Member Function Documentation
| CT_EXPORT TCoordinateTransform * TOrdnanceSurveyProjection::Copy | ( | TResult & | aError | ) | const [virtual] |
Create an exact copy of this object.
Implements CartoType::TCoordinateTransform.
| CT_EXPORT TResult TOrdnanceSurveyProjection::Inverse | ( | const TPoint & | aInput, |
| TPoint & | aOutput | ||
| ) | const [virtual] |
Project a point using the inverse transformation.
Implements CartoType::TCoordinateTransform.
| CT_EXPORT void TOrdnanceSurveyProjection::ProjectHelper | ( | const TPoint & | aInput, |
| double & | aX, | ||
| double & | aY | ||
| ) | const [protected, virtual] |
Project points to double-precision floating point pixels without applying the final transform.
Implements CartoType::TProjectionUsingFloatingPoint.
| CT_EXPORT TResult TOrdnanceSurveyProjection::Read | ( | TDataInputStream & | aInput | ) | [virtual] |
A virtual function to read a projection object from serialized data. Derived classes call this base function then read any data of their own.
Reimplemented from CartoType::TCoordinateTransform.
The documentation for this class was generated from the following files:
- cartotype_mercator.h
- cartotype_mercator.cpp
