Short: Portable C2P and P2C functions Author: Fredrik Wikstrom Uploader: Fredrik Wikstrom <fredrik a500 org> Type: dev/lib Version: 1.1 Architecture: generic Replaces: dev/lib/ppc_c2p_p2c.lha Download: development/fw_c2p_p2c.lha Usage: c2p.h: void chunky2planar (uint8 *chunky, uint16 *planar, uint32 plane_size, uint32 width, uint32 height, uint32 depth); p2c.h: void planar2chunky (uint16 *planar, uint32 plane_size, uint8 *chunky, uint32 width, uint32 height, uint32 depth); Usage of functions should be pretty straight forward. Planar data must be non- interleaved with each plane following directly after the previous one. All depths 1-8 are supported. Width must be a multiple of 16 pixels. For examples on how to use these functions in a program see the CDXLPlay (Source/cdxlplay.c) and/or SRec (Source/formats/cdxl.c) source code that can be downloaded from OS4Depot/Aminet. Compiling: To compile PPC assembler versions: cd ppc make To compile generic C versions: cd generic make Changes: 1.1 (19-Nov-2009) - Added generic C versions 1.0 (11-Nov-2009) - First released version
