Let me try again to explain, this time in more detail.  amd64 with 8 gigs 
ram should handle it (especially with swap, tho pan can take a lot of 
memory, gigs, on large groups so you may wish to quit it as soon as 
you've taken the snap if you track such groups) unless it's WAY huge or 
you're using 10-bit-plus color-channels.


1. Take the pan window and slide it to the edge/corner of the screen, so 
only a bit is showing and it's mostly off-screen.

2. Grab the side/corner of the window and drag it larger.

3. If necessary, repeat.  Note that I've done this with other windows for 
other reasons, and it's possible using this method and repeating the drag-
window-to-corner, drag-window-edge-to-enlarge, to enlarge windows to 3x 
the screen size or more in either/both width/height.

4. Once you get it approximately big enough (or before you start's 
probably easier as pan won't have to calculate sizes for all three 
panes), you will likely either have to switch from paned to tabbed mode 
(if like me you normally use paned mode), or simply turn off all panes 
but body, thus leaving more room for the image display within the huge 
window.

5. Once the window's big enough to show full-res, even tho it's not all 
on-screen, use ksnapshot (or whatever) in window-snap, not screen-snap, 
mode.

6. Save the result to png (or other lossless) as soon as possible and 
copy something else (say a single word of text) to the clipboard to 
release the memory.

7. Open that png and trim off the window edges, etc.  Don't re-save to jpg 
or other lossy format (if you were planning to, maybe you want to keep it 
lossless) until you're done working with it, and save the finished 
product to png before saving to lossy in case the lossy does bad things 
to it, so you can go back to the lossless png and try something else.

8.  If you keep it in png, there's png optimizers that allow you to 
shrink filesize without losing quality.  That's a good thing to run on 
the final png if you intend to keep it png/lossless.


Hope that does it! =:^)
