\brief Rendering SVG files with the Qt SVG module
|
|
|
|
Qt SVG provides classes for rendering SVG files. To include the definitions
|
|
of the module's classes, use the following directive:
|
|
|
|
\snippet doc_src_qtsvg.cpp 0
|
|
|
|
To link against the module, add this line to your \l qmake \c
|
|
.pro file:

\section1 Rendering SVG Files
|
|
|
|
Scalable Vector Graphics (SVG) is a language for describing two-dimensional
|
|
graphics and graphical applications in XML. SVG 1.1 is a W3C Recommendation
|
|
and forms the core of the current SVG developments in Qt. SVG 1.2 is the
|
|
specification currently being developed by the \l{SVG Working Group}, and it
|
|
is \l{http://www.w3.org/TR/SVG12/}{available in draft form}. The \l{Mobile
|
|
SVG Profiles} (SVG Basic and SVG Tiny) are aimed at resource-limited devices
|
|
and are part of the 3GPP platform for third generation mobile phones. You
|
|
can read more about SVG at \l{About SVG}.
|
|
|
|
Qt supports the \l{SVG 1.2 Tiny Static Features}{static features} of
|
|
\l{http://www.w3.org/TR/SVGMobile12}{SVG 1.2 Tiny}. ECMA scripts and DOM manipulation are currently not
|
|
supported.
|
|
|
|
SVG drawings can be rendered onto any QPaintDevice subclass. This
|
|
approach gives developers the flexibility to experiment, in order
|
|
to find the best solution for each application.
|
|
|
|
The easiest way to render SVG files is to construct a QSvgWidget and
|
|
load an SVG file using one of the QSvgWidget::load() functions.
|
|
|
|
QSvgRenderer is the class responsible for rendering SVG files for
|
|
QSvgWidget, and it can be used directly to provide SVG support for
|
|
custom widgets.
|
|
To load an SVG file, construct a QSvgRenderer with a file name or the
|
|
contents of a file, or call QSvgRenderer::load() on an existing
|
|
renderer. If the SVG file has been loaded successfully the
|
|
QSvgRenderer::isValid() will return true.
|
|
|
|
Once you have loaded the SVG file successfully, you can render it
|
|
with the QSvgRenderer::render() function. Note that this scheme allows
|
|
you to render SVG files on all paint devices supported by Qt, including
|
|
QWidget, QGLWidget, and QImage. See the \l{SVG Viewer Example}{SVG Viewer}
|
|
example for more details.
