NAME
       CAM::PDF::GS - PDF graphic state

LICENSE
       See CAM::PDF.

SYNOPSIS
	   use CAM::PDF;
	   my $pdf = CAM::PDF->new($filename);
	   my $contentTree = $pdf->getPageContentTree(4);
	   my $gs = $contentTree->computeGS();

DESCRIPTION
       This class is used to represent the graphic state at a point in the rendering flow of a PDF page.  Much of the functionality is actually
       based in the parent class, CAM::PDF::GS::NoText.

       Subclasses that want to do something useful with text should override the renderText() method.

CONVERSION FUNCTIONS
       $self->getCoords($node)
	   Computes device coordinates for the specified node.	This implementation handles text-printing nodes, and hands all other types to the
	   superclass.

       $self->textToUser($x, $y)
	   Convert text coordinates ("Tm") to user coordinates.  Returns the converted X and Y.

       $self->textToDevice($x, $y)
	   Convert text coordinates ("Tm") to device coordinates.  Returns the converted X and Y.

       $self->textLineToUser($x, $y)
	   Convert text coordinates ("Tlm") to user coordinates.  Returns the converted X and Y.

       $self->textLineToDevice($x, $y)
	   Convert text coordinates ("Tlm") to device coordinates.  Returns the converted X and Y.

       $self->renderText($string, $width)
	   A general method for rendering strings, from "Tj" or "TJ".  This is a no-op, but subclasses may override.

       $self->Tadvance($width)
	   Move the text cursor.

DATA FUNCTIONS
       $self->BT()
       $self->Tf($fontname, $fontsize)
       $self->Tstar()
       $self->Tz($scale)
       $self->Td($x, $y)
       $self->TD($x, $y)
       $self->Tj($string)
       $self->TJ($arrayref)
       $self->quote($string)
       $self->doublequote($tw, $tc, $string)
       $self->Tm($m1, $m2, $m3, $m4, $m5, $m6)
