Abstract base class for annotation items which are drawn over a map.
virtual void renderAnnotation(QgsRenderContext &context, QSizeF size) const =0
Renders the annotation's contents to a target /a context at the specified /a size.
virtual void readXml(const QDomElement &itemElem, const QgsReadWriteContext &context)=0
Restores the annotation's state from a DOM element.

virtual void writeXml(QDomElement &elem, QDomDocument &doc, const QgsReadWriteContext &context) const =0
Writes the annotation state to a DOM element.
The class is used as a container of context for various read/write operations on other objects.
Contains information about the context of a rendering operation.
An annotation which renders the contents of an SVG file.
QString filePath() const
Returns the file path for the source SVG file.
static QgsSvgAnnotation * create()
Returns a new QgsSvgAnnotation object.
