FontObj

Methods

### font-name

The font name

### height

Overall font height

### encode

Encodes strings

### decode

Decodes buffers

### kern

Kern text via the font's kerning tables. Returns chunks of text separated by numeric kern widths.

say $font.kern("ABCD"); # ["AB", -18, "CD"]

### glyph-width

Return the width of a glyph. This is a `rw` method that can be used to globally adjust a font's glyph spacing for rendering and string-width calculations:

say $vera.glyph-width('V'); # 684;
$vera.glyph-width('V') -= 100;
say $vera.glyph-width('V'); # 584;

to-dict

Produces a draft PDF font dictionary. cb-finish() needs to be called to finalize it.

cb-finish

Finishing hook for the PDF tool-chain. This produces a finalized PDF font dictionary, including embedded fonts, character widths and encoding mappings.

is-embedded

Whether a font-file is embedded.

is-subset

Whether the font has been subsetting

is-core-font

Whether the font is a core font

has-encoding

Whether the font has unicode encoding. This is needed to encode or extract text.

underline-position

Position, from the baseline where an underline should be drawn. This is usually negative and should be multipled by the font-size/1000 to get the actual position.

underline-thickness

Recommended underline thickness for the font. This should be multipled by font-size/1000.

face

Font::FreeType::Face object associated with the font.

If the font was loaded from a `$dict` object and `is-embedded` is true, the `face` object has been loaded from the embedded font, otherwise its a system-loaded font, selected to match the font.

stringwidth

method stringwidth(Str $text, Numeric $point-size?, Bool :$kern) returns Numeric

Returns the width of the string passed as argument.

By default the computed size is in 1000's of a font unit. Alternatively second `point-size` argument can be used to scale the width according to the font size.

The `:kern` option can be used to adjust the stringwidth, using the font's horizontal kerning tables.

get-glyphs

use PDF::Font::Loader::Glyph;
my PDF::Font::Loader::Glyph @glyphs = $font.get-glyphs: "Hi";
say "name:{.name} code:{.code-point} cid:{.cid} gid:{.gid} dx:{.dx} dy:{.dy}"
    for @glyphs;

Maps a string to glyphs, of type PDF::Font::Loader::Glyph.
