## 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.

## Functions

### gtk_paper_size_new ()

    GtkPaperSize *
    gtk_paper_size_new (const gchar *name);

Creates a new GtkPaperSize object by parsing a

PWG 5101.1-2002

paper name.

If `name` is `NULL`, the default paper size is returned, see `gtk_paper_size_get_default()`.

#### Parameters

name | a paper size name, or `NULL`. | [allow-none]

#### Returns

a new GtkPaperSize, use `gtk_paper_size_free()` to free it

Since 2.10

### gtk_paper_size_new_from_ppd ()

    GtkPaperSize *
    gtk_paper_size_new_from_ppd (const gchar *ppd_name,

                                 gdouble height);

Creates a new GtkPaperSize object by using PPD information.

If `ppd_name` is not a recognized PPD paper name, `ppd_display_name` , `width` and `height` are used to construct a custom GtkPaperSize object.

#### Parameters

ppd_name | a PPD paper name |
ppd_display_name | the corresponding human-readable name |
