I have no idea what you are asking here.

GPUImageExposureFilter exposureFilter = [[GPUImageExposureFilter alloc]init]; exposureFilter.exposure = global.num 0.01; [exposureFilter forceProcessingAtSize:CGSizeMake(3024, 4032)];

[picture addTarget:exposureFilter];
[exposureFilter addTarget:outputView];

[picture processImage];

[exposureFilter useNextFrameForImageCapture];

When I set up an exposure filter like this, enter the picture, which is the size of 3024x4032. But in the above outputView to receive the image size is 640x854, and I set up a forceProcessingAtSize:, is my code error? or else can set the output image size of 3024x4032 on outputView.
