Detailed Description

Functions for drawing or filling circles.

Function Documentation

n_graphics_draw_circle()

void n_graphics_draw_circle	(	n_GContext *	ctx,
		n_GPoint	p,
		uint16_t	radius
	)

Draws the outline of a circle.

The circle is centered on a point, so it always has an odd diameter.

n_graphics_draw_circle_bounded()

void n_graphics_draw_circle_bounded	(	n_GContext *	ctx,
		n_GPoint	p,
		uint16_t	radius,
		int16_t	minx,
		int16_t	maxx,
		int16_t	miny,
		int16_t	maxy
	)

Draws the outline of a circle within the given bounds.

n_graphics_fill_circle()

void n_graphics_fill_circle	(	n_GContext *	ctx,
		n_GPoint	p,
		uint16_t	radius
	)

Fills a circle.

The circle is centered on a point, so it always has an odd diameter.

n_graphics_fill_circle_bounded()

void n_graphics_fill_circle_bounded	(	n_GContext *	ctx,
		n_GPoint	p,
		uint16_t	radius,
		int16_t	minx,
		int16_t	maxx,
		int16_t	miny,
		int16_t	maxy
	)

Fills a circle within the given bounds.

n_graphics_prv_draw_quarter_circle_bounded()

void n_graphics_prv_draw_quarter_circle_bounded	(	n_GContext *	ctx,
		n_GPoint	p,
		uint16_t	radius,
		uint16_t	width,
		int8_t	x_dir,
		int8_t	y_dir,
		int16_t	minx,
		int16_t	maxx,
		int16_t	miny,
		int16_t	maxy
	)

Fills a quadrant of a circle.

n_graphics_prv_fill_quarter_circle_bounded()

void n_graphics_prv_fill_quarter_circle_bounded	(	n_GContext *	ctx,
		n_GPoint	p,
		uint16_t	radius,
		int8_t	x_dir,
		int8_t	y_dir,
		int16_t	minx,
		int16_t	maxx,
		int16_t	miny,
		int16_t	maxy
	)

Draws the outline of a quadrant of a circle.
