Detailed Description#

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

This paint device represents a Scalable Vector Graphics (SVG) drawing. Like QPrinter , it is designed as a write-only device that generates output in a specific format.

To write an SVG file, you first need to configure the output by setting the fileName or outputDevice properties. It is usually necessary to specify the size of the drawing by setting the size property, and in some cases where the drawing will be included in another, the viewBox property also needs to be set.

generator = QSvgGenerator()
generator.setFileName(path)
generator.setSize(QSize(200, 200))
generator.setViewBox(QRect(0, 0, 200, 200))
generator.setTitle(tr("SVG Generator Example Drawing"))
generator.setDescription(tr("An SVG drawing created by the SVG Generator "
                            "Example provided with Qt."))

Other meta-data can be specified by setting the title, description and resolution properties.

As with other QPaintDevice subclasses, a QPainter object is used to paint onto an instance of this class:

painter = QPainter()
painter.begin(generator)            ...
painter.end()

Painting is performed in the same way as for any other paint device. However, it is necessary to use the begin() and end() to explicitly begin and end painting on the device.

The SVG Generator Example shows how the same painting commands can be used for painting a widget and writing an SVG file.

class PySide6.QtSvg.QSvgGenerator#

Constructs a new generator using the SVG Tiny 1.2 profile.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property PᅟySide6.QtSvg.QSvgGenerator.description: str#

This property holds the description of the generated SVG drawing.

See also

title

Access functions:
property PᅟySide6.QtSvg.QSvgGenerator.fileName: str#

This property holds the target filename for the generated SVG drawing.

See also

outputDevice

Access functions:
property PᅟySide6.QtSvg.QSvgGenerator.outputDevice: PySide6.QtCore.QIODevice#

This property holds the output device for the generated SVG drawing.

If both output device and file name are specified, the output device will have precedence.

See also

fileName

Access functions:
property PᅟySide6.QtSvg.QSvgGenerator.resolution: int#

This property holds the resolution of the generated output.

The resolution is specified in dots per inch, and is used to calculate the physical size of an SVG drawing.

See also

size viewBox

Access functions:
property PᅟySide6.QtSvg.QSvgGenerator.size: PySide6.QtCore.QSize#

This property holds the size of the generated SVG drawing.

By default this property is set to QSize(-1, -1), which indicates that the generator should not output the width and height attributes of the <svg> element.

Note

It is not possible to change this property while a QPainter is active on the generator.

See also

viewBox resolution

Access functions:
property PᅟySide6.QtSvg.QSvgGenerator.title: str#

This property holds the title of the generated SVG drawing.

See also

description

Access functions:
property PᅟySide6.QtSvg.QSvgGenerator.viewBox: PySide6.QtCore.QRectF#

This property holds the viewBox of the generated SVG drawing.

By default this property is set to QRect(0, 0, -1, -1), which indicates that the generator should not output the viewBox attribute of the <svg> element.

Note

It is not possible to change this property while a QPainter is active on the generator.
