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)
