MDirection::Types  fromSys,
bool  wrap = true,
String *  error = NULL 
) [static]

Converts the given coordinates between different systems, using the given WorldCanvas and world system (if applicable).

Input world values are expected to have unit RegionShape::UNIT; output world values always have unit RegionShape::UNIT. Methods that have a "wrap" flag will check the sign of the values when converting between different world coordinate systems, and wrap the values to have the same sign. If a String is given, it will be used to record errors when the method returns false.
