SKBitmap bitmap; 正如SkiaSharp 中的位图基础知识一文所述,通过互联网加载位图的最佳方式是使用HttpClient类。 类的单个实例可以定义为一个字段: C# HttpClient httpClient =newHttpClient(); 在iOS 和 Android 应用程序中使用HttpClient时,需要按照传输层安全性 (TLS) 1.2文档所述设置项目属性。

A SkiaSharp bitmap is an object of typeSKBitmap. There are many ways to create a bitmap but this article restricts itself to theSKBitmap.Decodemethod, which loads the bitmap from a .NETStreamobject. TheBasic Bitmapspage in theSkiaSharpFormsDemosprogram demonstrates how to load bitmaps from ...
