Prima::PS::Drawable(3)User Contributed Perl DocumentatioPrima::PS::Drawable(3)

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

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

	       my $x = Prima::PS::Drawable-> create( onSpool =>	sub {
		       open 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;

       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
	   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 is not realized (	yet?)

   Specific properties
	   amount of copies that PS interpreter	should print

	   could be 0 or 1

	   physical page dimension, in points

	   non-printable page area, an array of	4 integers: left, bottom,
	   right and top margins in points.

	   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.

	   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.

	   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

	   Default value is 0

   Internal methods
	   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.

	   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.

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