Member Function Documentation

◆ ProjToXY()

void Maria::Viewport::ProjToXY ( const BasicGeoTypes::PointDXY &  proj_xy,
BasicGeoTypes::PointDXY &  xy 
) const

Convert from projected coordinates to pixel XY coordinates. This transform will convert the input coordinate from projected coordinates, for example UTM, (or even Lon,Lat for an unprojected coordinate system) to pixel coordinates. This transform does not use the IProjector, only the affine transformation matrix.

◆ XYToProj()

void Maria::Viewport::XYToProj ( const BasicGeoTypes::PointDXY &  xy,
BasicGeoTypes::PointDXY &  proj_xy 
) const

Convert from pixel XY to projected coordinates. This transform will convert the input coordinate from pixel coordinates to projected coordinates, for example UTM, (or even Lon,Lat for an unprojected coordinate system). This transform does not use the IProjector, only the affine transformation matrix.
