GRRLIB is a C/C++ 2D 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.

As of v4.1.0, 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'.

There are currently 130 applications using GRRLIB.

Help can be found on the forum or in #grrlib on EFnet.

Update History

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
• Alpha compositor function added
• 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 ...)
• add void GRRLIB_InitTileSet(struct GRRLIB_texImg *tex, unsigned int tilew, unsigned int tileh, unsigned int tilestart);
• GRRLIB_DrawImg recoded for simpler use
• GRRLIB_DrawTile recoded for simpler use
• InitVideo() and GRRLIB_Start() merge into GRRLIB_Init().
• add GRRLIB_PtInRect, GRRLIB_RectInRect and GRRLIB_RectOnRect. (to detect hot zone)
• GRRLIB_GetPixelFromtexImg and GRRLIB_SetPixelTotexImg (to directly read/write in texture)
• GRRLIB_CreateEmptyTexture and GRRLIB_FlushTex
• New Bitmap FX
• add GRRLIB_Exit to free the memory allocated by GRRLIB
