### PRStream

    public PRStream(PdfReader reader,
                    byte[] conts,
                    int compressionLevel)

  Creates a new PDF stream object that will replace a stream in a existing PDF file.

    `reader` - the reader that holds the existing PDF
    `conts` - the new content
    `compressionLevel` - the compression level for the content
  Since:
    2.1.3 (replacing the existing constructor without param compressionLevel)

Method Detail

### setData

    public void setData(byte[] data,
                        boolean compress)

  Sets the data associated with the stream, either compressed or uncompressed. Note that the data will never be compressed if Document.compress is set to false.

  Parameters:
    `data` - raw data, decrypted and uncompressed.
    `compress` - true if you want the stream to be compressed.
  Since:
    iText 2.1.1

### setData

    public void setData(byte[] data,

    iText 2.1.3

### setData

    public void setData(byte[] data)

  Sets the data associated with the stream

  Parameters:
    `data` - raw data, decrypted and uncompressed.

### setLength

    public void setLength(int length)

### getOffset

    public int getOffset()

### getLength

    public int getLength()

### getReader

    public PdfReader getReader()

### getBytes

    public byte[] getBytes()

  Description copied from class: `PdfObject`
  Gets the presentation of this object in a byte array

  Overrides:
    `getBytes` in class `PdfObject`
  Returns:
    a byte array

### setObjNum

    public void setObjNum(int objNum,
                          int objGen)

### getObjNum

    int getObjNum()

### getObjGen

    int getObjGen()

### toPdf

    public void toPdf(PdfWriter writer,
                      OutputStream os)
               throws IOException

  Description copied from class: `PdfDictionary`
  Writes the PDF representation of this `PdfDictionary` as an array of `byte` to the given `OutputStream`.

  Overrides:
    `toPdf` in class `PdfStream`
  Parameters:
    `writer` - for backwards compatibility
    `os` - the `OutputStream` to write the bytes to.
  Throws:
    `IOException`
