Is there a way to increase the canvas size by a specific amount to pics of different dimensions?

Hi,

 

I have a load of pics of differing sizes that I want to increase in size by 20px all round. Is there an easy way to automate this (ie with an action) or do I need to use a script? It might be worth pointing out that I have very little knowledge of scripting so am hoping that an action will do the job!

 

Any help would be awesome. Thanks.

You saved the file as RTF and not plain text.

 

You just need to record the action using the relative option;

I believe the simplest option is to create an Action to increase the Canvas size, and then you can Batch this will multiple files.

Thanks Kukurykus and Stephen_A_Marsh; the script (once I'd managed to make it!!) worked a treat, and I can't believe how many years I've used PhotoShop but never seen the "Relative" tick box in Canvas Size!! Apparently you can teach an old new tricks! LOL

    Just remember every time you play or run a script or play an action like that editing a document the document canvas size will be increased. Actions that add mats and frames to images often use several such steps. And canvas added to a background layer will had some color.

      That's right. An action, expanding by pixels in Canvas Size, is straightforward. A script is not necessary.

      I’m not in front of a computer, however from memory you should be able to use a relative value to expand the canvas in an action without requiring a script. 

       

      EDIT: Now that I am in front of Photoshop, here is a visual:

       

       

      Keep in mind that adding a uniform relative 20px is the total size, so that would be 10px on each edge.

      function rC(v) {return eval("aD." + v + ".as('px') + UnitValue('20 px')")}
(aD = activeDocument).resizeCanvas(rC('width'), rC('height'))

        Where do I add that text?
