## org.apache.batik.util
Class Base64DecodeStream

    java.lang.Object
      java.io.InputStream
          org.apache.batik.util.Base64DecodeStream

public class Base64DecodeStream
extends java.io.InputStream

This class implements a Base64 Character decoder as specified in RFC1113. Unlike some other encoding schemes there is nothing in this encoding that tells the decoder where a buffer starts or stops, so to use it you will need to isolate your encoded data into a single chunk and then feed them this decoder. The simplest way to do that is to read all of the encoded data into a string and then use:

          byte    data[];
          InputStream is = new ByteArrayInputStream(data);
          is = new Base64DecodeStream(is);

On errors, this class throws a IOException with the following detail strings:

        "Base64DecodeStream: Bad Padding byte (2)."
        "Base64DecodeStream: Bad Padding byte (1)."
