Bug#495840: gqview doesn't display images larger than 32k horizontal pixels correctly

2008-08-20 Thread Rogier Wolff
Package: gqview
Version: 2.0.1-1
Severity: important


When displaying images with a width greater than 32k pixels gqview
messes up a bit. I'm stitching panoramas and they sometimes have over 
60k horizontal pixels. 

This happens when zoomed out all the way. It doesn't happen when zoomed
in. (I'm suspecting that a signed short is used to count the pixels from
the left of the window or something like that).

Indeed the severity I set sounded a bit hefty, but the description
matched exactly with the situation.

Tested. Results are the same. 

http://prive.bitwizard.nl/DSC_0081-DSC_0112c_lq.jpg is a 5Mbyte sample
image (220 mpixels). (I set jpg quality to 25, so you'll see a lot
of jpg artefacts. Which is to be expected at .2 bits per pixel)
