Package: libgutenprintui2-1
Version: 4.3.99+cvs20050801-1
Severity: normal

For images wider than they are tall, if set up Auto orientation in print
settings dialog, set scaling to PPI, and save settings, when settings
are restored the scaling and positioning may be wrong.
To see an example:
- Create a 500 px wide by 100 px high blank image in Gimp
- Choose File->Print...
- Set page size to letter
- Set the orientation to "Auto".
- Set "scale by" to "ppi"
- Scale to largest image size = minimum PPI (probably about 45 PPI depending on
printer margins)
- Click button to center image horizontally
- Save settings and cancel out of the print dialog.
- Reopen the print dialog
- Settings have change and the scaling is now set to about 60 PPI.
Also, the x&y offsets are different than they were before, the image
is in top left corner of the page.
This appears to be because the first call to do_all_updates() in
src/gutenprintui2 calls set_orientation() before the printable_width and
printable_height globals are set.
I don't know if there is a corresponding bug in libgutenprintui1 and/or
the 4.2.7 code.
Below is a diff of a stopgap fix of the problem. It's an ugly patch, it
just grabs code called later in preview_update() and places it earlier
in the control flow. If someone actually understands gimpprintui2 and
wants to do this right, that would probably be helpful...
