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:
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,
                    boolean compress,
                    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:
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
