Method Details

createStream

public static PDObjectStream createStream(PDDocument document)

This will create a new PDObjectStream object.

Parameters:

document - The document that the stream will be part of.

Returns:

A new stream object.

getType

public String getType()

Get the type of this object, should always return "ObjStm".

Returns:

The type of this object.

getNumberOfObjects

public int getNumberOfObjects()

Get the number of compressed object.

Returns:

The byte offset (in the decoded stream) of the first compressed object.

Parameters:

n - The byte offset to the first object.

getExtends

public PDObjectStream getExtends()
