1. Extract the Metaphrasis archive.

1. Extract the Metaphrasis archive.
2. Copy the contents of the lib directory into your devKitPro/libogc directory.
3. Include the Metaphrasis header file in your code using syntax such as the following:

• Create a buffer full of 32-bit RGBA values noting both the pixel height and width of the buffer.
• Call one of the many conversion routines from within your code. (Note: All methods within the Metaphrasis class are static and thus no class instance need be allocated)
• uint32_t* rgba8Buffer = Metaphrasis::convertBufferToRGBA8(rgbaBuffer, bufferWidth, bufferHeight);
• Free your temporary RGBA value buffer if you no longer need said values.

Currently supported conversion routines are as follows:

• convertBufferToI4
• convertBufferToI8
• convertBufferToIA4
• convertBufferToIA8
• convertBufferToRGBA8
• convertBufferToRGB565
• convertBufferToRGB5A3
