Constructor Summary

Constructors

Constructor	Description
PDFStream(byte[] bytes, int offset, int len, Map aMap)	Creates a new stream by copying the byte array and map
PDFStream(byte[] bytes, Map aMap)	Creates a new stream from the byte array and map.

Method Summary

Modifier and Type	Method	Description
void	addFilter(String aName)
Object	clone()	Standard clone implementation.
byte[]	decodeStream()	Returns the result of running the data through all the filters.
byte[]	decodeStream(int nfilters)	Returns the result of running the data through the first n filters.
static byte[]	getBytesDecoded(byte[] bytes, int offset, int length, String aFilter, Map params)	Returns the result of runnning the bytes through a particular filter (/FlateDecode, /LZW, /ASCII85Decode, etc.).
Map	getDictionary()	Returns the stream dictionary.
byte[]	getRawData()	Returns the stream data.
int	indexOfFilter(String fName)	Returns the index of a particular filter in the filter chain, or -1 if not found.
int	numFilters()	Returns the total number of filters with which this stream is currently encoded.
boolean	usesFilter(String fName)	Tests whether a specifc filter will be needed to decode the stream.
