SYNOPSIS

use CAM::PDF;
my $pdf = CAM::PDF->new($filename);
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.

FUNCTIONS

$pkg->new($hashref)

Create a new instance, setting all state values to their defaults. Stores a reference to $hashref and sets the property "$hashref-"{fm}> to "undef".

$self->clone()

Duplicate the instance.

CONVERSION FUNCTIONS

$self->applyMatrix($m1, $m2)

Apply $m1 to $m2, save in $m2.

$self->dot($matrix, $x, $y)

Compute the dot product of a position against the coordinate matrix.

$self->userToDevice($x, $y)

Convert user coordinates to device coordinates.

$self->getCoords($node)

Computes device coordinates for the specified node. This implementation handles line-drawing nodes.

$self->nodeType($node)

Returns one of "block", "path", "paint", "text" or (the fallback case) "op" for the type of the specified node.

$self->d($arrayref, $scalar)

$self->m($x, $y)

Move path.
