NAME

6       Text::Layout::FontConfig - Pango style font description for
7       Text::Layout
8

SYNOPSIS

10       Font descriptors are strings that identify the characteristics of the
11       desired font. For example, "Sans Italic 20".
12
13       The PDF context deals with physical fonts, e.g. built-in fonts like
14       "Times-Bold" and fonts loaded from font files like
15       "/usr/share/fonts/dejavu/DejaVuSans.ttf".
16
17       To map font descriptions to physical fonts, these fonts must be
18       registered. This defines a font family, style, and weight for the font.
19
20       Note that Text::Layout::FontConfig is a singleton. Creating objects
21       with new() will always return the same object.
22
23   METHODS
24       new( [ atts... ] )
25           For convenience only. Text::Layout::FontConfig is a singleton.
26           Creating objects with new() will always return the same object.
27
28           Attributes:
29
30           corefonts
31               If true, a predefined set of font names (the PDF corefonts) is
32               registered.
33
34       register_fonts( $font, $family, $style [ , $weight ] [ , $props ] )
35           Registers a font fmaily, style and weight for the given font.
36
37           $font can be the name of a built-in font, or the name of a TrueType
38           or OpenType font file.
39
40           $family is a font family name such as "normal", "sans", "serif", or
41           "monospace". It is possible to specify multiple family names, e.g.,
42           "times, serif".
43
44           $style is the slant style, one of "normal", "oblique", or "italic".
45
46           $weight is the font weight, like "normal", or "bold".
47
48           For convenience, style combinations like "bolditalic" are allowed.
49
50           A final hash reference can be passed to specify additional
51           properties for this font. Recognized properties are:
52
53           •   "shaping" - If set to a true value, this font will require text
54               shaping. This is required for fonts that deal with complex
55               glyph rendering and ligature handling like Devanagari.
56
57               Text shaping requires module HarfBuzz::Shaper.
58
59           •   "interline" - If set to a true value, an alternative way to
60               determine glyph height is used. This may improve results for
61               some fonts.
62
63       add_fontdirs( @dirs )
64           Adds one or more file paths to be searched for font files.
65
66       register_aliases( $family, $aliases, ... )
67           Adds aliases for existing font families.
68
69           Multiple aliases can be specified, e.g.
70
71               $layout->register_aliases( "times", "serif, default" );
72
73           or
74
75               $layout->register_aliases( "times", "serif", "default" );
76
77       register_corefonts( $noaliases )
78           This is a convenience method that registers all built-in corefonts.
79
80           Aliases for families "serif", "sans", and "monospace" are added
81           unless $noaliases is specified.
82
83           You do not need to call this method if you provide your own font
84           registrations.
85
86       find_font( $family, $style, $weight )
87           Returns a font descriptor based on the given family, style and
88           weight.
89
90           On Linux, fallback using fontconfig.
91
92       from_string( $description )
93           Returns a font descriptor using a Pango-style font description,
94           e.g.  "Sans Italic 14".
95
96           On Linux, fallback using fontconfig.
97
98       parse( $description )
99           Parses a Pango-style font description and returns a hash ref with
100           keys "family", "style", "weight", and "size".
101
102           Unspecified items are returned as empty strings or, in the case of
103           "size", zero.
104
105       from_filename( $filename )
106           Returns a font descriptor from a filename. Tries to infer Pango
107           data from the name.
