Composer - Fallback Fonts

This example shows how to use the fallback font support of HexaPDF to replace invalid glyphs with ones from other fonts.

While the examples shows the usage of a single fallback font, it can easily be generalized to support multiple fallback fonts.

Usage:: ruby composer_fallback_fonts.rb
Resulting PDF:: composer_fallback_fonts.pdf

Code

require 'hexapdf'

HexaPDF::Composer.create('composer_fallback_fonts.pdf') do |composer|
  zapf_dingbats = composer.document.fonts.add('ZapfDingbats')
  composer.document.config['font.fallback'] = ['ZapfDingbats']
  composer.text('This text contains the scissors symbol ✂ which is not available in ' \
                'the default font Times but available in the set ZapfDingbats fallback ' \
                'font. Other symbols from ZapfDingbats like ✐ and ✈ can also be used.' \
                "\n\n❤ HexaPDF")
