Detailed Description

template<class T>
class casacore::ImageConcat< T >

Concatenates images along a specified axis.

Prerequisite

Etymology

This is a class designed to concatenate images along a specified axis

Synopsis

This is a class designed to concatenate images along a specified axis. This means you can join them together. E.g., join images of shape [10,20,30] and [10,20,40] into a lattice of shape [10,20,70].

The ImageConcat object does not copy the input images, it just references them. You can use the Lattice<T>::copyData(Lattice<T>) function to fill an output image with the concatenated input images

If you use the putSlice function, be aware that it will change the underlying images if they are writable.

You can also concatenate a lattice to an image.

Example

IPosition shape(2, 10, 20);
PagedImage<Float> im1(shape, CoordinateUtil::defaultCoords2D(),
"tImageConcat_tmp1.img");
im1.set(1.0);
PagedImage<Float> im2(shape, CoordinateUtil::defaultCoords2D(),
"tImageConcat_tmp2.img");
im2.set(2.0);
// Make concatenator for axis 0
ImageConcat<Float> concat(0);
// Relax coordinate constraints
concat.setImage(im1, True);
concat.setImage(im2, True);
// Make output image and mask (if required, which it will be in this case)
PagedImage<Float> im3(concat.shape(), CoordinateUtil::defaultCoords2D(),
"tImageConcat_tmp3.img");
// Copy to output
im3.copyData(concat);

See tImageConcat.cc for more examples.

Motivation

Image concatentation is a useful enduser requirement.

virtual Bool casacore::ImageConcat< T >::doGetMaskSlice ( Array< Bool > &  buffer,

virtual

Do the actual get of the mask data.

The return value is always False, thus the buffer does not reference another array. Generally the user should use function getMaskSlice

Reimplemented from casacore::MaskedLattice< T >.

template<class T>
virtual Bool casacore::ImageConcat< T >::doGetSlice ( Array< T > &  buffer,

virtual

Do the actual get of the data.

virtual void casacore::ImageConcat< T >::doPutSlice ( const Array< T > &  sourceBuffer,

virtual void casacore::ImageConcat< 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.
By default the function does not do anything at all.

Reimplemented from casacore::LatticeBase.

template<class T>
virtual void casacore::ImageConcat< T >::save ( const String fileName) const
virtual

Save the image in file 'image.concat' in a directory with the given name.

An exception is thrown if such a directory or file already exists. It can be opened by ImageOpener::openImage(Concat).

Reimplemented from casacore::LatticeBase.

template<class T>
void casacore::ImageConcat< T >::setCoordinates ( )
private

Updates the CoordinateSystem in the ImageConcat image.

The first lattice must be an image. The first lattice is contiguous by definition. The Coordinate System for the first image must be set before calling this function. For the first image, this function just sets up worldValues and pixelValues

template<class T>
void casacore::ImageConcat< T >::setImage ( ImageInterface< T > &  image,
Bool  relax 
)

Sets a new image into the list to be concatenated.

If relax is False, throws an exception if the images are not contiguous along the concatenation axis. If relax is True, it will create a non-regular TabularCoordinate for non-contiguous images if the coordinates are monotonic. Otherwise, it just uses the coordinates of the image

template<class T>
virtual Bool casacore::ImageConcat< T >::setImageInfo ( const ImageInfo info)
virtual

Set the ImageInfo in the super class ImageInterface and in each underlying image.

If needed, its restoring beam is split along the frequency or polarisation axis and set in each underlying image.

Reimplemented from casacore::ImageInterface< T >.

template<class T>
void casacore::ImageConcat< T >::setLattice ( MaskedLattice< T > &  lattice)

Add a clone of the lattice to the list to be concatenated.

You can only concatenate a lattice with an image if you have first used setImage to set an image (this provides the CooridinateSystem information)

template<class T>
virtual Bool casacore::ImageConcat< T >::setMiscInfo ( const RecordInterface newInfo)
virtual

Replace the miscinfo in the ConcatImage, which writes the image.concat file.

It can fail if, e.g., the directory to write to is not writable.

Reimplemented from casacore::ImageInterface< T >.

template<class T>
virtual IPosition casacore::ImageConcat< T >::shape ( ) const
virtual

Return the shape of the concatenated image.

Implements casacore::LatticeBase.

template<class T>
virtual void casacore::ImageConcat< T >::tempClose ( )
virtual

Temporarily close the lattice.

It will be reopened automatically on the next access.
By default the function does not do anything at all.

Reimplemented from casacore::LatticeBase.

template<class T>
virtual void casacore::ImageConcat< T >::unlock ( )
virtual

Reimplemented from casacore::LatticeBase.
