Geoff:
Yes, importing one or a few images and then using them on many buttons works
great. You can even resize the images behind the scenes before opening the
cards:
1) Make a stack, import one copy of all the images you would need anywhere
(in this case that stack is called "alphabet")
2) use this handler to set a userProp for each image which is it's original
size expressed not as a rect (which is assumes a given loc) but only as
width,height (could be anywhere)
on mouseUp
repeat with x = 1 to 72
put the width of image x into tWidth
put the height of image x into tHeight
set mySize of image x to tWidth & "," & tHeight
end repeat
end mouseUp
3) In your stack script put:
on resizeImage theRatio theImage
# where theRatio is the size of the image in any instance
set the defaultStack to "alphabet"
# this would be your stack with imported images
set the width of image id theImage to theRatio * item 1 of the mySize of
image id theImage
set the height of image id theImage to theRatio * item 2 of the mySize
of image id theImage
end resizeImage
on restoreImageSize theImage
set the defaultStack to "alphabet"
set the width of image id theImage to item 1 of the mySize of image id
theImage
set the height of image id theImage to item 2 of the mySize of image id
theImage
end restoreImageSize
4) Now in any given context/card apply those image id's to buttons in you
main stack, I set the id's of all my images to 2000 plus whatever in number
order (in this case an alphabet) and then let's say you want your
images/buttons on a given card to be small, in this case, only 17 percent of
the original, then do this:
on preopenCard
repeat with x = 1 to 18
resizeImage .17, (2000+x)
end repeat
end preopenCard
on closeCard
repeat with x = 1 to 18
restoreimagesize (2000+x)
end repeat
# you must do this to make sure you are resize from a baseline size
end closeCard
with the above strategy, I produced a small app that is only 170 K that in
Supercard would have been close to over 1 meg to display the same images
over the same number of instances. incredible.
