    batch odd dimension images to square

    carleq Level 1



      I have lots of images that are all different sizes and more coming.


      I need to create an action that makes these images square in px dimensions, with the new side dim. the dim. of the longest side.


      I need to add canvas (light gray) to the short side.


      I understand actions but not scripting.


      Thanks exceedingly.

          I have created a script which is a Photoshop Plugin which can be downloaded it is one of my scripts included in my crafting actions package. The Plugin Script name is "AspectRatioSelection.jsx" all you need do is record a two step action that uses it.  Step 1 AspectRatioSelection 1:1 centered replace 0 feather. Step 2 menu Image>Image Crop you can batch that action. If you do not want to crop the image you could in the action a new layer fill it with gray then do the selection and delete the square selection to let the image below show through. If you have to add canvas to the short sides as you write you need to write a simple script to add canvas to the short side so both width and height are equal leave the anchor point the center and the have the added canvas  color be gray. If you look at some of the simpler scripts in my package I think you will be able to figure out a how to do it. The script will not be hard to write. If you can not figure it out Photoshop ships with a Plugin called the "ScriptListener" this Plug-in is install and uninstalled to have Photoshop record scripts.  You can install it start Photoshop create a new document and the add canvas to the document then exit Photoshop. Uninstall the plugin then look on your desktop for you will find two Photoshop scrip files one VSB and one Javascript with two steps new document and add canvas.  From the javascript one it should be east to create a javascript function to add canvas.  All your script would need to do is find the current document's longest size and use the function to make both the wdith and height this size..  Use one of my simple scripts as a script template. Photoshop also shaips with some scripting guide PDF files.

            If I understand what you want, set the background color to your light grey then run this script with an open document.


            var savedRuler= app.preferences.rulerUnits;
            app.preferences.rulerUnits = Units.PIXELS;
            var w = app.activeDocument.width;
            var h = app.activeDocument.height;
            if(w>h) app.activeDocument.resizeCanvas (w, w, AnchorPosition.MIDDLECENTER);
            if(w<h) app.activeDocument.resizeCanvas (h, h, AnchorPosition.MIDDLECENTER);
            //if w==h already square
            app.preferences.rulerUnits = savedRuler;

            You should be able to call the script from an action and batch the action to process all your images at once.

                      Could I possible ask you to make an adjustment to your otherwise perfectly working script.

                      My issue is that I have some images that are very low height and big width,

                      Is it possible to adjust the script to make it account for situation where

                      Width is higher that 3/1 ratio the image would be turned 45 degrees.

                      Your help is very much appreciated , that you in advance

                        Michael passed RIP.


                        Honor his memory learn a little for him. It that would be easy to do. After step 2 add:


                        if (app.activeDocument.width / app.activeDocument.height >= 3) { rotate canvas 45;}


                        All you need to do is figure out the { rotate canvas 45 statement;} part and that statement must be before the setting of the w and h var for their values will depend on the  out come of the  if >= 3 rotate thing you add

                            Hi Carleq, I had the same problem with the batch square crop images.

                            I solved it through the action, not the script. I realized the handy photoshop action to make it easy and fast.


                            You can download it here:



                            It cuts square and circle region from the center of your photos.

                            You can work with any source aspect ratios and proportions, and use the batch processing without additional actions from user side.
