mlk : Hot Summer Month of 2004
probably wanted at one time or another to combine the power of Photoshop’s
tools to those of programming scripts. Adobe has made this possible for
you with the ‘Scripting Plug-in’, a nifty plug-in that allows users
over Photoshop and do what you couldn’t with you mouse and keyboard…
This tool is also aimed at designers which wish to increase the workflow
speed (you'll see example scripts by the end of the tutorial which allow
you to save all your current images, or save each layer to a separate file etc...).
Even though we do use a scripting language, it is not hardcore programming and
designers which hate programming should not be scared of this, the step by step
tutorial will help you create your first simple scripts and you will later be
able to move on to more advanced scripts.
came across scripting when I was given a school yearbook to do; I had text files
containing each student's info, his picture and Photoshop. I searched for a
way to automate the whole process, and came across the Scripting Plug-in; and
the yearbook was done in almost no time!
[An excerpt from the yearbook,
done by the scripting plug-in]
scripting is much more than what actions and batching can do;
for example you can use the ‘if…then’ commands which already
multiplies possibilities… Imagine you have a text database, hundreds of
pictures, and want to dynamically create business cards – seems tough
? Scripting will do it. It is a unique and excellent tool to automate your needs
and save you time, or create something that a human and a mouse would take ages
will, through a series of projects, demonstrate some of the capabilities of
scripting. This tutorial is aimed at intermediate/advanced users who use
Photoshop extensively. I assume you know about batching & actions, and most
of Photoshop already. The tutorial is set this way: a) example of what we
will create. b) full code c) code explanation... So don't worry if at first you
only see a bunch of scripted lines.
All you'll need for that tutorial is a text file editor, Photoshop and to install
the plug-in (it's
already bundled with PS CS but you’ll need to download it if you own Photoshop
7 - instructions below).
I have broken this tutorial into many sections,
start from the beginning if you have never met scripting.
If you have
a version of Photoshop CS, you can skip the downloading instructions below,
since the scripting plug-in is installed with CS by default. The tutorial uses
scripting with Photoshop 7 – some scripting capabilities have been improved
since then, so don’t be alarmed if you CS version can do in two steps
what I’ve scripted in ten :P… And, on a sidenote,
instructions: you can download the plug-in for version 7 of PS on Adobe’s
web site by searching for ‘scripting plug-in’ – the latest
links were here
(for Mac) or here
(for PCs). Installation will create a ‘Scripts’ folder in the ‘Presets’
folder of Photoshop.
recommend making a shortcut to this folder (and the scripting documentation
folder) which you might use often
familiar with scripting: you can now check your scripts; which you can test
by using the menu File>Automate>Scripts (you can try to alt/apple click
in the dialog box to run your script with a debugger)
also recommend recording an action, in which you play your test
script, and binding a key to this action. In this way all you’ll
have to do to test your script is press the magical key.

language. Keep in mind that the same scripts can be written in VBScript and
Applescript (and much more, since you can script more applications and call
them from these scripts, and not in JS) but the syntax is a bit different (check
the doc for changes).
asking questions or quitting in despair because you can do what
you want – READ the doc given with the scripts, although
it’s incomplete in some places, it will give you a good
feel of scripting and is very important for syntax/references/methods
etc… Make sure to check the sample scripts (provided with
the plug-in) and look at their respective codes to see which
method does what… This tutorial is a re-hash of all these
codes, plus extra scripting.
The scripts have not all been tested with Photoshop CS or Mac-based
machines. If you cannot figure out why your scripts don't work;
check the end of the tutorial to contact me, and I will try
to update the scripts as soon as possible !
