Detailed Description

An abstract class that provides an interface to a basic image format.

Requirements are things like I/O and georeferencing as well as general information about the image.

To add a new image format to glimsview, all one needs to do is extend this class, override and implement its abstract routines, and fill in the mImageInf member. A recompilation of the source will be necessary.

Notes: An additional feature to glimsview would be to reimplement this as another plugin interface that dynamically loads the image formats available to the application on start that would be stored in a particular directory, i.e. ./formats/. This would allow anyone to append their own file format without the source. [Dan Mingus]
