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 PDFconts
- the new contentcompressionLevel
- 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
-
setDataRaw
public void setDataRaw(byte[] data)
Sets the data associated with the stream, as-is. This method will not remove or change any existing filter: the data has to match an existing filter or an appropriate filter has to be set.- Parameters:
data
- data, possibly encrypted and/or compressed- Since:
- 5.5.0
-
setData
public void setData(byte[] data)
Sets the data associated with the stream- Parameters:
data
- raw data, decrypted and uncompressed.
