Merging files together (side by side) in folder Photoshop scripts

Question

I need to do the following thing. Having multiple png files in folder with a naming convention set: 1.png 1_m.png, 2.png 2_m.png (and so on). The png files have the same wid

Answer 1

I would do this with ImageMagick which is available for free for Windows, OSX and Linux - in fact it is installed on most Linux distros anyway.

The crux of it is to use ImageMagick's convert command to append two images side by side, basically like this:

convert left.png right.png +append out.png

So the script looks like this - (nearly half of it is comments):

#!/bin/bash
for i in [0-9]*_m.png; do
    # Deduce name of left image
    left="$i"
    # Deduce name of right image
    right="${i/_m/}"
    # Deduce name of output image
    done="${i/_m/_done}"
    # Merge the little devils
    convert "$left" "$right" +append "$done"
done

If we start with images like this:

and

It will generate this for all pairs:

This script will do what you want. Put all the files in a directory and then run the script using automate batch -> script. It'll find an image without and underscore in the the file-name and then open it's paired name file (with "_m"), put them side by side and save it out with _done added on to the file-name.

//pref pixels app.preferences.rulerUnits = Units.PIXELS;

var srcDoc = app.activeDocument;

// call the current document
var srcDoc = app.activeDocument;

// set original width and height
var imageW = srcDoc.width.value;
var imageH = srcDoc.height.value;

// get the info out of the source doc
var fileName = srcDoc.name;
var docName = fileName.substring(0,fileName.length -4);
var filePath = srcDoc.path.toString();
var fileExt = fileName.substring(fileName.length -4, fileName.length);

var nameCheck = fileName.substring(0,fileName.indexOf("_"));

if (nameCheck <1)
{
   // no underscore so we need to open it's namesake
   // alert(nameCheck)
   var filePair = filePath + "/" + docName + "_m" + fileExt;
   openThisFile(filePair)
   activeDocument.selection.selectAll()
   activeDocument.selection.copy();
