circle()

void draw::circle	(	int	cx,
		int	cy,
		int	radius = 10,
		int	r = 255,
		int	g = 255,
		int	b = 255,
		int	a = 255
	)

Draws a non filled 2d circle. this's macro of poly()

Parameters

cx,cy	center position of circle (pixels).
radius	radius of circle in pixels.
r,g,b,a	Color of the line to draw.

cross()

void draw::cross	(	int	cx,
		int	cy,
		int	length = 5,
		int	thickness = 1,
		int	r = 255,
		int	g = 255,
		int	b = 255,
		int	a = 255
	)

Draws a cross. this's macro of line()

Parameters

cx,cy	Center Position of cross (pixels).
length	of line in cross shape.
thickness	size of elements.
r,g,b,a	Color of the line to draw.

line()

void draw::line	(	int	x1,
		int	y1,
		int	x2,
		int	y2,
		int	thickness = 1,
		int	r = 255,
		int	g = 255,
		int	b = 255,
		int	a = 255
	)

Draws a 2d line.

In theory both start and end will be included in coloring. BUG: Currently hardware drivers (d3d/opengl) ignore the last pixel (they use the so called "diamond exit rule" for drawing lines).

Parameters

x1,y1	Start screen coordinates of the start of the line in pixels.
x2,y2	End screen coordinates of the start of the line in pixels.
thickness	size of elements.
r,g,b,a	Color of the line to draw.

pixel()

void draw::pixel	(	int	x,
		int	y,
		int	thickness = 1,
		int	r = 255,
		int	g = 255,
		int	b = 255,
		int	a = 255
	)

Draws a pixel.

Parameters

x	The x-position of the pixel.
y	The y-position of the pixel.
thickness	size of elements.
r,g,b,a	Color of the pixel to draw.

plus()

void draw::plus	(	int	cx,
		int	cy,
		int	length = 5,
		int	thickness = 1,
		int	r = 255,
		int	g = 255,
		int	b = 255,
		int	a = 255
	)

Draws a plus. this's macro of line()

Parameters

cx,cy	Center Position of plus (pixels).
length	of line in plus shape.
thickness	size of elements.
r,g,b,a	Color of the line to draw.

poly()

void draw::poly	(	int	cx,
		int	cy,
		int	radius = 10,
		int	vertexCount = 10,
		bool	fill = false,
		int	start_percent = 0,
		int	end_percent = 100,
		const char *	texture_name = 0,
		int	r = 255,
		int	g = 255,
		int	b = 255,
		int	a = 255
	)

Draws a non filled concyclic regular 2d polygon.

This method can be used to draw circles, but also triangles, tetragons, pentagons, hexagons, heptagons, octagons, enneagons, decagons, hendecagons, dodecagon, triskaidecagons, etc. I think you'll got it now. And all this by simply specifying the vertex count. Welcome to the wonders of geometry.

Parameters

cx,cy	Center Position of center of circle (pixels).
radius	Radius of circle in pixels.
vertexCount	Amount of vertices of the polygon. Specify 2 to draw a line, 3 to draw a triangle, 4 for tetragons and a lot (>10) for nearly a circle.
fill	Fill the rectangle with color.
start_percent	start draw polygon percent [0..100], start at bottom center.
end_percent	end draw polygon percent [0..100], end at bottom center.
texture_name	show texture inside polygon, image filename or layername in psd. NOTE: fill must true.
r,g,b,a	Color of the line to draw.

rect()

void draw::rect	(	int	x1,
		int	y1,
		int	x2,
		int	y2,
		int	thickness = 1,
		bool	fill = false,
		int	r = 255,
		int	g = 255,
		int	b = 255,
		int	a = 255
	)

Draws a 2d rectangle.

Parameters

x1,y1	Top-Left position of the rectangle.
x2,y2	Bottom-Right position of the rectangle.
thickness	size of elements.
fill	Fill the rectangle with color.
r,g,b,a	Color of the line to draw.
