I was trying to come up with an action to do the following:
Take a pair of pixel rows from an image, paste it in a new image, go on to the next image in a folder, take another pair of rows and past them below the previously placed rows on the new file, etc.
For example:
Copy row 500 and 501 from imageone.jpg
Paste them on composite.jpg as rows 1 and 2
Copy row 500 and 501 from imagetwo.jpg
Paste them on composite.jpg as rows 3 and 4
For hundreds of images.
I think instead of an action/batch combo this would be better addressed through scripting. On the other hand, I know almost nothing about scripting. Someone feel like lending a hand? Either out of the kindness of your heart, or perhaps even some sort of financial incentive…
