NET Standard library referenced by the individual platform projects. The second way to load a bitmap is by including the bitmap as an embedded resource in the. The Decode method must determine the format, and then decode the bitmap file into SkiaSharp's own internal bitmap format.Īfter your code calls SKBitmap.Decode, it will probably invalidate the CanvasView so that the PaintSurface handler can display the newly loaded bitmap. The SKBitmap.Decode does a lot of work: The Stream object passed to it references a block of memory containing an entire bitmap in one of the common bitmap file formats, generally JPEG, PNG, or GIF. Android does not allow the Stream from HttpClient to be processed by the main thread except in asynchronous methods. Notice that the Stream object obtained from GetStreamAsync is copied into a MemoryStream. Using (MemoryStream memStream = new MemoryStream()) Using (Stream stream = await httpClient.GetStreamAsync(" When using HttpClient with iOS and Android applications, you'll want to set project properties as described in the documents on Transport Layer Security (TLS) 1.2.Ĭode that uses HttpClient often involves the await operator, so it must reside in an async method: try A single instance of the class can be defined as a field: HttpClient httpClient = new HttpClient() In the following three code examples of loading a bitmap, the class is assumed to contain a field of type SKBitmap: SKBitmap bitmap Īs the article Bitmap Basics in SkiaSharp stated, the best way to load a bitmap over the Internet is with the HttpClient class. Those techniques are discussed in the articles Creating and Drawing on SkiaSharp Bitmaps and Accessing SkiaSharp Bitmap Pixels. It is also possible for a SkiaSharp application to create a new bitmap, and then draw on it or set the bitmap bits algorithmically. From a resource embedded in the executable.Loading a bitmapĪ bitmap used by a SkiaSharp application generally comes from one of three different sources: From the home page of that application, choose SkiaSharp Bitmaps, and then go to the Displaying Bitmaps section. Samples on this page are from the SkiaSharpFormsDemos application. The DrawBitmapLattice and DrawBitmapNinePatch methods are discussed in the article Segmented display of SkiaSharp bitmaps. This article reviews the techniques to load bitmaps and goes deeper into the use of the DrawBitmap methods of SKCanvas. That article showed three ways to load bitmaps and three ways to display bitmaps. WPF Localization - StringFormat for Formatting Cur.The subject of SkiaSharp bitmaps was introduced in the article Bitmap Basics in SkiaSharp.WPF - Editable ComboBox with DataTemplate.WPF - Image Format Conversion (Including Gray Scal.WPF - Saving Application Memory by Specifying Deco.
