第十回Wikiばな用名札作成スクリプト

これはなに?

背景画像ファイルback.png(582)と来場者名簿(サンプル)org_test.csv(1082)を読み込んで、twitterからアイコン画像を取ってきて、こんな感じのファイルhttp://twitpic.com/1tk28zを生成するスクリプト。

準備

  1. 背景画像とstaff画像は./src ディレクトリに置いとく。
  2. 出力ファイルを保存する./nafudaディレクトリを作成しとく。
  3. ソースファイルの設定
    1. Nafuda.newにcsv fileのパス, Noの列, お名前の列,twitterIDの列を指定する
    2. Twitter::HTTPAuth.newにtwitterのIDとパスワードを指定する

注意
