select several parts of a label sequentially

[colinw68056105]

I have a label that’s 13.5” wide x 7.75” high and I want to automate several 2” wide extractions in 10% increments along the width. I’m doing it manually, but it's messy and I suspect there is probably a better way from which I can create an action that also prompts for dimensions of different size labels. I’d greatly appreciate suggestions and welcome any questions.
Thank you

You might try the slice tool. Right click and and select Divide Slice. Save for web to save the slices individually.

[colinw68056105]

I like the slice tool, but I don't think slices can only be selected within an image--just from side-to-side or top-to-bottom.

If you can do that systemically  manually in Photoshop.  You would most likely can automate your processing using Photoshop scripting. In a Photoshop Scripting you can use logic to calculate the size the 10 extractions need to be. Then create the 10 extraction like you do manually using a programed processor like your manual procedure.  Scripting require programming knowledge which you most likelt do not have.  

You can also use menu  View>New Guide laueout toe setd guides the the extractions.  You may fine the following thread useful. https://community.adobe.com/t5/photoshop/how-to-slice-a-very-large-poster/m-p/10998357?page=1

"I have a label that’s 13.5” wide x 7.75” high and I want to automate several 2” wide extractions in 10% increments along the width."

10% increments would be 1.35" wide.

If you wish to have something that is not based on specific/absolute sizes, then working in relative units of % would be more flexible.

I'm pretty sure that I have a script that can automate splitting an image into layers...

They seem to have a manual way to make their  2" wide extractions in 10%  increments. While 10x2"  is 20" inches  not 13.5". The Op did not state that there are no overlap areas in the extractions.  10x2"  can  equal 13.5" when you have overlapping areas.  I have seen that type of  extracting done for crating large billboard  and wall murals where the extensions are blown up and printed. The print out  pieces can be easily aligned and  glued to the backing board or wall. seams will not be noticeable if the alignment is not perfect. Without overlay alignment must be perfect which is hard to do if you are dealing with large enlargements.  20"-13.5" = 6.5 " overlap  6.5"/9=0.7"  overlaps.

[Stephen Marsh]

Good point, I was obviously thinking of even splits without overlap, so if this is the case something else may be required.

[colinw68056105]

Explaining a little about the project should be helpful. It’s a virtual photography project that is to emulate photographing a cylindrical bottle as it rotates 360 degrees. In the example, 10 frames are required as input to a “spin” app, such as https://www.webrotate360.com/. There are many environmental challenges to photographing 360 spins, such as unintentional malformed bottles, too much glare or reflection, dirt and dust, and imperfect alignment in the scene. The cost of editing images for these kinds of issues often impairs profitability when clients will not budget for it. So, it's virtual photography to the rescue for products that are bottles with labels.

The images that are extracted from a label may be thought of as frames that are to be layered onto an image of a bottle retrieved from Adobe Stock, for example. Each merged image will look slightly different, emulating the bottle turning. There is a little more processing to do such a slight warp of the label, slight light leaks, but these can be included in an Action and applied to all images.

The case for virtual photography really stands out when 36 or 72 or more images are required, particularly for discerning clients that will not accept the kind of faults shown in this image: https://snap36.com/360-gallery/wine-bottle/. (Not my image or work, btw).

Please don’t hesitate to ask any questions or make suggestions.
Thank you for thinking about my post.
