Scripting Photoshop CS3

Advanced Scripting

This section demonstrates how to use the information contained in the previous sections of this chapter to

create scripts that do the following:

●

Configure document preferences.

●

Apply color to text items. In this section, you will also learn how to do the following:

●

Create a reference to an existing document.

●

Create a layer object and make the layer a text layer.

●

Rasterize text so that

wrap

and

blur

processing can be applied to words. In these sections you will also

learn how to do the following:

●

Select and work with a specific area of a layer by creating a selection object.

●

Apply wave and motion blur filters to selected text.

Note:

When you finish the lesson in each of the following sections, save the script you have created in the

lesson. Each lesson builds upon the script created in the previous lesson.

Working with Document Preferences

The sample scripts in this section activate a Photoshop CS3

Application

object and then save the default

configuration settings into variables so that they can be restored later when the script completes. These

are the default configurations you probably set up in the Preferences dialog when you initially installed

and configured Photoshop CS3.

Note:

To view or set the Preferences on Mac OS, choose

Photoshop > Preferences > Units & Rulers

; in

Windows choose

Edit > Preferences > Units & Rulers

Next, the scripts set the following preferences to the following values:

Script Name

Description

Layer Comps to Files.jsx

Saves layer comps as files.

Layer Comps to PDF.jsx

Saves layer comps as a PDF presentation.

Layer Comps to WPG.jsx

Saves layer comps as a Web photo gallery.

Export Layers to Files.jsx

Exports each layer in the document to a separate file.

Script Events Manager.jsx

Enables and disables notifier objects.

Image Processor.jsx

Processes camera raw images into various file formats.

Load Files into Stack.jsx

Loads separate files into an image stack in a single document.

Merge to HDR.jsx

Combines multiple images of the same scene or image, capturing

the dynamic range of a scene in a single High Dynamic Range (HDR)

image.
