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)
