Member Function Documentation

◆ arrowSettings()

QgsMeshRendererVectorArrowSettings QgsMeshRendererVectorSettings::arrowSettings ( ) const

Returns settings for vector rendered with arrows.

Since: QGIS 3.12

Definition at line 513 of file qgsmeshrenderersettings.cpp.

◆ color()

Definition at line 177 of file qgsmeshrenderersettings.cpp.

◆ filterMin()

double QgsMeshRendererVectorSettings::filterMin ( ) const

Returns filter value for vector magnitudes.

If magnitude of the vector is lower than this value, the vector is not drawn. -1 represents that filtering is not active.

Definition at line 167 of file qgsmeshrenderersettings.cpp.

◆ isOnUserDefinedGrid()

bool QgsMeshRendererVectorSettings::isOnUserDefinedGrid ( ) const

Returns whether vectors are drawn on user-defined grid.

Definition at line 187 of file qgsmeshrenderersettings.cpp.
