** Summary changed:
- REGRESSION: "display foo.jpg" pan screen shows quadruple (4-fold) image
+ "display foo.jpg" pan screen shows quadruple (4-fold) image for files with
exactly 3000 px y resolution
** Description changed:
- If you display an image larger than your screen with imagemagick's
- 'display' command, you get a "Pan Ico" window where you can choose which
- portion of the image you want to have shown in the main window.
+ Wow, this has got to be the strangest bug I have reported, though I've
+ seen some obscure ones before...
- In the current version, the "Pan Ico" window will show a quadruple image
- instead of a single miniature image. What is curious is that if you
- close the "Pan Ico" window (from the X in the corner), a new one will
- immediately be spawned, and _in the new window, a single miniature image
- will correctly be shown_! Something in the creation of this "Pan Ico"
- window seems to not be initialised correctly.
- I believe this regression was introduced with the very latest upgrade to
imagemagick, although I can not be sure. Excerpt from dpkg.log:
- /var/log/dpkg.log.1:2006-11-28 16:41:31 status installed imagemagick
6:6.2.4.5-0.6ubuntu0.4

only the "affected images" (defined below), the "Pan Ico" window will show a
quadruple image instead of a single miniature image. If you close the "Pan Ico"
window (from the X in the corner), a new one will immediately be spawned, and
in that window, a single miniature image will correctly be shown.
- Using Kubuntu Dapper LTS.
+ After some diagnosis, among the files I tested, this bug _only_ happens
+ with files (jpg) that have a vertical resolution of _exactly_ 3000 px.
+ Not with 3008, not with slighly less, not with ones that have over 4000
+ px on the y axis... go figure. I have also tried to eliminate the
+ possibility of the files having some other parameter besides the y
+ resolution in common by resizing an other jpg file in Krita and saving
+ it with 2998, 3000, and 3002 px... and rightly enough, the one with 3000
+ px exhibits this behaviour, and the others do not. ;-)
+
+
+ I first thought this was a regression with the very latest upgrade to
imagemagick, but it has probably been this way since way back when, as it's a
really isolated incident.
+
+ Using Kubuntu Dapper LTS, imagemagick 6:6.2.4.5-0.6ubuntu0.4.
