Breaks a pixel into r, g, b, and a components. More... |
This class in generally quite slow, compared to the engine itself, but useful for general utility functions that don't need to be fast.

Breaks a pixel into r, g, b, and a components. NOTE: alpha is returned in conventional units, 0=transparent, 255=opaque. |

A slow but universal pixel set. NOTE: Uses the alpha channel for 32 bit color. Alpha is in conventional units. |
