NAME

PDF::Builder::Resource::Font::CoreFont - Module for using the 14 standard PDF built-in Fonts (plus 15 Windows Fonts).

SYNOPSIS

    #
    use PDF::Builder;
    #
    my $pdf = PDF::Builder->new();
    my $cft = $pdf->font('Times-Roman');
   #my $cft = $pdf->corefont('Times-Roman');
    #
    my $page = $pdf->page();
    my $text = $page->text();
    $text->font($cft, 20);
    $text->translate(200, 700);
    $text->text("Hello, World!");

METHODS

new

    $font = PDF::Builder::Resource::Font::CoreFont->new($pdf, $fontname, %options)

Returns a corefont object.

Valid %options are:

Changes the encoding of the font from its default. See perl's Encode for the supported values. Warning: only single byte encodings are permitted. Multibyte encodings such as 'utf8' are forbidden.
Changes the reference-name of the font from its default. The reference-name is normally generated automatically and can be retrieved via "$pdfname=$font-"name()>.

Supported typefaces

standard PDF types

  • helvetica, helveticaoblique, helveticabold, helvetiaboldoblique

    May have Arial substituted on some systems (e.g., Windows)

  • courier, courieroblique, courierbold, courierboldoblique

    Fixed pitch, may have Courier New substituted on some systems (e.g., Windows)

  • timesroman, timesitalic, timesbold, timesbolditalic

    May have Times New Roman substituted on some systems (e.g., Windows)

  • symbol, zapfdingbats

Primarily Windows typefaces

  • georgia, georgiaitalic, georgiabold, georgiabolditalic
  • verdana, verdanaitalic, verdanabold, verdanabolditalic
  • trebuchet, trebuchetitalic, trebuchetbold, trebuchetbolditalic
  • bankgothic, bankgothicitalic, bankgothicbold, bankgothicitalic

    Free versions of Bank Gothic are often only medium weight Roman (bankgothic).

  • webdings, wingdings

Keep in mind that only font metrics (widths) are provided with PDF::Builder; the fonts themselves are provided by the reader's machine (often packaged with the operating system, or obtained separately by the user). To use a specific font may require you to obtain one or more files from some source.

If a font (typeface and variant) is not available on a given reader's machine, a substitution may be automatically made. For example, Helvetica is usually not shipped with Windows machines, and Arial might be substituted. For most characters, the glyph widths will be the same, but this can not be guaranteed!

PDF::Builder currently uses the [typeface].pm files to map glyph names to code points (single byte encodings only) and to look up the glyph widths for character positioning. There is no guarantee that a given font file includes all the desired glyphs, nor that the widths will be absolutely the same, even in different releases of the same font.

is_standard

    $bool = $class->is_standard($name)

Returns true if $name is an exact, case-sensitive match for one of the standard font names shown above.

loadallfonts

    PDF::Builder::Resource::Font::CoreFont->loadallfonts()

"Requires in" all fonts available as corefonts.
