NAME

       Prima::PS::Drawable -  PostScript interface to Prima::Drawable

SYNOPSIS

               use Prima;
               use Prima::PS::Drawable;

               my $x = Prima::PS::Drawable-> create( onSpool => sub {
                       open F, ">> ./test.ps";
                       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 PostScript level 2 document language.  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
       ::copies
           amount of copies that PS interpreter should print

       ::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.

       ::useDeviceFonts
           1 by default; optimizes greatly text operations, but takes the risk that a character
           could be drawn incorrectly or not drawn at all - this behavior depends on a particular
           PS interpreter.

       ::useDeviceFontsOnly
           If 1, the system fonts, available from Prima::Application interfaces can not be used.
           It is designed for developers and the outside-of-Prima applications that wish to use
           PS generation module without graphics. If 1, "::useDeviceFonts" is set to 1
           automatically.

           Default value is 0

   Internal methods
       emit
           Can be called for direct PostScript code injection. Example:

                   $x-> emit('0.314159 setgray');
                   $x-> bar( 10, 10, 20, 20);

       pixel2point and point2pixel
           Helpers for translation from pixel to points and vice versa.

       fill & stroke
           Wrappers for PS outline that is expected to be filled or stroked.  Apply colors, line
           and fill styles if necessary.

       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::font plus those that defined into Prima::PS::Fonts module.
