Detailed Description

This class implements support for the set of standard page sizes as defined in the Adobe Postscript PPD Standard v4.3. It defines the standard set of page sizes in points, millimeters and inches and ensures these sizes are consistently used. Other size units can be used but will be calculated results and so may not always be consistent. The defined point sizes are always a integer, all other sizes can be fractions of a unit.

The defined size is always in width x height order with no implied page orientation. Note that it is possible for page sizes to be defined where the width is greater than the height, such as Ledger , so you cannot rely on comparing the width and height values to determine page orientation.

For example, A4 is defined by the standard as 210mm x 297mm, 8.27in x 11.69in, or 595pt x 842pt.

You can also define custom page sizes with custom names in any units you want and this unit size will be preserved and used as the base for all other unit size calculations.

When creating a QPageSize using a custom QSize you can choose if you want QPageSize to try match the size to a standard page size. By default QPaperSize uses a FuzzyMatch mode where it will match a given page size to a standard page size if it falls within 3 postscript points of a defined standard size. You can override this to request only an exact match but this is not recommended as conversions between units can easily lose 3 points and result in incorrect page sizes.

A QPageSize instance may also be obtained by querying the supported page sizes for a print device. In this case the localized name returned is that defined by the printer itself. Note that the print device may not support the current default locale language.

The class also provides convenience methods for converting page size IDs to and from various unit sizes.

Unit

Creates a null QPageSize .

Creates a QPageSize of the standard pageSize .

If pageSize is Custom then the resulting QPageSize will not be valid. Use the custom size constructor instead.

Creates a custom page of the given size in units .

If the given size matches a standard PageSizeId , then that page size will be used. Note that if the matchPolicy is FuzzyMatch this may result in the size being adjusted to the standard size. To prevent this happening use a matchPolicy of ExactMatch instead.

If the given size is not a standard PageSizeId then a Custom size will be created. The original unit size will be preserved and used as the base for all other unit size calculations.

If name is null then a custom name will be created in the form “Custom (width x height)” where the size is expressed in units provided.

Due to historic reasons is not the same as the standard Postscript and Windows Executive size, use instead.

The Postscript standard size is different to the Windows DMPAPER_FOLIO size, use the Postscript standard size if needed.

PySide2.QtGui.QPageSize.definitionSize()
Return type

QSizeF

Returns the definition size of the page size.

For a standard page size this will be the size as defined in the relevant standard, i.e. ISO A4 will be defined in millimeters while ANSI Letter will be defined in inches.

For a custom page size this will be the original size used to create the page size object.

If the QPageSize is invalid then the QSizeF will be invalid.

static PySide2.QtGui.QPageSize.definitionSize(pageSizeId)
Parameters

pageSizeIdPageSizeId

Return type

QSizeF

Returns the definition size of the standard pageSizeId .

To obtain the definition units, call definitionUnits() .

PySide2.QtGui.QPageSize.definitionUnits()
Return type

Unit

Returns the definition units of the page size.

For a standard page size this will be the units as defined in the relevant standard, i.e. ISO A4 will be defined in millimeters while ANSI Letter will be defined in inches.

For a custom page size this will be the original units used to create the page size object.

If the QPageSize is invalid then the Unit will be invalid.

Parameters

pageSizeIdPageSizeId

Return type

Unit

Returns the definition units of the standard pageSizeId .

To obtain the definition size, call definitionSize() .

PySide2.QtGui.QPageSize.id()
Return type

PageSizeId

Returns the standard PageSizeId of the page, or Custom .

static PySide2.QtGui.QPageSize.id(pointSize[, matchPolicy=FuzzyMatch])
Parameters
Return type

PageSizeId

Returns the standard PageSizeId of the given pointSize in points using the given matchPolicy .

If using FuzzyMatch then the point size of the PageSizeId returned may not exactly match the pointSize you passed in. You should call sizePoints() using the returned PageSizeId to find out the actual point size of the PageSizeId before using it in any calculations.

static PySide2.QtGui.QPageSize.id(size, units[, matchPolicy=FuzzyMatch])
Parameters
Return type

PageSizeId

Returns the standard PageSizeId of the given size in units using the given matchPolicy .

If using FuzzyMatch then the unit size of the PageSizeId returned may not exactly match the size you passed in. You should call size() using the returned PageSizeId to find out the actual unit size of the PageSizeId before using it in any calculations.

static PySide2.QtGui.QPageSize.id(windowsId)
Parameters

windowsIdint

Return type

PageSizeId

Returns the PageSizeId for the given Windows DMPAPER enum value windowsId .

If there is no matching PageSizeId then Custom is returned.

PySide2.QtGui.QPageSize.isEquivalentTo(other)
Parameters

otherQPageSize

Return type

bool

Returns true if this page is equivalent to the other page, i.e. if the page has the same size regardless of other attributes like name.

PySide2.QtGui.QPageSize.isValid()
Return type

bool

Returns true if this page size is valid.

The page size may be invalid if created with an invalid PageSizeId , or a negative or invalid QSize or QSizeF , or the null constructor.

PySide2.QtGui.QPageSize.key()
Return type

unicode

Returns the unique key of the page size.

By default this is the PPD standard mediaOption keyword for the page size, or the PPD custom format key. If the QPageSize instance was obtained from a print device then this will be the key provided by the print device and may differ from the standard key.

If the QPageSize is invalid then the key will be an empty string.

This key should never be shown to end users, it is an internal key only. For a human-readable name use name() .
