Definition at line 1129 of file qgsmarkersymbollayer.h.

◆ layerType()

QString QgsAnimatedMarkerSymbolLayer::layerType ( ) const
overridevirtual

Returns a string that represents this layer type.

Used for serialization. Should match with the string used to register this symbol layer in the registry.

Reimplemented from QgsRasterMarkerSymbolLayer.

Definition at line 3935 of file qgsmarkersymbollayer.cpp.

◆ properties()

QVariantMap QgsAnimatedMarkerSymbolLayer::properties ( ) const
overridevirtual

Should be reimplemented by subclasses to return a string map that contains the configuration information for the symbol layer.

This is used to serialize a symbol layer perstistently.

Definition at line 3940 of file qgsmarkersymbollayer.cpp.

◆ setFrameRate()

void QgsAnimatedMarkerSymbolLayer::setFrameRate ( double  rate)
inline

frameRate()

Definition at line 1122 of file qgsmarkersymbollayer.h.

◆ startRender()

void QgsAnimatedMarkerSymbolLayer::startRender ( QgsSymbolRenderContext context)
overridevirtual

Called before a set of rendering operations commences on the supplied render context.

This is always followed by a call to stopRender() after all rendering operations have been completed.

Subclasses can use this method to prepare for a set of rendering operations, e.g. by pre-evaluating paths or images to render, and performing other one-time optimisations.
