I tried to run a timing test on my OS X system using 1024 X 768 images
I scribbled in:
on mouseUp
put the long seconds into a
get the imageData of image "A"
put the long seconds into b
set the imageData of image "B" to it
put the long seconds into c
put (b-a) && (c-b)
end mouseUp
==>
0.082148 0.370726
on mouseUp
put the long seconds into a
get the text of image "A"
put the long seconds into b
set the text of image "B" to it
put the long seconds into c
put (b-a) && (c-b)
end mouseUp
==>
0.000027 0.085191
I don't know how much I'd trust the first one. For some reason it
didn't work. It made no change to the destination image.
