2006.11.24 10:23 "Windows HD Photo - any interest?", by Brad Hards
Not sure if this has been discussed before, but Windows Vista comes with a new image format (previously known as Windows Media Photo, now called HD Photo). Turns out it is really a TIFF-like format, with a unique codec and some special tags. The tags are described in one specification, known as the Feature specification. The codec is described in a different spec, known as the bitstream specification. They are both embedded in a Device Porting Kit (DPK), which you can find at: http://www.microsoft.com/whdc/xps/hdphotodpk.mspx [I used cabextract to get out the content, and then rebuilt the directory structure based on the DPK specification, which is also in the kit] I see three options: 1. Ignore this pseudo TIFF format. 2. Incorporate the format using the codec in the DPK 3. Incorporate the format using an independent implementation. Anyway, I've done a bit of work on this. See attached. This isn't meant to be applied - it is just a start for future work on options 2 or 3, if anyone wants to work on it. Brad
