class CSS::Font::Resources::Source

Abstract base class for font source references

Description

This is an abstract base class for font descriptor source references. See also instance classes:

• CSS::Font::Resources::Source::Local for local(...) references.

• CSS::Font::Resources::Source::Url for url(...) references.

Example

use CSS::Font::Descriptor;
use CSS::Font::Resources;
use CSS::Font::Resources::Source;
my CSS::Font::Descriptor @font-face;
@font-face.push: CSS::Font::Descriptor.new: :font-family("DejaVu Sans"), :src<url("fonts/DejaVuSans.ttf")>;
@font-face.push: CSS::Font::Descriptor.new: :font-family<serif>, :font-weight<bold>, :src<local(DejaVuSans-Bold)>;
my $font = "bold 12pt times roman, serif";
my CSS::Font::Resources $fonts .= new: :$font, :@font-face;
my CSS::Font::Resources::Source @sources = $fonts.sources;
with @sources.head -> $src {
    say ($src.type, $src.format, $src.IO.path).join: ', ';
    # has matched the second descriptor.
    # results may be system dependant, e.g.:
    # local, truetype, /usr/share/fonts/truetype/dejavu/DejaVuSerif-Bold.ttf
}
