如何设置Camera Capture Task WP7属性 [英] how to set Camera Capture Task WP7 properties

问题描述

您好，我尝试构建Windows Phone 7应用程序，但在使用相机捕获图像方面没有什么问题.

Hello, i Try build application windows phone 7, but i have little problem in capture image with the camera.

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();
       }

上面的代码可以工作100％，但是我需要在捕获时固定尺寸为320 * 240像素的图像.
任何机构都知道要设置的属性吗?

this code above work 100% but I need to fix size 320*240 pixel image while capture.
any body know the properties to set it?

推荐答案

您无法使用相机任务控制任何内容..
您应该在应用程序内的画布中打开相机

这是完整的解决方案:

you can''t control anything with the camera task..
you should open the camera in a canvas inside your app
