Detailed Description

Synopsis

ImageProxy is a proxy to an image having data type Float, Double, Complex, or DComplex. Its primary purpose is to be bind the images module to Python through pyrap.images. However, it can also be used directly in C++.

An ImageProxy object can be constructed for an image stored on disk in Casacore, FITS, HDF5, or Miriad format. It can also be constructed given a shape or an N-dim array with values. Furthermore it can be constructed from a LEL expression (see class ImageExpr) or a vector of images to be concatenated (see class ImageConcat).

Many functions exist to operate on an ImageProxy object. For example:

Functions regrid and statistics can only be used for Float images. They throw an exception for images with other data types. Note that using a LEL expression it is possible to (virtually) convert an image with another type to a Float image.
