Description

GtkPaperSize handles paper sizes. It uses the standard called "PWG 5101.1-2002 PWG: Standard for Media Standardized Names" to name the paper sizes (and to get the data for the page sizes). In addition to standard paper sizes, GtkPaperSize allows to construct custom paper sizes with arbitrary dimensions.

The GtkPaperSize object stores not only the dimensions (width and height) of a paper size and its name, it also provides default print margins.

Printing support has been added in GTK+ 2.10.
