Print File Objects

A print file object represents a file that is created by QuickDraw GX as the data is spooled to disk for printing. A special kind of print file is the portable digital document, which is created by the PDD Maker GX printer driver.

A print file is self-contained. When you open it, you specify a job object that QuickDraw GX sets up to match the characteristics of the job that printed the file. Thus, a print file retains information about the output and formatting printers, its format, paper types, and so on.

The print file object contains the following properties:

• Page count. This property specifies the number of pages in the file.
• Format list. This property specifies the format object for each page.
• Shape list. This property specifies the picture shape object associated with each page.

For information about each of these properties, see the chapter "Advanced Printing Features" in this book.
