Usage

Usage is quite simple.

The following code is used to write the generated captcha to a file named "captcha1.jpg":

local captcha = require 'captcha'
local filename = "captcha1.jpg"
-- Create the captcha object
local cap = captcha.new()
-- Set font (required)
cap:font("./Vera.ttf")
cap:write(filename, 70)
print("Captcha text " .. cap:getStr() .. "\n")
