Detailed Description

QPdfWriter generates PDF out of a series of drawing commands using QPainter. The newPage() method can be used to create several pages.

Member Function Documentation

`[explicit]` QPdfWriter::QPdfWriter(const QString &filename)

Constructs a PDF writer that will write the pdf to filename.

`[explicit]` QPdfWriter::QPdfWriter(QIODevice **device*)

Constructs a PDF writer that will write the pdf to device.

`[virtual noexcept]` QPdfWriter::~QPdfWriter()

Destroys the pdf writer.

void QPdfWriter::addFileAttachment(const QString &fileName, const QByteArray &data, const QString &mimeType = QString())

Adds fileName attachment to the PDF with (optional) mimeType. data contains the raw file data to embed into the PDF file.

QString QPdfWriter::creator() const

Returns the creator of the document.

See also setCreator().

QByteArray QPdfWriter::documentXmpMetadata() const

Gets the document metadata, as it was provided with a call to setDocumentXmpMetadata. It will not return the default metadata.

See also setDocumentXmpMetadata().

`[override virtual]` bool QPdfWriter::newPage()

Reimplements: QPagedPaintDevice::newPage().

`[override virtual protected]` QPaintEngine *QPdfWriter::paintEngine() const

Reimplements: QPaintDevice::paintEngine() const.

QPagedPaintDevice::PdfVersion QPdfWriter::pdfVersion() const

Returns the PDF version for this writer. The default is PdfVersion_1_4.

See also setPdfVersion().

int QPdfWriter::resolution() const

Returns the resolution of the PDF in DPI.

See also setResolution().

void QPdfWriter::setCreator(const QString &creator)

Sets the creator of the document to creator.

See also creator().

void QPdfWriter::setDocumentXmpMetadata(const QByteArray &xmpMetadata)

Sets the document metadata. This metadata is not influenced by the setTitle / setCreator methods, so is up to the user to keep it consistent. xmpMetadata contains XML formatted metadata to embed into the PDF file.

See also documentXmpMetadata().

void QPdfWriter::setPdfVersion(QPagedPaintDevice::PdfVersion version)

Sets the PDF version for this writer to version.

If version is the same value as currently set then no change will be made.

See also pdfVersion().

void QPdfWriter::setResolution(int resolution)

Sets the PDF resolution in DPI.

This setting affects the coordinate system as returned by, for example QPainter::viewport().

See also resolution().

void QPdfWriter::setTitle(const QString &title)

Sets the title of the document being created to title.

See also title().

QString QPdfWriter::title() const

Returns the title of the document.

See also setTitle().
