Detailed Description

ASCII85 encoder class.

Library: xviews or winviews or mviews (mutually exclusive)

This class allows you to encode binary data to data in ASCII characters representation. For every 4 bytes of input data, 5 bytes are generated. This encoding uses an ASCII 85 base, generating characters in the range ! through u.
