I have written this code a few different ways. Each seems to be equally
inefficient. I am attempting to compare to images, pixel by pixel, and
record the differences.
ON mouseUp pMouseBtnNo
put 0 into c
set the startvalue of scrollbar Progress to 0
set the endvalue of scrollbar Progress to the length of imagedata of
image "Alpha"
put the imagedata of image "Alpha" into idataalpha
put the imagedata of image "Beta" into idatabeta
REPEAT FOR each char myChar in idataalpha
set the thumbposition of scrollbar Progress to c
IF myChar is not char (c) of idatabeta THEN
put c && char (c) of idatabeta & return after hAll
END IF
put c+1 into c
END repeat
put hAll into field "diff"
END mouseUp
It takes many minutes to process a 200x200 image. I want this code to
eventually compare full screen-captures, so if there is any way to speed
it up, I am open for advice.
Take out the progress bar and then see how it does. Setting a progress
indicator on every repeat often takes longer than running the entire
rest of the handler.
If you do need a progress bar, only update it occasionally; for example,
every few hundred iterations:
if c mod 500 = 0 then set the thumbpos of sb "progress" to c
