Detailed Description

Convert coordinates between world and grid coordinates. In world coordinates, 1.0 = 1 meter, whereas in grid coordinates, 1 = 1 pixel! The conversion from pixels to meters is 1.0 meter = 1 pixel / scale.

Definition at line 40 of file CoordinateConverter.h.

Constructor & Destructor Documentation

karto::CoordinateConverter::CoordinateConverter ( )

inline

Constructs a converter with a scale of 20.0 (conversion: 1 pixel = 0.05 meters)
