ペンギンの画像をBASE64エンコードすると,上記のような文字列になる。

このような文字列に変換すれば,HTML内部に埋め込む事もできる。

imgタグの中に <img src="data:〜〜"> と書く。

そうすれば,ファイル数が減り,外部ファイルを用意しなくてすむ。


また,imgタグ内のURLを,JavaScriptで動的に書き換えることも可能だ。

その場合,「JavaScriptから画像を生成できる」ということになる。

画像ファイルを別個に準備する必要が無い。



このような「BASE64エンコード形式」の変換を,手軽に実行するバッチがある。

対象ファイルを下記のバッチにドラッグ・ドロップするだけ。


同一フォルダ上のテキストに,エンコード結果が出力される。


base64.bat

cscript.exe //nologo //E:JScript "%~f0" encode "%1" > "%~f0\..\encoded.txt"

BASE64に関する解説:

バッチで,BASE64のエンコード+デコードする方法 (WSH/JScriptで,バイナリのファイルをテキスト符号化)
http://language-and-engineering.hatenablog.jp/entry/20101022/p1

  • BASE64を使えば,バイナリのファイルをテキストデータ(英数字)に変換できる


小さい画像をbase64をかけてhtml内に埋め込み -
http://d.hatena.ne.jp/moogme/20090814/p3

  • Webサイトの表示速度が遅い原因の1つが、沢山画像を使っていること。 画像自体をキャッシュしても、更新がないか確認するためのアクセスが足を引っ張っていることも
  • サーバへのアクセスを無くすために、小さい画像はhtml内に埋め込むこと


画像をBase64に変換するツール (data URI scheme) - シングスブログ
http://blog.thingslabo.com/archives/0...

  • Google のウェブ検索結果でウェブページのスクリーンショットに使われている data URI scheme。 data:[<mediatype>][;base64],<data>
  • ウェブページに埋め込むことで HTTP リクエストを減らせるメリットがある


ブラウザでBase64エンコードされた画像をデコードして閲覧する - blue_ham_cake1024のブログ
http://blue-ham-cake1024.hatenablog.c...

  • ブラウザのアドレスバーにdata:image/jpeg;base64,{{Base64文字列}}みたいな感じで入力して移動すると表示できる
  • MIMEタイプのところを変えればPNGやGIFといった他の形式の画像や、テキストファイルなんかも表示できる


エンコード後のファイルサイズが133%になる事について:

BASE64のエンコード時のサイズについて | その他(メールサービス・ソフト)のQ&A【OKWave】
http://okwave.jp/qa/q202395.html

  • BASE64のエンコードは3Byte(24bit)→4Byteに変換する。なのでBASE64でエンコードしたファイルは常に約33%ファイルサイズが増加する


メールサイズの上限が10MBなのに10MBの添付ファイルが送れない理由 - mikage014の日記
http://d.hatena.ne.jp/mikage014/20090...

  • メールデータは一旦全てテキストデータに置き換えられて送信されます。 添付ファイル(バイナリデータ)をテキストに置き換えるときにサイズが大きくなってしまう


添付ファイルって、大きくならない? - PC説教講座

  • どんなシステムでも扱うことのできる、「安全な」英数字や記号、合計64文字の組み合わせに情報の形を変換してしまう
  • 64文字の組み合わせは、6ビット分の情報に相当。6ビット=2の6乗=64
