PowerPoint の資料にアプリのアイコンを貼りたいので、.exe にリソースとして埋め込まれたアイコンを取り出したい。

「.exe resource extract cygwin」でググると、以下のページを見つけた。

• StackExchange / superuser / 2019-04-03: Extract icons from Windows executable

曰く、icoutils に収録されてる wrestool がいいですよと。
意外なことに 7z は .exe をアーカイブ扱いしてリソースを extract 出来ますよと。マジか。

これはどちらも Cygwin にも収録されている。

• Cygwin / Packages
  • icoutils
  • p7zip

コマンド プロンプト (cmd.exe) について試した結果を以下に示す。
.ico → .png の変換は ImageMagick の convert を使っている。
