RenderUnit
Rendering size units.
Definition qgis.h:4839
Struct for storing maximum and minimum scales for measurements in map units.
Base class for visual effects which can be applied to QPicture drawings.
A grouped map of multiple QgsProperty objects, each referenced by a integer key value.
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.
Container for settings relating to a text buffer.
Represents a vector layer which manages a vector based data sets.
