Ruby/GD2 - Home

Ruby/GD2 is a Ruby interface to Thomas Boutell’s gd 2 graphics library.

Using Ruby/GD2, you can write Ruby code like this:

        require 'gd2'

        include GD2
        image = Image.import('image.png')
        image.resize! 200, 300
        image.draw do |pen|
                pen.color = image.palette.resolve Color[1.0, 0.75, 0.5]
                pen.thickness = 2
                pen.move_to 25, 50
                pen.line_to 175, 50
                pen.move -150, 25
                pen.font = Font::TrueType['/usr/share/fonts/times.ttf', 20]
                pen.text 'Hello, world!'
        end
        image.export('new-image.png')
