RenderTargetBitmap works fine on Windows 8.1, but not on Windows Phone 8.1
问题 I'm making a universal app. In my app I need to use RenderTargetBitmap to convert an Image and a TextBlock over the image into a JPEG photo. On the Windows 8.1 project, everything works as expected, but not on the Windows Phone 8.1 one. Could you help me with that? Thank you. My code is as follows: async Task SaveVisualElementToFile(FrameworkElement element, StorageFile file, int imageWidth, int imageHeight) { var renderTargetBitmap = new RenderTargetBitmap(); await renderTargetBitmap
