I have been trying to decode a version 1 PICT file and I have been unable to find a definition for the 'bitData' data type. This type is used inside a PackBitsRect (among other things) and may contain data that has been packed by the PackBits routine. Inside Mac vol 5 (pg 105) gives the definition of a pixData data type, but I don't think that bitData and pixData are quite the same thing. Note #4 on page 104 describes how PICT files version 2 differ from version 1. It is here that they mention the bitData data type. I couldn't find the definition in vol. 1 and I am hoping that someone out there may have it in a technical note (or possibly know it off hand...)! Also, does anybody know the format of data encoded with the PackBits routine. I am writing a non-mac application and I need to decode PICT files (and, therefore, data encoded with PackBits) without using any toolbox routines. Any help would be greatly appreciated!
