I am exporting a screen image of a card to file.
I allow the user to select a filename then save the image using the script
below. I have had to add a 400mS wait in for the save dialogue to vanish
before the snapshot is taken. This works OK, but is there a better way to do
it that guarantees that the save dialogue will be gone first? At the moment
I know 100mS is plenty on my system so I have selected 400mS as margin
ask file "Save Dive/Air Plan image as:" with the DefaultFolder with
filter "JPG File, *.JPG"
put it into UserFileName
if it is not empty then
set the itemdelimiter to "."
if item 2 of UserFileName is empty then
put UserFileName & ".jpg" into UserFileName
wait 400 milliseconds
Put the rect of this stack into MyScreen
export snapshot from rect MyScreen to file UserFileName as JPEG
Answer "Screen saved as" & UserFileName with "OK"
