PdfContentStream Class

Definition

Defines a low level graphics interface for drawing content on PDF pages.

C#

public class PdfContentStream : Object

Inheritance: Object → PdfContentStream

Remarks

The methods in this class match the PDF operators defined in the PDF specification.
A PdfContentStream object is created from a PdfGraphics object and lets you inject specific PDF operators in the PdfGraphics object, operators that are not available through the public API.
This class gives you full control over the generated page content but it requires good knowledge of PDF specification.
