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.
