Scripting Photoshop

Document object

For example, you could use the

Document

object to get the active layer, save the current

document, then copy and paste within the active document or between different documents.

3.8.1 Saving documents and save options

Photoshop scripting support lets you work with various file formats. It is important to note,

however, that the

Open

and

Save

formats are not identical.

Also note that some formats available in scripting require you to install optional file formats.

The optional formats are:

●

Alias PIX

●

Electric Image

●

SGI RGB

●

Wavefront RLA

●

SoftImage

When using the save command there are a number of specifiable options. These options are

grouped by file type in the provided save options classes. Because the type and contents of the

file you are working on affects how it is saved, some of the option values may not always be

applicable. It also means that many of the option values do not have well defined default

values.

The best way to determine what values can or should be used for save is to perform a save

command from the user interface and then copy the value from the options dialog to your

script. You should perform a complete save operation because there can be multiple dialogs

presented before the document is saved. If you cancel one of the save dialogs without

completing the operation you could miss a dialog containing values needed in your script.

There are many objects that allow you to specify how you want to save your document. For

example, to save a file as a JPEG file, you would use the

JPEG save options

(

JPEGSaveOptions/JPEGSaveOptions

) class as shown below.

AS:

tell application "Adobe Photoshop 7.0"

make new document

set myOptions to {class:JPEG save options, ¬

embed color profile:false, format options: standard, ¬

matte: background color matte,}

save current document in file myFile as JPEG with options ¬

myOptions appending no extension without copying

end tell
