the filter part, my origin

the filter part, my origin image size is 640x480, then I use the script to crop it to 100x100.

after I crop the image and apply the GPUImageSwirlFilter, the return image doesn't correct and also the size is getter bigger than 100x100.

the GPUImageSwirlFilter work fine on any origin image.

here is the filter script

GPUImageSwirlFilter *filter = [[GPUImageSwirlFilter alloc] init];
UIImage *output = [filter imageByFilteringImage:UIImage];

What part of this is wrong?

What part of this is wrong? The UIImage cropping or the filter? If the filter, what's the input size, output size, and code you use to run the filter?
