histogram with equivalent processing. Currently looking into it.
Give me a few hours....

Fixed it and sent copies to Jonas and tapir. Perhaps someone can post both the DNG_Analyser and the PEF_Analyser somewhere so anyone can do what testing pleases them.

Found two problems: forgot a pair of brackets in an byte data array address calculation for the Adobe type DNG's and had to move one statement outside a conditional clause in a couple of places for packed byte DNG's as from the K10D. All seems to work fine now.

So who cares as long as it's fixed

@anyone: Just in case you wonder: there are some emails exchanged
between me, Gordon and tapir. It's not like Gordon works in a
vacuum. When the software works with DNG files I hope somebody
having a K10D can jump in and take some test pictures as well.

Actually, they have a choice to generate DNG's or PEF's in camera, as my PEF_Analyser handles compressed PEF's from the K10D as well as large PEF's from the D or packed byte PEF's from the rest. I would think that in a month or so Adobe will release ACR 3.7, which will convert compressed PEF's from the K10D to DNG's.
