PySide6.QtPdf.QPdfDocument.close()#

Closes the document.

PySide6.QtPdf.QPdfDocument.error()#

Return type:: Error

Returns the type of error if status is Error, or NoError if there is no error.

PySide6.QtPdf.QPdfDocument.getAllText(page)#

Parameters:: page – int
Return type:: PySide6.QtPdf.QPdfSelection

Returns all the text and its bounds on the given page.

PySide6.QtPdf.QPdfDocument.getSelection(page, start, end)#

Parameters:

page – int
start – PySide6.QtCore.QPointF
end – PySide6.QtCore.QPointF

Return type:

PySide6.QtPdf.QPdfSelection

Returns information about the text on the given page that can be found between the given start and end points, if any.

PySide6.QtPdf.QPdfDocument.getSelectionAtIndex(page, startIndex, maxLength)#

Parameters:

page – int
startIndex – int
maxLength – int

Return type:

PySide6.QtPdf.QPdfSelection

Returns information about the text on the given page that can be found beginning at the given startIndex with at most maxLength characters.

PySide6.QtPdf.QPdfDocument.load(device)#

Parameters:: device – PySide6.QtCore.QIODevice

Loads the document contents from device.

PySide6.QtPdf.QPdfDocument.load(fileName)

Parameters:: fileName – str
Return type:: Error

Loads the document contents from fileName.

PySide6.QtPdf.QPdfDocument.metaData(field)#

Parameters:: field – MetaDataField
Return type:: object

Returns the meta data of the document for the given field.

PySide6.QtPdf.QPdfDocument.pageCount()#

Return type:: int

Getter of property pageCount .

PySide6.QtPdf.QPdfDocument.pageCountChanged(pageCount)#

Parameters:: pageCount – int

Notification signal of property pageCount .

PySide6.QtPdf.QPdfDocument.pageIndexForLabel(label)#

Parameters:: label – str
Return type:: int

Returns the index of the page that has the label, or -1 if not found.

See also

pageLabel()

PySide6.QtPdf.QPdfDocument.pageLabel(page)#

Parameters:: page – int
Return type:: str

Returns the page number to be used for display purposes.

For example, a document may have multiple sections with different numbering. Perhaps the preface uses roman numerals, the body starts on page 1, and the appendix starts at A1. Whenever a PDF viewer shows a page number, to avoid confusing the user it should be the same “number” as is printed on the corner of the page, rather than the zero-based page index that we use in APIs (assuming the document author has made the page labels match the printed numbers).

If the document does not have custom page numbering, this function returns page + 1.
