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.

Parameters:
reader - the reader that holds the existing PDF
conts - the new content
compressionLevel - the compression level for the content
Since:

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

                    int compressionLevel)
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.
compressionLevel - a value between -1 and 9 (ignored if compress == false)
Since:

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)

toPdf

public void toPdf(PdfWriter writer,
                  java.io.OutputStream os)
           throws java.io.IOException
Description copied from class: PdfDictionary
Writes the PDF representation of this PdfDictionary as an array of byte to the given OutputStream.

Overrides:
