Detailed Description

Functions that draw on a surface.

This class in generally quite slow, compared to the engine itself, but useful for general utility functions that don't need to be fast.

Member Function Documentation

void KrPainter::BreakPixel	(	int	x,
		int	y,
		KrRGBA *	rgba
	)			[inline]

Breaks a pixel into r, g, b, and a components.

NOTE: alpha is returned in conventional units, 0=transparent, 255=opaque.

void KrPainter::BreakPixel	(	int	x,
		int	y,
		U8 *	r,
		U8 *	g,
		U8 *	b,
		U8 *	a
	)

Breaks a pixel into r, g, b, and a components.

NOTE: alpha is returned in conventional units, 0=transparent, 255=opaque.

void KrPainter::SetPixel	(	int	x,
		int	y,
		const KrRGBA &	color
	)

A slow but universal pixel set.

NOTE: Uses the alpha channel for 32 bit color. Alpha is in conventional units.
