Detailed Description

A static conversion class for transforming RGBA image buffers into verious GX texture formats for Wii homebrew development.

Author:
Armin Tamzarian
Version:
0.1.0
Metaphrasis is a static conversion class for transforming RGBA image buffers into verious GX texture formats for Wii homebrew development. Metaphrasis is written in C++ and makes use of a community standard and newly developed algorithms for conversion of 32-bit RGBA data buffers into various GX texture formats common to both the Gamecube and Wii platforms.
