Scripting Photoshop

3.1 Photoshop scripting guidelines

Once you are used to thinking of Photoshop as an object oriented environment, as discussed in

Chapter two, you are ready to move on to writing scripts for the application.

The following guidelines will help save debugging time when running Photoshop scripts.

•

Before running scripts make sure Photoshop’s Text Tool is not selected and no dialog boxes

are displayed to avoid script run-time errors.

•

Select documents by name rather than numeric index and set the current document in your

script before working on it. Document numbers do not represent their stacking order.

See

3.5, “Object references” on page 55

for more information.

•

In AppleScript always create your document with a name and later get that document by

name.

-- get the front-most document

set docRef to make new document with properties ¬

{ height:pixels 144, width:pixels 144, resolution:50,¬

name:"My Document"}

•

When working in VB or JavaScript, store the document reference to a newly-created

document to reuse later.

•

When running AppleScripts and two documents are open with the same name, both

documents will be modi

ﬁ

ed when the name is referenced. For example, the following script

would modify the color pro

ﬁ

le of all open documents named “MyDocument.”

tell application "Adobe Photoshop CS"

set color profile kind of document "MyDocument" to none

end tell

3.2 Viewing Photoshop objects, commands and methods

This section shows how to view Photoshop’s objects, commands and properties in AppleScript

and Visual Basic editors. JavaScript is a cross-platform language and therefore does not

include a native script editor.
