Detailed Description

Low-level graphics routines. Not generally recommended for use, but available to anyone who needs some graphics speedup.

Function Documentation

n_graphics_draw_pixel()

void n_graphics_draw_pixel	(	n_GContext *	ctx,
		n_GPoint	p
	)

Sets the color of a single pixel on the canvas to the current line color.

n_graphics_fill_pixel()

void n_graphics_fill_pixel	(	n_GContext *	ctx,
		n_GPoint	p
	)

Sets the color of a single pixel on the canvas to the current fill color.

n_graphics_prv_draw_col()

void n_graphics_prv_draw_col	(	uint8_t *	fb,
		int16_t	x,
		int16_t	top,
		int16_t	bottom,
		int16_t	minx,
		int16_t	maxx,
		int16_t	miny,
		int16_t	maxy,
		uint8_t	fill
	)

Draws a one-pixel column pretty quickly.

n_graphics_prv_draw_row()

void n_graphics_prv_draw_row	(	uint8_t *	fb,
		int16_t	y,
		int16_t	left,
		int16_t	right,
		int16_t	minx,
		int16_t	maxx,
		int16_t	miny,
		int16_t	maxy,
		uint8_t	fill
	)

Draws a one-pixel row very quickly.

n_graphics_set_pixel()

void n_graphics_set_pixel	(	n_GContext *	ctx,
		n_GPoint	p,
		n_GColor	color
	)

Sets the color of a single pixel on the canvas.
