bitmapimage

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; image.UriSource = null; image.StreamSource = mem; image.EndInit(); } image.Freeze(); return image; } And

How to get BitmapSource from BitmapImage? Or how to convert BitmapImage to BitmapFrame directly? It seems to me that if I have BitmapSource I could use BitmapFrame.Create and finally get BitmapFrame object from given BitmapImage A BitmapImage inherits from BitmapSource so no conversion is needed The BitmapImage inherits from BitmapSource as parapura said. Example: BitmapSource bitmapSource = new BitmapImage(); BitmapImage bitmapImage = bitmapSource as BitmapImage; Source: BitmapSource MSDN 来源： https://stackoverflow.com/questions/8138610/how-to-get-bitmapsource-from-bitmapimage

How can I get a list of image formats supported by System.Windows.Media.Imaging.BitmapImage? I am writing a simple image processing tool in C# WPF. The BitmapImage class is one of the more useful bitmap classes as it is able to decode from a wide variety of formats. In particular, it is able to open NEF (Nikon's RAW format) on my computer. It is likely that BitmapImage can open a wide variety of RAW formats from other manufacturers, a function I am keen to make use of. As I don't know every format that can be opened as a BitmapImage, I am currently using a try/catch to try and construct a

Does anyone know how to scale the bitmap image without losing the image quality ? Currently I facing this problem , where the size of selected image maybe too big caused the app return to another activity. So now I tried using this method to scale the selected image without losing its quality. I get the code from here . protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); switch (requestCode) { case RESULT_LOAD_IMAGE: if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK & null != data) { Uri

I'm trying to pass some representation of an image back and forth between Silverlight and a WCF service. If possible I'd like to pass a System.Windows.Media.Imaging.BitmapImage , since that would mean the client doesn't have to do any conversion. However, at some point I need to store this image in a database, meaning the image representation must be able to convert to and from byte[] . I can create a BitmapImage from a byte[] by reading the array into a MemoryStream and using BitmapImage.SetSource() . But I can't seem to find a way to convert the other way - from BitmapImage to byte[] . Am I

I was looking for a tutorial where is described how to write/read hidden text into image file using C#, but unfortunately I din;t find any good posts about this, so I decided to ask here about this small trick. Suppose I have an image file called test.jpg , is there any way to write an hidden text like "Hello word " to this file ? I have read about image metadata , and I suppose that I should try to write somehow to this metadata , but I din;t find how. If anybody know how to do it , please help me to understand how to it. Thanks. The correct term for this is "Steganography". The following

I'm loading an image in WPF by using the BitmapImage class. My code works perfectly when I give an absolute path for the UriSource but not when I try and use a relative path. My XAML is: <Image Width="50" Name="MemberImage" HorizontalAlignment="Left"> <Image.Source> <BitmapImage DecodePixelWidth="50" UriSource="questionmark.jpg" /> </Image.Source> </Image> The questionmark.jpg is added to the project with a Build Action of Resource and Copy to Output Directory set to Copy always. The error I get is "The file [file name] is not part of the project or its 'Build Action' property is not set to

I have 2 images and I want to merge them into one on my apps in Windows Phone. The first image captured by my WP's camera, the second image is a frame (borders, filter, etc.) which user can choose among our templates. So how can I merge them into one. Thanks and best regards. Agung Pratama I don't quite understand what you ask. But I guess you want to overlay 1 image on top of another. If so, there is already an answer here . Inside the <grid> , you can provide both the image, and customize the opacity of each image to make it overlay-ed. EDITED: You can use Writeablebitmap for that and there
