the following script which groups everything on the card, gets a

on importGroupSnapshot snapName,myRect
repeat with C=1 to number of controls
   set the selected of control C to true

group
import snapshot from rectangle myRect of last grp
set the name of last img to snapName
select last group
ungroup
select empty
choose the browse tool
end importGroupSnapshot


Unless you need the group for other purposes, you can use the card 
object directly.

Ray,

Importing a snapshot from rect uses the computer’s graphic card to generate the 
snapshot image, whereas, importing a snapshot from an object (group, card, 
stack etc.) allows the LC engine to generate the snapshot image.

I’m travelling right now so can’t test so easy, but I’m sure if you can drop 
the ‘from rect’ you should see an improvement.

Greetings - Has anybody had any success importing a snapshot from a stack's

I'm looping through every card in a stack to import a snapshot using something 
like:

   import snapshot from rect myRect of window myWinId

This causes a lot of annoying screen flicker so I'd like to place the stack's 
window off screen, do the importing and then return it on screen.  But doing so 
gives me blank images for the snapshots.

Any suggestions?

Thanks!

Good point Richard. I had tried importing from the stack which didn't 
work so I [wrongly] assumed it also would not work from the card.  But 
it does!  That's even easier.

Importing a Snapshot from a window off screen

[Ray]

Greetings - Has anybody had any success importing a snapshot from a 
stack's window which is offscreen?


I'm looping through every card in a stack to import a snapshot using 
something like:


   import snapshot from rect myRect of window myWinId

This causes a lot of annoying screen flicker so I'd like to place the 
stack's window off screen, do the importing and then return it on 
screen.  But doing so gives me blank images for the snapshots.


Any suggestions?

Thanks!
