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.
