# Detail

`PaperSize` 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, `PaperSize` allows to construct custom paper sizes with arbitrary dimensions.

The `PaperSize` 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.

# Constructors

paperSizeNew

Arguments

:: Maybe String | `name` - a paper size name, or `Nothing`
-> IO PaperSize |

Creates a new `PaperSize` object by parsing a PWG 5101.1-2002 paper name.

If `name` is Nothing, the default paper size is returned, see `paperSizeGetDefault`.

- Available since Gtk+ version 2.10

paperSizeNewFromPpd

Arguments

:: String | `ppdName` - a PPD paper name
-> String | `ppdDisplayName` - the corresponding human-readable name
-> Double | `width` - the paper width, in points
-> Double | `height` - the paper height in points
-> IO PaperSize |

Creates a new `PaperSize` object by using PPD information.

If `ppdName` is not a recognized PPD paper name, `ppdDisplayName`, `width` and `height` are used to construct a custom `PaperSize` object.

- Available since Gtk+ version 2.10

paperSizeNewCustom

Arguments

:: String | `name` - the paper name
-> String | `displayName` - the human-readable name
-> Double | `width` - the paper width, in units of `unit`
-> Double | `height` - the paper height, in units of `unit`
-> Unit | `unit` - the unit for `width` and `height`
-> IO PaperSize |

Creates a new `PaperSize` object with the given parameters.

- Available since Gtk+ version 2.10

# Methods

paperSizeCopy

Arguments

:: PaperSize |
-> IO PaperSize | returns a copy of `other`

Copies an existing `PaperSize`.

- Available since Gtk+ version 2.10

paperSizeIsEqual

Arguments

:: PaperSize |
-> PaperSize | `size2` - another `PaperSize` object
-> IO Bool | returns `True`, if `size1` and `size2` represent the same paper size

Compares two `PaperSize` objects.

- Available since Gtk+ version 2.10

paperSizeGetName

Arguments

:: PaperSize |
-> IO String | returns the name of `size`

Gets the name of the `PaperSize`.

- Available since Gtk+ version 2.10

paperSizeGetDisplayName

Arguments

:: PaperSize |
-> IO String | returns the human-readable name of `size`

Gets the human-readable name of the `PaperSize`.

- Available since Gtk+ version 2.10

paperSizeGetPpdName

Arguments

:: PaperSize |
-> IO (Maybe String) | returns the PPD name of `size`, or `Nothing`

Gets the PPD name of the `PaperSize`, which may be

- Available since Gtk+ version 2.10

paperSizeGetWidth

Arguments

:: PaperSize |
-> Unit | `unit` - the unit for the return value
-> IO Double | returns the paper width

Gets the paper width of the `PaperSize`, in units of `unit`.

- Available since Gtk+ version 2.10

paperSizeGetHeight

Arguments

:: PaperSize |
-> Unit | `unit` - the unit for the return value
-> IO Double | returns the paper height

Gets the paper height of the `PaperSize`, in units of `unit`.

- Available since Gtk+ version 2.10

paperSizeIsCustom

Arguments

:: PaperSize |
-> IO Bool | returns whether `size` is a custom paper size.

Returns `True` if `size` is not a standard paper size.

paperSizeSetSize

Arguments

:: PaperSize |
-> Double | `width` - the new width in units of `unit`
-> Double | `height` - the new height in units of `unit`
-> Unit | `unit` - the unit for `width` and `height`
-> IO () |

Changes the dimensions of a `size` to `width` x `height`.

- Available since Gtk+ version 2.10

paperSizeGetDefaultTopMargin

Arguments

:: PaperSize |
-> Unit | `unit` - the unit for the return value
-> IO Double | returns the default top margin

paperSizeGetDefaultBottomMargin

Arguments

:: PaperSize |
-> Unit | `unit` - the unit for the return value
-> IO Double | returns the default bottom margin

paperSizeGetDefault

Arguments

:: IO String | returns the name of the default paper size.

paperSizeGetPaperSizes

Arguments

:: Bool | `includeCustom` - whether to include custom paper sizes as defined in the page setup dialog
-> IO [PaperSize] |

Creates a list of known paper sizes.
