Detailed Description

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

The MS RLE decoder outputs PAL8 colorspace data.

Note that this decoder expects the palette colors from the end of the BITMAPINFO header passed through palctrl.
