.html ファイルをイメージ形式 (png または jpeg が望ましい) に忠実に変換するユーティリティを探しています。私は何時間もグーグルで検索し、1ダースほどの無料試用版をダウンロードしましたが、何もうまくいかないようです. Adobe Acrobat Pro はほとんど機能しましたが、表全体を縮小するのではなく、ページに収まるように表のセルを縮小することにしました。
アドバイスをいただければ幸いです。
よろしく。

There's also PhantomJS (cf. http://phantomjs.org). I use it in a search engine written in PHP to generate the Web site thumbnails. Like wkhtmltoimage, it is a command line program based on WebKit, and can generate images and PDFs. But as it's a full browser, it uses JavaScript to do the processing.
EDIT: see https://github.com/ariya/phantomjs/wiki/Screen-Capture for a concrete sample of image rendering.
