如何在Windows Phone 7上操作图像 [英] How to manipulate image on windows phone 7

问题描述

反正有没有办法操纵Windows Phone相机拍摄的图像?
它不像棕褐色那样编辑它或将其转换成黑白，我想要的是在它上面添加框架，或者其他一些有趣的东西，例如帽子，眼镜或类似的东西.
我进行了搜索，但发现的全部是将图像转换为其他颜色.

Is there anyway to manipulate images taken by the windows phone camera?
Its not editing it like sepia or converting it to black and white, what I would like is adding frames on top of it, or maybe some other funny stuffs like hats or glasses or stuffs like that.
I searched for it, but all I found are converting the images to another colors.

推荐答案

所以，无论如何，因为似乎没有答案，所以这是我最终做到了:

So, anyway, because it seems like there is no answer, here is how i ended up doing it:

public partial class MainPage : PhoneApplicationPage
    {
        WriteableBitmap wb;
        PhotoCamera cam;

        //constructors, other stuffs...
        protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
                {
                    base.OnNavigatedTo(e);
                    cam = new PhotoCamera();
                    this.cam.CaptureCompleted += new EventHandler(cam_CaptureCompleted);
                    this.cam.CaptureImageAvailable += new EventHandler(cam_CaptureImageAvailable);
                }

    void cam_CaptureImageAvailable(object sender, ContentReadyEventArgs e)
        {
            Dispatcher.BeginInvoke(() => {
                BitmapImage bi = new BitmapImage();
                bi.SetSource(e.ImageStream);
                previewImage1.Source = bi;
                wb = new WriteableBitmap(ImageStack, null);
                previewImage.Source = wb;
            }); 
        }

因此，基本上，我将一个Image对象，要堆叠在一起的帧/精灵放到一个网格中，在照片捕获了相机之后，图像源将设置为该照片，然后使用该图像栈初始化了一个WritableBitmap ..
当然，因此，图片的分辨率仅限于应用程序的分辨率，但是，总比没有好...

So, basically, i put an Image object, the frames/sprites that i wanted to stack together into a grid, after the photo captured the camera, the image source will be set to that photo, and i initialized a WritableBitmap using that image stack..
of course, because of this, the resolution of the picture is limited to the resolution of the application, but well, better than nothing...
