MATLAB commands (Photoshop Extended)
Typing commands in the MATLAB command line lets you connect and disconnect to Photoshop, and generate pixels
viewable in a Photoshop document.
For a list of all MATLAB Photoshop commands, browse the file psfunctionscat.html, available in the MATLAB folder
in the directory where you installed Photoshop. Enter help (command name) at the MATLAB command prompt for
a fuller description of each command, including syntax, arguments, and examples.
Note: All MATLAB commands are supported for Japanese characters. MATLAB for Windows supports a Japanese
language user interface on Japanese language Windows XP systems. MATLAB for Mac OS supports US English only on
Japanese language Mac OS systems. For more information, contact The MathWorks, Inc.
Create a document in MATLAB (Photoshop Extended)
1 In MATLAB, enter psnewdoc.
2 To specify the attributes of the new document, enter one of the following:
• To create a document using the default values, enter psnewdoc() . For information on default values, see below.
• To create a document with a specific width and height, enter psnewdoc(W,H) . The W and H values use the current
units set in the Units & Rulers option in the Photoshop Preferences dialog box. Other document attributes are set
to their default values.
Note: Enter “undefined” as a string to skip input arguments. The default size for a new document is 504 x 360 pixels.
• To create a document and specify attributes, enter psnewdoc(W,H,R,N,M,F,A,B,P) . For information on new
document attributes, see below.
Here is an example code for creating a document and specifying all the attributes in MATLAB:
psnewdoc(10, 10, 72, 'hi', 'cmyk', 'transparent', 2.5, 16, 'U.S. Web Coated (SWOP) v2')
New document attributes and defaults
Entering psnewdoc(W,H,R,N,M,F,A,B,P) creates a document with values for the following attributes:
W Specifies the width of the document using the current units from the Units & Rulers option in the Photoshop
Preferences dialog box. The default width is 504 pixels.
H Specifies the height of the document using the current units in the Units & Rulers panel in the Photoshop Preference
dialog box. The default height is 360.
R Specifies the resolution. The default is 72 ppi.
N Specifies the document name. The default is Untitled-X, where X is the index for new documents.
