Provides a GUI framework for simple, non-interactive image processing operations in which one output image is generated from a single input image.
The input image is read from a file, checked and processed to produce the output image. A frame is then created, containing a tabbed pane which displays the input and output images.
This is an abstract class, and must be extended to be used. The input and output images can be accessed within derived classes as inputImage and outputImage, respectively. Derived classes must supply definitions for the method imageOK, which checks whether the input image is suitable for processing, and the method processImage, which carries out the processing.
