11
12               my $x = Prima::PS::PostScript-> create( onSpool => sub {
13                       open F, ">> ./test.ps";
14                       print F $_[1];

DESCRIPTION

23       Realizes the Prima library interface to PostScript level 2 document
24       language.  The module is designed to be compliant with Prima::Drawable
25       interface.  All properties' behavior is as same as Prima::Drawable's,
26       except those described below.
27
28   Inherited properties
29       ::resolution
30           Can be set while object is in normal stage - cannot be changed if
31           document is opened. Applies to fillPattern realization and general
32           pixel-to-point and vice versa calculations
33
34       ::alpha
35           - ::alpha is not implemented
36
37   Specific properties
38       ::copies
39           amount of copies that PS interpreter should print
40
41       ::grayscale
42           could be 0 or 1
43
44       ::pageSize
45           physical page dimension, in points
46
47       ::pageMargins
48           non-printable page area, an array of 4 integers: left, bottom,
49           right and top margins in points.
50
51       ::reversed
52           if 1, a 90 degrees rotated document layout is assumed
53
54       ::rotate and ::scale
55           along with Prima::Drawable::translate provide PS-specific
56           transformation matrix manipulations. ::rotate is number, measured
57           in degrees, counter-clockwise. ::scale is array of two numbers,
58           respectively x- and y-scale. 1 is 100%, 2 is 200% etc.
59
60   Internal methods
61       emit
62           Can be called for direct PostScript code injection. Example:
63
64                   $x-> emit('0.314159 setgray');
65                   $x-> bar( 10, 10, 20, 20);
66
67       pixel2point and point2pixel
68           Helpers for translation from pixel to points and vice versa.
69
70       fill & stroke
71           Wrappers for PS outline that is expected to be filled or stroked.
72           Apply colors, line and fill styles if necessary.
73
74       spool
75           Prima::PS::PostScript is not responsible for output of generated
76           document, it just calls ::spool when document is closed through
77           ::end_doc. By default just skips data.  Prima::PS::Printer handles
78           spooling logic.
79
80       fonts
81           Returns Prima::Application::fonts, however with "iso10646-1"
82           encoding only.  That effectively allows only unicode output.
