Internal
Class CurvedImage2D can be used to make a crosscut through an image with a dimensionality >= 2. The crosscut is based on a curve defined by a PixelCurve1D object. The curve can be any 1-dim function (e.g. straight line, spline) supported by the Functionals module. The curve must be in one of the main planes of the image as defined by the axes arguments in the constructor.
See class CurvedImage2D for a more detailed description.
See example in CurvedImage2D .

| ) |
Take a curved slice from the given MaskedLattice.
For example, define a spline in the RA-DEC plane and extend it in the FREQ direction. The result is a 2D lattice with axes FREQ and 'spline'.
The PixelCurve1D object defines the curve in one of the planes of the lattice. The arguments axis1 and axis2 define the plane the curve is in. The CLInterpolator2D object defines the interpolation scheme for pixels that are not on grid points. An example is CLIPNearest2D which takes the nearest neighbour. The dimensionality of the CurvedLattice2D is one less than the dimensionality of the given lattice. Two axes (axis1 and axis2) are replaced by the new axis representing the curve. The argument curveAxis defines the axis number of the new axis. It defaults to the last axis. An exception is thrown if the dimensionality of the input lattice is < 2 or if the given axes numbers are too high.

Is the lattice masked? It is if its parent lattice is masked.

| virtual Bool casa::CurvedLattice2D< T >::isPaged | ( | ) | const [virtual] |
| virtual Bool casa::CurvedLattice2D< T >::isWritable | ( | ) | const [virtual] |

| ) | [virtual] |
Handle ocking of the lattice which is delegated to its parent.
It is strongly recommended to use class LatticeLocker to handle lattice locking. It also contains a more detailed explanation of the locking process.
Reimplemented from casa::LatticeBase.
| virtual void casa::CurvedLattice2D< T >::unlock | ( | ) | [virtual] |
Reimplemented from casa::LatticeBase.

Reimplemented from casa::LatticeBase.
| virtual void casa::CurvedLattice2D< T >::resync | ( | ) | [virtual] |
Resynchronize the Lattice object with the lattice file.
This function is only useful if no read-locking is used, ie. if the table lock option is UserNoReadLocking or AutoNoReadLocking. In that cases the table system does not acquire a read-lock, thus does not synchronize itself automatically.
Reimplemented from casa::LatticeBase.
| virtual void casa::CurvedLattice2D< T >::flush | ( | ) | [virtual] |
| virtual void casa::CurvedLattice2D< T >::tempClose | ( | ) | [virtual] |
Close the Lattice temporarily (if it is paged to disk).
It'll be reopened automatically when needed or when reopen is called explicitly.
