[AS] Batch find images with attributes

Question

Hi!
I've done some applescripting with Indesign but scripting photoshop is new to me.
Problem:
Thousands of grayscale images in a folder. Some of them are not adjusted for print so i need to find images that has light values below 5% an dark values above 95% and move those images to another folder for later processing.
Also some of the images are too wide or too high so those should be moved to another folder for later use.
Can this be done with applescripting Photoshop or is there some other ways (application?)to do it?
Any ideas?
thanks
jukka

Answer 1

What kind of file types do you have? AppleScript has access to SIPS via 'Image Events' a GUI-less app this can check some attributes of files without you opening them (no .eps though). For your below 5% above 95% the only method I can think of at the moment would be to open in Photoshop and read the first and last 12-ish items of the histogram. Something like this would tell you if you have pixels in those ranges. Assuming an open grayscale image.
tell application "Adobe Photoshop CS2"
activate
set docRef to the current document
tell docRef
set docWidth to width
set docHeight to height
set docHistogram to histogram of channel "Gray"
set above95 to 0
repeat with i from 1 to 12
set above95 to above95 + (item i of docHistogram)
end repeat
set below5 to 0
repeat with i from 244 to 256
set below5 to below5 + (item i of docHistogram)
end repeat
if (above95 > 0) and (below5 > 0) then
display dialog "NOT OK Image"
else
display dialog "OK Image"
end if
end tell
end tell
