How to change processing image dimension in GPUImage

[SrinivasPeriyasamy]

I'm tired to capture an image from GPUImageStillCamera and I got an image which has dimension 2592 X 1936 and 5.1 MB in size(and the image taken in iPad mini). This is too large(for my app). How to reduce the image dimension while capturing an image?

Set -forceProcessingAtSize: on the first filter after your camera. You can set it back to 0 (unrestricted) after the photo has been captured.
