Examples of PdfStream

com.itextpdf.text.pdf.PdfStream
PdfStream is the Pdf stream object.
A stream, like a string, is a sequence of characters. However, an application can read a small portion of a stream at a time, while a string must be read in its entirety. For this reason, objects with potentially large amounts of data, such as images and page descriptions, are represented as streams.
A stream consists of a dictionary that describes a sequence of characters, followed by the keyword stream, followed by zero or more lines of characters, followed by the keyword endstream.
All streams must be PdfIndirectObjects. The stream dictionary must be a direct object. The keyword stream that follows the stream dictionary should be followed by a carriage return and linefeed or just a linefeed.
Remark: In this version only the FLATEDECODE-filter is supported.
This object is described in the 'Portable Document Format Reference Manual version 1.7' section 3.2.7 (page 60-63).

org.apache.fop.pdf.PDFStream
class representing a PDF stream. A derivative of the PDF Object, a PDF Stream has not only a dictionary but a stream of PDF commands. The stream of commands is where the real work is done, the dictionary just provides information like the stream length.
