDrawer.

void PrimitivesDrawerCV::DrawConvexPolygon	(	CByteImage *	pImage,
		int *	pPoints,
		int	nPoints,
		int	r = `255`,
		int	g = `255`,
		int	b = `255`,

	)

Draws a polygon into a CByteImage.

The provided points must build a polygon in the given order.

If the polygon is to be filled (thickness = -1), then the points must build a convex polygon.

If thickness >= 1, then it is recommended to use PrimitivesDrawer::DrawConvexPolygon(CByteImage*, const Vec2d*, int, int, int, int, int) instead.

Parameters:

[out]	pImage	The target image, the polygon will be drawn in here. Must be of type CByteImage::eGrayScale or CByteImage::eRGB24.
[in]	pPoints	An array of points containing the 2D point coordinates in the following order: x-coordinate 1st point, y-coordinate 1st point, x-coordinate 2nd point, y-coordinate 2nd point, and so on. Must contain 2 * nPoints integer values.
[in]	nPoints	The number of points. Must be >= 2.
[in]	r	The red component (RGB) of the color to be used for drawing. It must be 0 <= r <= 255.
[in]	g	The green component (RGB) of the color to be used for drawing. It must be 0 <= r <= 255.
[in]	b	The blue component (RGB) of the color to be used for drawing. It must be 0 <= r <= 255.
[in]	thickness	If thickness = -1, then the polygon will be filled. Otherwise (thickness >= 1) this parameter specifies the thickness of the lines to be drawn. If thickness >= 1, then the polygon will be closed if the first and last point are not equal.

Draws text into a CByteImage.

Parameters:

[out]	pImage	The target image, the text will be drawn in here. Must be of type CByteImage::eGrayScale or CByteImage::eRGB24.
[in]	pText	The text to be written.
[in]	x	The x-coordinate of the bootem left corner of the text area in the target image.
[in]	y	The y-coordinate of the bottom left corner of the text area in the target image.
[in]	scale_x	The scaling in x direction. Must be > 0. scale_x = 1.0 is a good value to start with.
[in]	scale_y	The scaling in y direction. Must be > 0. scale_y = 1.0 is a good value to start with.
[in]	r	The red component (RGB) of the color to be used for drawing. It must be 0 <= r <= 255.
[in]	g	The green component (RGB) of the color to be used for drawing. It must be 0 <= r <= 255.
[in]	b	The blue component (RGB) of the color to be used for drawing. It must be 0 <= r <= 255.
[in]	thickness	The thickness of the letters. Must be >= 1.
