Detailed Description

QT RLE Video Decoder by Mike Melanson (melanson@pcisys.net) For more information about the QT RLE format, visit: http://www.pcisys.net/~melanson/codecs/

The QT RLE decoder has seven modes of operation: 1, 2, 4, 8, 16, 24, and 32 bits per pixel. For modes 1, 2, 4, and 8 the decoder outputs PAL8 colorspace data. 16-bit data yields RGB555 data. 24-bit data is RGB24 and 32-bit data is RGBA32.
