Thanks for the patch, Jonathan. I just came back from a vacation and am still catching up with everything. From a quick look at the patch, this looks good, I'll spend more time as soon as possible.

In the meantime, could you please attach (or send me directly) an image with such a makernote?

#3 Updated by Jonathan Kollasch over 5 years ago

Bug #758 and #759 also have Pentax DNG files attached (from Pentax K-x cameras).

#4 Updated by Andreas Huggel over 5 years ago

Checked-in the patch and made a small change to actually decode the makernote tags using group PentaxDng rather than Pentax (r2697).
What remains is to update preview.cpp so that the thumbnail image in the makernote is recognized again and test writing such a makernote.
