带有imageFromCurrentlyProcessedOutput的GPUImagePicture无法获取UIImage [英] GPUImagePicture with imageFromCurrentlyProcessedOutput doesn't get UIImage

问题描述

我正在使用GPUImage处理本地照片，正在使用它进行初始化:

I'm using GPUImage for processing a local photo, I'm using this to initialize:

localImageSource = [[GPUImagePicture alloc] initWithImage:selectedImage];

然后我添加过滤器，然后我可以在屏幕上看到它.

Then I'm adding the filters and I can see it on the screen.

问题是我需要UIImage来保存它，但是当我打电话时:

Problem is that I need UIImage to save it but when I call:

[localImageSource imageFromCurrentlyProcessedOutput]

我什么也没得到.

请帮助！

推荐答案

使用过滤器本身调用显然可以解决此问题:

Calling that with the filter itself apparently solve this problem:

[filter imageFromCurrentlyProcessedOutput];
