Richmond, this gave me the horrible case of the jitters. The image would shift
positions as I dragged it. I tried locking and unlocking the screen before and
after the sizing and positioning of the image, but apparently when the user is
interacting with the IDE, the screen is going to unlock anyway whenever an idle
hits. Seems there ought to be a way around this, but I don't have the time
right now to troubleshoot it. It is however fairly quick on my Macbook Pro.
Well; I had a horrible case of the jitters after a 9 hour teaching day,
and that code was the result . . . :)

Hello folks,
I am trying to get an image to slide from the middle of the screen either to
the top or the bottom. However, the screen has a perspective, as if you were
looking down a bowling alley, with a vanishing point somewhere above the screen.
To maintain the sense of depth, images 'pushed away' should shrink into the
distance, and ones 'pulled' closer should embiggen. Any suggestions how this
could best be achieved?
The eventual destination of this may well be iPad, so any special
considerations there would be welcome.
Cheers,
David Glasgow

Here's the clunky version:
I made a stack 1024x768 pixels and popped an image right in the middle of it,
and
put this in the script of the image:
on mouseDown
grab me
end mouseDown
on mouseStillDown
set the idleRate to 1
put the item 2 of the loc of me into LOK
if LOK> 0 then
set the width of me to LOK
set the height of me to LOK
end if
set the loc of me to 512, LOK
end mouseStillDown
on mouseUp
set the idleRate to 1
put the item 2 of the loc of me into LOK
if LOK> 0 then
set the width of me to LOK
set the height of me to LOK
end if
set the loc of me to 512, LOK
end mouseUp
certainly is achingly clunky on my P4, 3 GHz, 2 GB RAM running kinkified Ubuntu.
AND, while I'm here, an opportunity for a faintly bi*chy note:
tried to upload the stack to RevOnline with no success
whatsoever.....................
