RenderUnit
Rendering size units.
Definition: qgis.h:4255
Struct for storing maximum and minimum scales for measurements in map units.
A grouped map of multiple QgsProperty objects, each referenced by a integer key value.
Contains information about the context of a rendering operation.
Container for settings relating to a text shadow.
ShadowPlacement
Placement positions for text shadow.
@ ShadowBuffer
Draw shadow under buffer.
@ ShadowText
Draw shadow under text.
Represents a vector layer which manages a vector based data sets.
double ANALYSIS_EXPORT angle(QgsPoint *p1, QgsPoint *p2, QgsPoint *p3, QgsPoint *p4)
Calculates the angle between two segments (in 2 dimension, z-values are ignored)
