Detailed Description

Provides and lists information about the header of an image.

Prerequisite

Etymology

This class lists the ancilliary or header information from a MeasurementSet in a Summary format.

Synopsis

MSs consist of pixels and descriptive information stored in what is loosely termed the header. This is information describing the coordinate system, the image units etc. This class enables you to retrieve the descriptive header information and/or list it.

Example

PagedMS<Float> inMS(fileName);
MSSummary<Float> header(inMS);
LogOrigin or("myClass", "myFunction(...)", WHERE);
LogIO os(or);
header.list(os);

A PagedMS object is constructed and then logged to the supplied LogIO object.

Caution: Note that if the PagedMS goes out of scope, this class will retrieve rubbish as it just maintains a pointer to the image;

Motivation

The viewing of the image header is a basic capability that is commonly required.
