NAME
Prima::PS::PDF - PDF interface to Prima::Drawable
SYNOPSIS
Recommended usage:
use Prima::PS::Printer;
my $x = Prima::PS::PDF::File-> new( file => 'out.pdf');
or
my $x = Prima::PS::PDF::FileHandle-> new( handle => \&STDOUT);
Low-level:
use Prima::PS::PDF;
my $x = Prima::PS::PDF-> create( onSpool => sub {
open F, ">> ./test.pdf";
binmode F;
print F $_[1];
close F;
});
Printing:
die "error:$@" unless $x-> begin_doc;
$x-> font-> size( 30);
$x-> text_out( "hello!", 100, 100);
$x-> end_doc;
DESCRIPTION
Implements the Prima library interface to PDF v1.4. The module is designed to be compliant with the Prima::Drawable interface. All properties' behavior is as same as Prima::Drawable's except those described below.
Inherited properties
- ::resolution
-
Can be set while the object is in the normal stage - cannot be changed if the document is opened. Applies to implementation of the fillPattern property and general pixel-to-point and vice versa calculations
Specific properties
- grayscale
-
could be 0 or 1
- pageSize
-
The physical page dimension, in points
- pageMargins
-
Non-printable page area, an array of 4 integers: left, bottom, right, and top margins in points.
- reversed
-
if 1, a 90 degrees rotated document layout is assumed
Internal methods
- pixel2point and point2pixel
-
Helpers for translation from pixel to points and vice versa.
- spool
-
Prima::PS::PDF is not responsible for the output of the generated document, it only calls the
::spool
method when the document is closed through an::end_doc
call. By default discards the data. ThePrima::PS::Printer
class handles the spooling logic. - fonts
-
Calls Prima::Application::fonts and returns its output filtered so that only the fonts that support the
iso10646-1
encoding are present. This effectively allows only unicode output.
