FreeType

FreeType module for TrueType font rendering

This module provides TrueType font parsing and rendering capabilities for the CrImage library. It implements the CrImage::Font::Face interface to enable text drawing on images.

Usage

require "crimage"
require "freetype"

# Load a TrueType font
font = FreeType::TrueType.load("path/to/font.ttf")
face = FreeType::TrueType.new_face(font, 24.0) # 24pt font

# Create an image
image = CrImage::RGBA.new(CrImage.rect(0, 0, 400, 100))

# Draw text
text_color = CrImage::Uniform.new(CrImage::Color::RGBA.new(0, 0, 0, 255))
dot = CrImage::Math::Fixed::Point26_6.new(
  CrImage::Math::Fixed::Int26_6[10 * 64],
  CrImage::Math::Fixed::Int26_6[50 * 64]
)
drawer = CrImage::Font::Drawer.new(image, text_color, face, dot)
drawer.draw("Hello, World!")

# Save the image
CrImage::PNG.write("output.png", image)
