|
||||
*
|
||||
* FreeTypeGX is a wrapper class for libFreeType which renders a compiled FreeType parsable font into a GX texture for Wii homebrew development.
|
||||
* <br>
|
||||
* FreeTypeGX is written in C++ and makes use of a selectable pre-buffered or buffer-on-demand methodology to allow fast and efficient printing of text to the EFB.
|
||||
* <p>
|
||||
* This library was developed in-full by Armin Tamzarian with the support of developers in \#wiibrew on EFnet.
|
||||
*
|
||||
* \section sec_installation_source Installation (Source Code)

||||
*

||||
* -# Ensure that you have the <a href = "http://www.tehskeen.com/forums/showthread.php?t=9404">libFreeType</a> Wii library installed in your development environment with the library added to your Makefile where appropriate.

* \endcode
|
||||
*
|
||||
* \section sec_freetypegx_prerequisites FreeTypeGX Prerequisites
|
||||
*
|
||||
* Before you begin using FreeTypeGX in your project you must ensure that the desired font in compiled into your project. For this example I will assume you are building your project with a Makefile using devKitPro evironment and are attempting to include a font whose filename is rursus_compact_mono.ttf.
|
||||
*
|
||||
* -# Copy the font into a directory which will be processed by the project's Makefile. If you are unsure about where you should place your font just copy the it into your project's source directory.
|
||||
* \n\n
|
||||
* -# Modify the Makefile to convert the font into an object file:
|
||||
* \code
|
||||
* %.ttf.o : %.ttf
|
||||
* @echo $(notdir $<)
|
||||
* $(bin2o)
|
||||
* \endcode
|
||||
* \n
|
||||
* -# Include the font object's generated header file in your source code:
|
||||
* \code
|
||||
* #include "rursus_compact_mono_ttf.h"
|
||||
* \endcode
|
||||
* This header file defines the two variables that you will need for use within your project:
|
||||
* \code
|
||||
* extern const u8 rursus_compact_mono_ttf[]; A pointer to the font buffer within the compiled project.
|
||||
* extern const u32 rursus_compact_mono_ttf_size; The size of the font's buffer in bytes.
|
||||
* \endcode
|
||||
*
|
||||
* \section sec_freetypegx_usage FreeTypeGX Usage
|
||||
*
|
||||
* -# Within the file you included the FreeTypeGX.h header create an instance object of the FreeTypeGX class:
|
||||
* \code
|
||||
* FreeTypeGX *freeTypeGX = new FreeTypeGX();
|
||||
* \endcode
|
||||
* Alternately you can specify a texture format to which you would like to render the font characters. Note that the default value for this parameter is GX_TF_RGBA8.
|
||||
* \code
|
||||
* FreeTypeGX *freeTypeGX = new FreeTypeGX(GX_TF_RGB565);
|
||||
* \endcode
|
||||
* Furthermore, you can also specify a vertex format index to avoid conflicts with concurrent libraries or other systems. Note that the default value for this parameter is GX_VTXFMT1.
|
||||
* \code
|
||||
* FreeTypeGX *freeTypeGX = new FreeTypeGX(GX_TF_RGB565, GX_VTXFMT1);
|
||||
* \endcode
|
||||
* \n
|
||||
* Currently supported textures are:
|
||||
* \li <i>GX_TF_I4</i>
|
||||
* \li <i>GX_TF_I8</i>
|
||||
* \li <i>GX_TF_IA4</i>
|
||||
* \li <i>GX_TF_IA8</i>
|
||||
* \li <i>GX_TF_RGB565</i>
|
||||
* \li <i>GX_TF_RGB5A3</i>
|
||||
* \li <i>GX_TF_RGBA8</i>
|
||||
*
|
||||
* \n
|
||||
* -# Using the allocated FreeTypeGX instance object call the loadFont function to load the font from the compiled buffer and specify the desired point size. Note that this function can be called multiple times to load a new:
|
||||
* \code
|
||||
* freeTypeGX->loadFont(rursus_compact_mono_ttf, rursus_compact_mono_ttf_size, 64);
|
||||
* \endcode
|
||||
* Alternately you can specify a flag which will load and cache all available font glyphs immidiately. Note that on large font sets enabling this feature could take a significant amount of time.
|
||||
* \code
|
||||

|

*
|
||||
* 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.
|
||||
*
|
||||
* \section sec_installation_source Installation (Source Code)
|
||||
*
|
||||
* -# 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
|
||||
* #include "Metaphrasis.h"
|
||||
* \endcode
|
||||
*
|
||||
* \section sec_installation_library Installation (Library)
|
||||
*
|
||||
* -# Extract the Metaphrasis archive.
|
||||
* -# Copy the contents of the <i>lib</i> directory into your <i>devKitPro/libogc</i> directory.
|
||||
* -# Include the Metaphrasis header file in your code using syntax such as the following:
|
||||
* \code
|
||||
* #include "Metaphrasis.h"
|
||||
* \endcode
|
||||
*
|
||||
* \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
|
||||
* \li convertBufferToIA8
|
||||
* \li convertBufferToRGBA8
|
||||
* \li convertBufferToRGB565
|
||||
* \li convertBufferToRGB5A3
