Access functions:
__init__()
__init__(parent)
Parameters:

parentQObject

Constructs a new document with parent object parent.

close()

Closes the document.

error()
Return type:

Error

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

getAllText(page)
Parameters:

page – int

Return type:

QPdfSelection

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

getSelection(page, start, end)
Parameters:
Return type:

QPdfSelection

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

getSelectionAtIndex(page, startIndex, maxLength)
Parameters:
  • page – int

  • startIndex – int

  • maxLength – int

Return type:

QPdfSelection

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

load(device)
Parameters:

deviceQIODevice

Loads the document contents from device.

load(fileName)
Parameters:

fileName – str

Loads the document contents from fileName.

metaData(field)
Parameters:

fieldMetaDataField

object

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

pageCount()
Return type:

int

Getter of property pageCountᅟ .

pageCountChanged(pageCount)
Parameters:

pageCount – int

Notification signal of property pageCountᅟ .

pageIndexForLabel(label)
Parameters:

label – str

Return type:

int

See also

pageLabel()

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.

pageModel()
Return type:

QAbstractListModel

Getter of property pageModelᅟ .

pageModelChanged()

Notification signal of property pageModelᅟ .

pagePointSize(page)

page – int

Renders the page into a QImage of size imageSize according to the provided renderOptions.

Returns the rendered page or an empty image in case of an error.

Note: If the imageSize does not match the aspect ratio of the page in the PDF document, the page is rendered scaled, so that it covers the complete imageSize.
