这使得类更易于用于构造 UI,因为它们具有一组默认的受支持的源文件格式和解码行为。 BitmapImage 等类将一些解码选项和逻辑公开为 ImageOpened 或ImageFailed 事件的事件数据的一部分。 如果需要高级图像文件解码或图像编码,则应使用 Windows.Graphics.Imaging 命名空间中的 API。 如果你的应用方案涉及图像文件格式转换...

在Windows Forms中,重绘位图通常是通过继承自System.Windows.Forms.Control类的自定义控件来实现的。通过重写控件的OnPaint方法,可以在需要的时候进行位图的重绘操作。在OnPaint方法中,可以使用System.Drawing命名空间中的绘图类(如Graphics、Pen、Brush等)来绘制图形、文本和其他元素。
