将网页另存为图像 [英] Saving a web page as image

问题描述

作为一个爱好项目，我正在探索使用c / c ++ / javascript / java将网页（HTML）保存为图片的方法大多是以编程方式。到目前为止，我已经遇到了以下方式：

As a hobby project I am exploring the ways to save a web page (HTML) as image, mostly programatically using c/c++/javascript/java. Till now I have come across the following ways:

1. 获取 IHTMLElement 使用它来查询 IHTMLElementRender ，然后使用它的 DrawToDC 方法（ Ref： / strong> http://www.codeproject.com/KB/IP/htmlimagecapture.aspx ）。但是问题是，它并不适用于所有的页面（大部分是嵌入了iframe的页面）。

1. Get the IHTMLElement of page body and use it to query for IHTMLElementRender and then use its DrawToDC method (Ref: http://www.codeproject.com/KB/IP/htmlimagecapture.aspx ). But the problem is that it did not work for all the pages (mostly pages having embedded iframes).

我可以想到的另一种方法是使用一些web浏览器组件，当页面完全加载时，使用 BitBlt （ Ref： http://msdn.microsoft.com/en-us/library/dd183370%28VS.85%29.aspx ）。但是问题是我要求的页面可能比我的屏幕尺寸长，并且不适合Web浏览器组件。

Another way which i can think of is to use some web browser component and when the pages is fully loaded then capture it using BitBlt (Ref: http://msdn.microsoft.com/en-us/library/dd183370%28VS.85%29.aspx ). But the problem is that the page I have requested may be longer than my screen size and it will not fit into the web browser component.

任何解决上述问题的方向/建议或替代方法都非常感谢。

Any direction/suggestion to resolve above issues or an alternative approach is greatly appreciated.

以上情况仍然可以。但不能保证总是工作。请查看以下链接：

Above things are still ok. BUT not guaranteed to work always. Check the below link: How do I render the scrollable regions of a canvas with IViewObject::Draw?
