Class QfMapToScreen

ClassList > QfMapToScreen

The QfMapToScreen class transform a map point to screen coordinates. The map point CRS is the one from the map settings. Screen point will be automatically updated on map extent changes.

• #include <qfmaptoscreen.h>

Inherits the following classes: QObject
