CAM::PDF::GS(3pm) User Contributed Perl Documentation CAM::PDF::GS(3pm)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)

Text::PDF::TTFont(3pm) User Contributed Perl Documentation Text::PDF::TTFont(3pm)NAME
Text::PDF::TTFont - Inherits from Text::PDF::Dict and represents a TrueType font within a PDF file.
DESCRIPTION
A font consists of two primary parts in a PDF file: the header and the font descriptor. Whilst two fonts may share font descriptors, they
will have their own header dictionaries including encoding and widhth information.
INSTANCE VARIABLES
There are no instance variables beyond the variables which directly correspond to entries in the appropriate PDF dictionaries.
METHODS
Text::PDF::TTFont->new($parent, $fontfname, $pdfname, %opts)
Creates a new font resource for the given fontfile. This includes the font descriptor and the font stream. The $pdfname is the name by
which this font resource will be known throught a particular PDF file.
All font resources are full PDF objects.
$t->width($text)
Measures the width of the given text according to the widths in the font
$t->trim($text, $len)
Trims the given text to the given length (in per mille em) returning the trimmed text
$t->out_text($text)
Indicates to the font that the text is to be output and returns the text to be output
$f->copy
Copies the font object excluding the name, widths and encoding, etc.
TITLE
Text::PDF::TTIOString - internal IO type handle for string output for font embedding. This code is ripped out of IO::Scalar, to save the
direct dependence for so little. See IO::Scalar for details

Newbie question. I want to create a shell script that will only move/copy a file if it's determined that the eof string exists. This is to control files being uploaded via FTP. I don't want to move incomplete files, so my only thought is to check for eof, or compare file size every 15-30 seconds on... (12 Replies)
