MonoTouch中CGImageCreateWithImageInRect的等价物是什么？

Question

MonoTouch中CGImageCreateWithImageInRect iOS方法的等价物是什么？

我想在C#中转换这个Objective-C行:

CGImageRef sampleImageRef = CGImageCreateWithImageInRect(self.CGImage, fillRect);

提前致谢!

所述CoreGrapphics功能CGImageCreateWithImageInRect对应WithImageInRect的方法CGImage.API签名是:

public CGImage WithImageInRect (RectangleF rect)

从ObjectiveC翻译后,您的源代码应如下所示:

 CGImage sampleImageRef = this.CGImage.WithImageInRect (fillRect);
