Glyph-Related Methods
glyphNames
@names = $font->glyphNames()
Return the defined glyph names of the font.
glyphNum
$glNum = $font->glyphNum()
Return the number of defined glyph names of the font.
uniByGlyph
$uni = $font->uniByGlyph($char)
Return the unicode by glyph name.
uniByEnc
$uni = $font->uniByEnc($char)
Return the Unicode by the font's encoding map.
uniByMap
$uni = $font->uniByMap($char)
Return the Unicode by the font's default map.
encByGlyph
$char = $font->encByGlyph($glyph)
Return the character by the given glyph name of the font's encoding map.
encByUni
$char = $font->encByUni($uni)
Return the character by the given Unicode of the font's encoding map.
mapByGlyph
$char = $font->mapByGlyph($glyph)
Return the character by the given glyph name of the font's default map.
mapByUni
$char = $font->mapByUni($uni)
Return the character by the given Unicode of the font's default map.
glyphByUni
$name = $font->glyphByUni($unicode)
Return the glyph's name by the font's Unicode map. CAUTION: non-standard glyph-names are mapped onto
the ms-symbol area (0xF000).
glyphByEnc
$name = $font->glyphByEnc($char)
Return the glyph's name by the font's encoding map.
glyphByMap
$name = $font->glyphByMap($char)
Return the glyph's name by the font's default map.
wxByGlyph
$width = $font->wxByGlyph($glyph)
Return the glyph's width. This is a value, that when divided by 1000 and multiplied by the font size
(height in points), gives the advance width to the next character's start. Typically, the width will
be under 1000.
wxByUni
$width = $font->wxByUni($uni)
Return the Unicode character's width. This is a value, that when divided by 1000 and multiplied by
the font size (height in points), gives the advance width to the next character's start. Typically,
the width will be under 1000.
wxByEnc
$width = $font->wxByEnc($char)
Return the character's width based on the current encoding. This is a value, that when divided by
1000 and multiplied by the font size (height in points), gives the advance width to the next
character's start. Typically, the width will be under 1000.
wxMissingByEnc
$flag = $font->wxMissingByEnc($char)
Return true if the character's width (based on the current encoding) is supplied by "missing width"
of font.
wxByMap
$width = $font->wxByMap($char)
Return the character's width based on the font's default encoding. This is a value, that when
divided by 1000 and multiplied by the font size (height in points), gives the advance width to the
next character's start. Typically, the width will be under 1000.
width
$wd = $font->width($text)
Return the width of $text as if it were at font size 1 (unscaled). CAUTION: works correctly only if
a proper Perl string is used, either in native or UTF-8 format (check utf8-flag).
width_array
@widths = $font->width_array($text)
Return (as an array) the widths of the words in $text as if they were at size 1.

Return the utf8-string from string based on the font's encoding map.
strByUtf
$string = $font->strByUtf($utf8_string)
Return the encoded string from utf8-string based on the font's encoding map.
textByStr
$pdf_string = $font->textByStr($string)
Return a properly formatted representation of $string for use in the PDF.
textByStrKern
$pdf_string = $font->textByStrKern($string)
Return a properly formatted representation of $string, with kerning, for use in the PDF.
