Font Validation

Fontisan provides tools to validate font files for correctness and compliance.

Basic Validation

ruby

require 'fontisan'

# Validate a font file
result = Fontisan.validate('font.ttf')

if result.valid?
  puts "Font is valid!"
else
  puts "Validation errors:"
  result.errors.each do |error|
    puts "  - #{error}"
  end
end

Validation Options

ruby

# Strict validation (includes optional checks)
result = Fontisan.validate('font.ttf', strict: true)

# Validate specific aspects
result = Fontisan.validate('font.ttf', checks: [:tables, :glyphs, :names])

Collection Validation

For TrueType/OpenType Collections:

ruby

# Validate a TTC file
result = Fontisan.validate_collection('fonts.ttc')

# Validate a specific font within the collection
result = Fontisan.validate_collection('fonts.ttc', index: 0)
