SYNOPSIS

    use CAM::PDF;

    my $contentTree = $pdf->getPageContentTree(4);
    my $gs = $contentTree->computeGS(1);

DESCRIPTION

This class is used to represent the graphic state at a point in the rendering flow of a PDF page. This does not include the graphics state for text blocks. That functionality is in the subclass, CAM::PDF::GS.
