Provides a GUI framework for visualising a set of images derived from a single source image.
The input image is read from a file, checked and then processed to generate a set of output images, which are stored in a hashtable. A frame is then created containing a view of the first image that was generated, together with a combobox that can be used to switch the view to other images.
This is an abstract class, and must be extended to be used. Derived
classes should supply definitions for the methods
imageOK, which checks whether the input image is
suitable for processing, and generateImages,
which produces the images that are to be visualised. The latter must
add each image to the hashtable as an ImageIcon, using the method
addImage
. It must also return a Vector containing all the keys
that are required to access images in the hashtable.
