Detailed Description

Reader/Writer for analyze format images.

Author:

Tim Cootes - Manchester This file contains classes for reading and writing analyze format images Three key components are vil3d_analyze_header: Structure to contain header information vil3d_analyze_image: Resource object which interfaces to the file, allowing reading and writing via the get_copy_image() and put_image() functions vil3d_analyze_format: Object to create an appropriate vil3d_analyze_image

The main work of loading and saving happens in vil3d_analyze_image
