如何在WP7中使用C#裁剪图像 [英] How to CROPPING image with C# in WP7

问题描述

我遇到了难题，无法解决自己的问题.
我想裁剪image1，然后从相机任务中获取图片.

I Have hard problem i can''t fix it my self.
I want to cropping image1 and after get picture from camera task.

private void button1_Click(object sender, RoutedEventArgs e)
{
    CameraCaptureTask task = new CameraCaptureTask();
    task.Completed += (s, evt) =>
    {
        if (evt.Error == null && evt.TaskResult == TaskResult.OK)
        {
            bmpImage.SetSource(evt.ChosenPhoto);
            image1.Source = bmpImage;
        }
    };
    task.Show();
}

exp:image1的分辨率为1000px * 1000px

现在我想将button2添加到image1中的图像中:
从x = 100到x = 800
从y = 200到y = 700
所以我有了新的imgae1分辨率700 * 500.
我在 http://msdn.microsoft.com/en-us/library/ms752345中找到了解决方案. aspx [^ ]
此处的代码:

exp: image1 have resolution 1000px * 1000px

now I want add button2 to crop image in image1:
from x=100 to x=800
from y=200 to y=700
so I have new imgae1 resolution 700*500.
I Found Solution for this in http://msdn.microsoft.com/en-us/library/ms752345.aspx[^]
here the code:

// Create an Image element.
            Image croppedImage = new Image();
            croppedImage.Width = 200;
            croppedImage.Margin = new Thickness(5);

            // Create a CroppedBitmap based off of a xaml defined resource.
             
            CroppedBitmapcb = new CroppedBitmap(
               (BitmapSource)this.Resources["masterImage"],
               new Int32Rect(30, 20, 105, 50));       //select region rect
            croppedImage.Source = cb;                 //set image source to cropped

上面的代码是找不到命名空间"CroppedBitmap"的错误.
请帮助我的问题

The code above is error the namespace ''CroppedBitmap'' not found.
please help my problem

推荐答案

您是否已添加"PresentationCore.dll"作为参考?

如果是，那么，您是否引用了Imaging命名空间?

Have you added ''PresentationCore.dll'' as reference?

If yes then, have you refereed Imaging namespace?

using System.Windows.Media.Imaging;
