## Class ASCII85InputStream

- java.lang.Object
- - java.io.InputStream
  - - org.apache.xmlgraphics.util.io.ASCII85InputStream

- All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable, ASCII85Constants

      public class ASCII85InputStream
      extends java.io.InputStream
      implements ASCII85Constants

  This class applies a ASCII85 decoding to the stream.

  The class is derived from InputStream instead of FilteredInputStream because we can use the read(byte[], int, int) method from InputStream which simply delegates to read(). This makes the implementation easier.

  The filter is described in chapter 3.13.3 of the PostScript Language Reference (third edition).
