WPF WebBrowser - 如何缩放内容?

问题描述

尝试在 WPF(C#/XAML、.NET 4.0)WebBrowser 应用程序中测试基本浏览器概念.到目前为止，唯一的问题是以编程方式缩放.有没有人有这方面的经验?

Trying to test basic browser concepts in a WPF (C#/XAML, .NET 4.0) WebBrowser application. So far, the only problem is programatically zooming. Has anyone had any experience with this?

MSDN 没有列出任何内容:http://msdn.microsoft.com/en-us/library/system.windows.controls.webbrowser.aspx此外，我尝试了各种方法，例如 RenderTransform 选项都无济于事.这要么不可能，要么没有记录.我希望是后者.请注意，WinForm 解决方案是不可接受的.

MSDN lists nothing: http://msdn.microsoft.com/en-us/library/system.windows.controls.webbrowser.aspxAdditionally, I have tried various things such as RenderTransform options to no avail. Either this is not possible or not documented. I'm hoping for the latter. Note that a WinForm solution isn't acceptable.

在此先感谢您的帮助，贝姆斯

推荐答案

也许你可以像这样执行 javascript.

Maybe you can execute a javascript like this.

document.body.style.zoom = 1.5;

在 WPF 中，我们可以操作文档.我为你创建了一个扩展方法，所以你可以设置缩放:

In WPF we can manipulate the document. I Created a Extension Method for you, so you can set the Zoom:

// www.tonysistemas.com.br
public static partial class MyExtensions
{
    public static void SetZoom(this System.Windows.Controls.WebBrowser WebBrowser1, double Zoom)
    {
        // For this code to work: add the Microsoft.mshtml .NET reference
        mshtml.IHTMLDocument2 doc = WebBrowser1.Document as mshtml.IHTMLDocument2;
        doc.parentWindow.execScript("document.body.style.zoom=" + Zoom.ToString().Replace(",", ".") + ";");
    }
}

用法:

WebBrowser1.SetZoom(0.5);
