GUI apply and reset button?

first

dear friends, I am making an app for photo editing, in which apply and reset button are not working correctly. It is required that after choosing a filter, when apply button is clicked the next filter will apply on the current image. Further, when reset button is clicked the image will rest to the previous filtered image, not the original.

Thanks in advance

Format your code right

Empty line before and after and select entire code and then hit the button C in the small command bar
