[Therion] Resizing or scaling a replacement background image

[Bill Gee]

Hello everyone -

I am not sure how this should be handled, or if it even CAN be handled ...

A few weeks ago we went to a section of a cave where the original sketch 
has some problems.  Rather than resketch the entire section, we took the 
original sketch and made corrections directly on it.

Now I want to update the Therion map.  Six months ago I used the 
original sketch as the background of a .th2 file, then drew as much as I 
could figure out.  Since the update is on the same piece of paper, I 
figured I could just replace the original drawing background with a 
scanned image of the updated sketch.  It did not work.

The new scanned background comes in about 1/5 as big as it needs to be. 
The original elements I drew do not match up, so I cannot draw the new 
stuff on it.

I think the reason is that the original background and the new 
background were scanned at different resolutions.  I did not scan them. 
The old background image is 2550x3300 pixels and the new is 908x1200 pixels.

What do you suggest?  Is there a way to stretch the new background so it 
fits under the existing drawing?

It might be easiest to ask for a rescan.  The new scan might still not 
line up.  Is there a way to shift the background?  I think there is.  I 
have managed to do it a few times by accident.  No idea what keys I hit 
when that happens.  I have to close the .th2 without saving, then open 
and start again.
