Examples of org.apache.pdfbox.filter.Filter.decode()

org.apache.pdfbox.filter.Filter.decode()
Decodes data, producing the original non-encoded data. @param encoded the encoded byte stream @param decoded the stream where decoded data will be written @param parameters the parameters used for decoding @param index the index to the filter being decoded @return repaired parameters dictionary, or the original parameters dictionary @throws IOException if the stream cannot be decoded
