InMemFormat Class Reference

#include <inmemformat.h>

Inheritance diagram for InMemFormat:

Detailed Description

This is a special image format in that it does not implement a file based format.

Instead it holds a file based ImageFormat and masks its I/O routines with its own. At all times, the selected bands of an image will be held in memory instead of the usual file buffering that is done. This allows for faster access and display. The Image class uses this a little different then normal ImageFormat's.
