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')
