TypeFramework library

GRRLIB is a C/C++ 2D/3D graphics library for Wii application developers. It is essentially a wrapper which presents a friendly interface to the Nintendo GX core. With it, coders can quickly and easily start creating graphical applications.

GRRLIB is supplied as a standard C/C++ library (aka. archive) called 'libgrrlib'. Because GRRLIB processes JPEG and PNG images, it requires the installation of the 'libjpeg' and 'libpngu' libraries. 'libpngu', in turn, requires 'libpng' and 'libpng' requires 'libz'. GRRLIB also has FileIO functions to allow real-time loading and saving of graphical data, and thus also requires 'libfat'. GRRLIB also has the possibility to use TrueType fonts, so 'libfreetype' is also required.

There are currently 0 applications using GRRLIB.

  • Documentation improvement

4.1.0 - October 5, 2009

  • Completely new file structure with sub-folders:
   libgrrlib          <- 2D graphics library
   +-- libfat         <- File I/O
   +-- libjpeg        <- JPEG image processor
   +-- libpngu        <- Wii wrapper for libpng
       +-- libpng     <- PNG image processor
           +-- libz   <- Zip (lossless) compression (for PNG compression)
  • Installer for vendor libraries (jpeg, png, pngu)
  • Makefile for GRRLIB
  • Many (all suitable) functions are now inlined
  • Support for the recent changes to libogc

  • Correct use of pointers (no more struct passing)
  • Speed improvement, bug fixing and more...

4.0.0 - March 5, 2009

  • Color format changed for ALL GRRLib functions (now its RGBA) to fit to GX_Color format and use GX_Color1u32
  • GRRLIB_LoadTexture now Auto Detect PNG or JPEG
  • GRRLib introduce a new texture structure (easier to handle texture width, height, etc ...)
