This is the main class for working with file formats. It contains an API for loading, detecting and
saving images, getting image information, and provides access to format's settings class. The image
is read from and written to a .NET stream. In order for ImageGear to work with the stream, it must
be seekable. Consult ImageGear sample code for the examples of how to create a .NET stream from
different image sources (i.e., file, memory, URL).
