问题 I need serialize custom class with bitmapImage(tagged by xmlIgnore right now). I'm using xmlSerialization, but I think thats bad.Do you have some ideas how can I serialize my class??Probably you can provide some simple example?? class X { private BitmapImage someImage; public BitmaImage{get;set} } Actually later I will be use WCF Service. Thanks) 回答1: You can expose the image as a byte array, e.g.: public byte[] ImageAsBytes { get { return BytesFromImage(someImage); } set { someImage =

问题 I want that when I double click on a row in ListView , it should display the Image corresponding to that row. This row also contains the path of the Image . I tried the following but it displays the same Image for all rows because I have given the path for a specific Image : private void ListViewEmployeeDetails_MouseDoubleClick(object sender, MouseButtonEventArgs e) { ImageSource imageSource = new BitmapImage(new Uri(@"C:\northwindimages\king.bmp")); image1.Source = imageSource; } Please

问题 In my application I have to send a List<MenuItem> to my shell extension in WCF. These MenuItems are composed of an icon and a label. The type of the icon is System.Drawing.Icon but I have to work from System.Windows.Media.Imaging.BitmapImage .

问题 I have been developing a book viewing website that takes rather large images (upwards of 77+ megapixels) and scales them down before serving the image. It basically does the following algorithm: If the requested book has already been cached, serve the cached images. If the book hasn't been cached, add the book to our book-caching thread pool. The book-caching thread pool adds each book's page to our page-caching thread pool. The page-caching thread pool caches the image (located on a server

问题 I have 3D WPF visual that I want to pass into an Excel cell (via clipboard buffer). With "normal" BMP images it works but I do not know how to convert a RenderTargetBitmap . My code looks like this: System.Windows.Media.Imaging.RenderTargetBitmap renderTarget = myParent.GetViewPortAsImage(DiagramSizeX, DiagramSizeY); System.Windows.Controls.Image myImage = new System.Windows.Controls.Image(); myImage.Source = renderTarget; System.Drawing.Bitmap pg = new System.Drawing.Bitmap(DiagramSizeX,

问题 So after I pull an image out of DLL and put it into an image control it is a BitmapImage. To package it back into the dll it has to be converted back to an image. How can I convert it back to image and how can i repackage it back into the dll? This is all in wpf written in c#. private void compileDLL_Click(object sender, RoutedEventArgs e) { string sourcePath = Directory.GetCurrentDirectory() + "\\PCAngelResources.dll"; //destination path string dllname = textBox1.Text + "_PCAngelResources

问题 I have three BitmapImages that I would like to stitch together to create a composite image. The three images to be stitched together are aligned in the following way: The images are of a type System.Windows.Media.Imaging.BitmapImage. I have looked at the following solution, but it uses System.Drawing.Graphics to perform stitching. I find it unintuitive to convert my BitmapImage to System.Drawing.Bitmap everytime I want to stich them together. Is there a simple way to stitch three images of

问题 hello guys i'm trying to get an image(Frame from resources) to overlay it over the original bitmap. so far i couldn't make my Bitmap goes into the frame as the frame always empty. the original bitmap is now showing inside the frame. here is my code that i'm using to accomplish this. Canvas canvas = new Canvas(); Bitmap border = null; Bitmap scaledBorder = null; border = BitmapFactory.decodeResource(getResources(), R.drawable.frame1); int width = bmp.getWidth(); int height = bmp.getHeight();

问题 I know very similar questions were asked here in the past - but neither had a solution for my problem: I load a image from memory into a BitmapImage: private static BitmapImage LoadImage(byte[] imageData) { if (imageData == null || imageData.Length == 0) return null; var image = new BitmapImage(); using (var mem = new MemoryStream(imageData)) { mem.Position = 0; image.BeginInit(); image.CreateOptions = BitmapCreateOptions.PreservePixelFormat; image.CacheOption = BitmapCacheOption.OnLoad;
