Question

你能给我一个使用诺基亚Imaging SDK 1.2裁剪图像的示例代码吗？如您所知，“编辑会话”类，我用于裁剪图像已经在SDK 1.2中使用了。谢谢你的关注。

这是诺基亚api参考文档的摘录，可在此处找到：

http://developer.nokia.com/resources/library/Imaging_API_Ref/nokiagraphicsimaging-namespace/cropfilter-class.html

此示例获取CameraCaptureTask结果照片并对其应用[crop]过滤器。

async void CaptureTask_Completed(object sender, PhotoResult e)
{
    // Create a source to read the image from PhotoResult stream
    using (var source = new StreamImageSource(e.ChosenPhoto))
    {
        // Create effect collection with the source stream
        using (var filters = new FilterEffect(source))
        {
            // Initialize the filter 
            var sampleFilter = new CropFilter(new Windows.Foundation.Rect(0, 0, 500, 500));

            // Add the filter to the FilterEffect collection
            filters.Filters = new IFilter[] { sampleFilter };

            // Create a target where the filtered image will be rendered to
            var target = new WriteableBitmap((int)ImageControl.ActualWidth, (int)ImageControl.ActualHeight);

            // Create a new renderer which outputs WriteableBitmaps
            using (var renderer = new WriteableBitmapRenderer(filters, target))
            {
                // Render the image with the filter(s)
                await renderer.RenderAsync();

                // Set the output image to Image control as a source
                ImageControl.Source = target;
            }
        }
    }
}

在nokia Imaging SDK 1.2中裁剪图像？
