directory contents: convert.c image converter words (interleave / deinterleave) program.c libtile program interfacing words.c some more image processing code written in C some notes on formats. bitmap/*// are standard bitmap files, defined by other languages and conventions. image//// are images in internal pf format. the main format is s16: a signed 16bit / component high resolution planar format. s8 is the less well supported 8 bit version. there is room for other formats, but that feature is not well supported. image/YCrCb// is the legacy pdp format, not very well supported either. platform independence is handled through different header files implementing pixel ops using the different vector extensions (mmx, altivec, ...). this is former libtile, without the tile part.
