ExtendedGraphicState Class Documentation

class ExtendedGraphicState

Namespace:com::datalogics::PDFL

Detailed Description

The extended graphic state, to supplement original graphic state. The Graphics State is an internal data structure in a PDF file that holds the parameters that describe graphics within that file. These parameters define how individual graphics are presented on the page, including layers and transparencies.

The Extended Graphic State was introduced to expand the original Graphics State data structure, providing space to define and store more data objects within a PDF.
