Wrong conversion for Pentax K-5 DNG #60

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Open a DNG file created by a Pentax K-5

What is the expected output? What do you see instead?
Suppose to open a landscape photo: the last (right most) 10 (approx) colums of 
pixel have copletely wrong color, producing a pink line on the photo.

What version of the product are you using? On what operating system?
2011-11-27 (from AUR), on Archlinux 64bit

Please provide any additional information below.
The pink line persists on the output jpeg.
Open the same file with UFRaw 0.18 leads no error.

Confirmed. The garbled columns seem to be additional columns. Photivo produces 
4992×3284 pixels from your example file while standalone dcraw 4950×3284. 
Visually the non-broken area seems to be exactly the same. So you should be 
safe (i.e. not losing any usable image area) with simply cropping the garbled 
columns. It’s definitely a bug, though.

For the record: Bug was introduced by the recent dcraw update to 1.445 (9.11). 
Standalone dcraw 1.445 works as expected.
