将.html文件转换为图片

Question

我正在寻找一个能够忠实地将.html文件转换为图像格式（最好是png或jpeg）的工具。我已经谷歌了几个小时并下载了十几个免费试用版，但似乎没有一个能胜任这项工作。Adobe Acrobat Pro 差点就可以胜任，但它会决定将表格单元格缩小以适应页面，而不是缩小整个表格。如有建议，请告知。祝好！

假设您尝试做的页面太多，无法简单地将它们全部一起截屏打印出来？ - Austin

这个东西 http://awesomium.com/ 可以用吗？ - Mike Christensen

我使用Firefox的Screengrab扩展。Chrome有一些类似的扩展程序。 - j08691

也许这个帖子可以帮助。 - user377628

有许多适用于Firefox的插件可以完成这个任务。您的具体使用情况是什么？ - steveax

谢谢大家。把问题写出来让我找到了解决办法。我只需要在表格单元格中添加nowrap，Acrobat就可以正常工作了。 - Kevin

我正在使用wkhtmltoimage。

它是一个快速的命令行工具，使用webkit库渲染任何网站。有两个版本，一个用于生成pdf，另一个用于生成图像。wkhtmltoimage适用于Windows、Linux和Mac。

你是如何生成这些图片的？在我的使用中，它们都没有出现，CSS也是。 - nmrlqa4

如果您需要一个命令行程序，请尝试IECapt。它使用Internet Explorer渲染引擎。还有一个名为CutyCapt的跨平台实用程序，我没有尝试过哪个更好。关于IECapt的文件参数，需要指定完整路径才能正常工作。似乎不识别相对路径。路径中允许使用引号，例如：--file:"C:\....."。

还有PhantomJS（参见http://phantomjs.org）。 我在一个用PHP编写的搜索引擎中使用它来生成网站缩略图。 像wkhtmltoimage一样，它是基于WebKit的命令行程序，可以生成图像和PDF。但由于它是一个完整的浏览器，它使用JavaScript进行处理。

编辑：请参阅https://github.com/ariya/phantomjs/wiki/Screen-Capture以获取图像渲染的具体示例。
