Is Batch Straighten sheet music image files not possible in cs2?

I have an ongoing need to straighten sheet music images in pdf and png files. I can switch between the two formats easily, so that is not a problem. I need to assure that at least one set of staff lines is horizontally straight in each of hundreds of whole page images.

For all my attempts, I have about come to the conclusion that Adobe Photoshop cs2 simply cannot do this in batch mode. As a final measure, I’d like to ask the more experienced folks if this is indeed the case.

The crop and straighten tool doesn’t seem to support whole page mode in a batch operation. Holding the Alt key down while *manually* selecting the crop and straighten procedure does seem to work for a whole page; but I don’t see any way to embed the Alt key in the action. I think it just finds the first image and uses the straighten function to correct the whole page based on that. That would be ok, though, if only I could do this for a batch of files.

Is there possibly a way to reconstruct the individual straightened images, resulting from the crop and straighten, so that the whole page is recovered in an overall straightened form? I would then need to get rid of all of the intermediate images, and save only the straighted composite image, somehow.

For all the power Adobe Photoshop cs2 seems to have, it just seems like this is something that would be within it’s realm of features. It just doesn’t seem so, for now. If you know how to do this, would you mind telling me how it could be done? Thank you.

Couple Ideas, a template that’s already straight.
Or the transform for entire page.
Guide lines to define horizontal plane.

I have CS1 so not sure quite what you are doing, but could you do this operation with 2 batch files?
Assuming the images all need straightening to the same degree!! you could have one action that uses the measure tool, and another to crop the resultant images?

Since some of the source images are from my scanner, and some of them are from the net, the image orientation is not consistent. Usually, the angle from horizontal is less than about 2 degrees, but varies page by page.

I don’t see how a template could work in this case. The idea sounds interesting, if I understand what you are suggesting. I guess the idea would be to take a straight line from a template, and somehow determine how the source image is offset from that. using the resulting angle as the rotation amount. Could you give me a little more detail on how that would actually be implemented?

Husky – there is a simpler way to level a picture! especially one with lines already on it which need to be level!
If you go to the eyedrop tool – expand it and select the measure tool, then draw a line out with the measure tool along one of the musical lines so that they are parallel, then go to image – rotate canvas – arbitrary – you will find the PS has already defined the degree of alteration required, accept that and click on OK.

And just how would that work in batch if each image needs a different rotation?…

HOWTO:

4 there’s a little ramp tool at the top now. in the box it may be empty. enter a number and with the mouse wheel, turn the ramp numbers until the image is straight.

It has already been concluded that batch handling would not work! unless of course you have an answer?

This is precisely the way I have been doing it. Well, actually, I use the tool in parallel to a line only in the sense that it actually overlays the line! That is the best way to know that you are indeed on the line.

There are plenty of horizontal lines in sheet music. It just seems unfortunate that there isn’t some trick way to identify one of the many staff lines in an image to use as a basis for straightening the image in total — which would then be something that could be done in a batch process..
