◆ monkey_plot_arc()

static nserror monkey_plot_arc	(	const struct redraw_context *	ctx,
		const plot_style_t *	style,
		int	x,
		int	y,
		int	radius,
		int	angle1,
		int	angle2
	)

static

Plots an arc.

plot an arc segment around (x,y), anticlockwise from angle1 to angle2. Angles are measured anticlockwise from horizontal, in degrees.

Parameters

ctx	The current redraw context.
style	Style controlling the arc plot.
x	The x coordinate of the arc.
y	The y coordinate of the arc.
radius	The radius of the arc.
angle1	The start angle of the arc.
angle2	The finish angle of the arc.

Returns: NSERROR_OK on success else error code.

◆ monkey_plot_bitmap()

static nserror monkey_plot_bitmap	(	const struct redraw_context *	ctx,
		struct bitmap *	bitmap,
		int	x,
		int	y,
		int	width,
		int	height,
		colour	bg,
		bitmap_flags_t	flags
	)

static

Plot a bitmap.

Tiled plot of a bitmap image. (x,y) gives the top left coordinate of an explicitly placed tile. From this tile the image can repeat in all four directions – up, down, left and right – to the extents given by the current clip rectangle.

The bitmap_flags say whether to tile in the x and y directions. If not tiling in x or y directions, the single image is plotted. The width and height give the dimensions the image is to be scaled to.

Parameters

ctx	The current redraw context.
bitmap	The bitmap to plot
x	The x coordinate to plot the bitmap
y	The y coordiante to plot the bitmap
width	The width of area to plot the bitmap into
height	The height of area to plot the bitmap into
bg	the background colour to alpha blend into
flags	the flags controlling the type of plot operation

Returns: NSERROR_OK on success else error code.

Parameters

ctx	The current redraw context.
clip	The rectangle to limit all subsequent plot operations within.

	)

static

Plots a circle.

Plot a circle centered on (x,y), which is optionally filled.

Parameters

static

Plots a line.

plot a line from (x0,y0) to (x1,y1). Coordinates are at centre of line width/thickness.

Parameters

Plots a path.

Path plot consisting of cubic Bezier curves. Line and fill colour is controlled by the plot style.

Parameters

ctx	The current redraw context.
pstyle	Style controlling the path plot.
p	elements of path
n	nunber of elements on path
transform	A transform to apply to the path.
