Batch Script

Report · Jan 23, 2022

Hi,
New to scripting.
2 folders with 160 images in each.
Images will be jpeg's.

Folder 1 Images are named ... 'take_001_cam_001' ... to ... 'take _001_cam_160'
Folder 2 images named take ...'take_002_cam_001' ... to ... 'take _002_cam_160'
I want to take the first image from each folder and place as 2 x layers, do a 50% opacity (possibly input the value as an input variable) on the top layer and save the image to a new folder.
The naming of new files in the new folder could be 'proc_cam_001' to 'proc_001_cam_160'
Repeat with the second image from each folder and continue until end, that is 160 images in the new folder.

Make sense? Thanks in advance:)

As a start, you can find existing scripts to do most of what you want:

Then there will be specifics to your requirements added as required.

This version uses a simple prompt input to enter in the opacity value rather than using a fixed 50% value:

Mr Marsh,

You are a legend!

Thank you so much.
Works just as expected.

Your welcome. Thanks for the kind words and feedback.

Hi again Stephen,

You were very kind to create a script for me.

Essentially, to open files in a folder and blend togeter.
Would it be difficult for you to 'screen' 2 layers together?

Just changing the upper layer to screen blend mode with no user interaction? What about opacity as in the previous scripts?

Report · Jul 02, 2022

For now, just aq screen on the top layer:)

No opacity change required.

Report · Jul 02, 2022

In the first script without the prompt, simply change the following line from:

 // Change the upper layer to 50% opacity
                doc.activeLayer.opacity = 50;

To:

 // Change the upper layer to screen blend mode
                doc.activeLayer.blendMode = BlendMode.SCREEN;
