|
* Metaphrasis is a static conversion class for transforming RGBA image buffers into verious GX texture formats for Wii homebrew development.
|
||||||
|
* <br>
|
||||||
|
* 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.
|
||||||
|
* <p>
|
||||||
|
* This library was developed in-full by Armin Tamzarian with the support of developers in \#wiibrew on EFnet, Chaosteil of libwiisprite, and DrTwox of GRRLIB.

|
*
|

|
* -# Extract the Metaphrasis archive.
|

|
* -# Copy the contents of the <i>src</i> directory into your project's development path.
|
||||||
|
* -# Include the Metaphrasis header file in your code using syntax such as the following:

* \code

|
* -# Extract the Metaphrasis archive.
|

|
* -# Copy the contents of the <i>lib</i> directory into your <i>devKitPro/libogc</i> directory.

* \section sec_usage Usage
|
||||||
|
*
|
||||||
|
* -# 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)
|
||||||
|
* \code
|
||||||
|
* uint32_t* rgba8Buffer = Metaphrasis::convertBufferToRGBA8(rgbaBuffer, bufferWidth, bufferHeight);
|
||||||
|
* \endcode
|
||||||
|
* -# Free your temporary RGBA value buffer if you no longer need said values.
|
||||||
|
*
|
||||||
|
* Currently supported conversion routines are as follows:
|
||||||
|
* \li convertBufferToI4
|
||||||
|
* \li convertBufferToI8
|
||||||
|
* \li convertBufferToIA4
