\title QtSvg Module

\ingroup modules
\brief The QtSvg module provides classes for displaying the contents of 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}.
\tableofcontents
\section1 SVG Support
Qt supports the \l{SVG 1.2 Tiny Static Features}{static features} of
\l{SVG 1.2 Tiny}. ECMA scripts and DOM manipulation are currently not
supported.
\section1 Configuring the Build Process
Applications that use Qt's SVG classes need to
be configured to be built against the QtSvg module.
To include the definitions of the module's classes, use the
following directive:
\snippet doc/src/snippets/code/doc_src_qtsvg.qdoc 0
To link against the module, add this line to your \l qmake \c
.pro file:
\snippet doc/src/snippets/code/doc_src_qtsvg.qdoc 1
The QtSvg module is part of the \l{Qt Full Framework Edition} and the
\l{Open Source Versions of Qt}.
\section1 Rendering SVG files
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.
