NAME

Prima::PS::PDF - PDF interface to Prima::Drawable

SYNOPSIS

        use Prima;
        use Prima::PS::PDF;

        my $x = Prima::PS::PDF-> create( onSpool => sub {
                open F, ">> ./test.pdf";
                binmode F;
                print F $_[1];
                close F;
        });
        die "error:$@" unless $x-> begin_doc;
        $x-> font-> size( 30);
        $x-> text_out( "hello!", 100, 100);
        $x-> end_doc;

DESCRIPTION

Realizes the Prima library interface to PDF v1.4. The module is designed to be compliant with Prima::Drawable interface. All properties' behavior is as same as Prima::Drawable's, except those described below.

Inherited properties

::resolution

Can be set while object is in normal stage - cannot be changed if document is opened. Applies to fillPattern realization and general pixel-to-point and vice versa calculations

::region

- ::region is not realized ( yet?)

Specific properties

::grayscale

could be 0 or 1

::pageSize

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

::rotate and ::scale

along with Prima::Drawable::translate provide PS-specific transformation matrix manipulations. ::rotate is number, measured in degrees, counter-clockwise. ::scale is array of two numbers, respectively x- and y-scale. 1 is 100%, 2 is 200% etc.

Internal methods

pixel2point and point2pixel

Helpers for translation from pixel to points and vice versa.

spool

Prima::PS::Drawable is not responsible for output of generated document, it just calls ::spool when document is closed through ::end_doc. By default just skips data. Prima::PS::Printer handles spooling logic.

fonts

Returns Prima::Application::fonts, however with iso10646-1 encoding only. That effectively allows only unicode output.
