What is the equivalent of CGImageCreateWithImageInRect iOS method in MonoTouch?

我正在尝试在C#中转换此Objective-C行:

I'm trying to convert this Objective-C line in C#:

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

提前谢谢！

推荐答案

CoreGrapphics函数 CGImageCreateWithImageInRect 与 CGImage 的 WithImageInRect 方法相对应.API签名为:

The CoreGrapphics function CGImageCreateWithImageInRect correspond to the WithImageInRect method of CGImage. API signature is:

public CGImage WithImageInRect (RectangleF rect)

从ObjectiveC转换后，您的源代码应如下所示:

Once translated from ObjectiveC your source code should look like:

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