  24         /// とかした上で、\r

  28         /// とかして、\r

  30         /// ctBMP.t2D描画( ～～～ );\r
  31         /// で表示してください。\r
  32         /// \r
  33         /// 注意点\r
  34         /// 任意のフォントでのレンダリングは結構負荷が大きいので、なるべｋなら描画フレーム毎にフォントを再レンダリングするようなことはせず、\r
  35         /// 一旦レンダリングしたものを描画に使い回すようにしてください。\r
  36         /// また、長い文字列を与えると、返されるBitmapも横長になります。この横長画像をそのままテクスチャとして使うと、\r
  37         /// 古いPCで問題を発生させやすいです。これを回避するには、一旦Bitmapとして取得したのち、256pixや512pixで分割して\r
  38         /// テクスチャに定義するようにしてください。\r
