This abstract base class provides an interface for every class that is able to hold embedded data. Something that can hold embedded data is essentially though of as an array of samples.<p>
Definitions: Embedded Bit...a bit to be embedded (one bit in the original or extracted embfile) Sample...the smallest data unit in a file (e.g. a RGB triple, a DCT coefficient) <hr><h2>Member Function Documentation</h2>
