How to apply an openGL filter effect to one texture and save it

  

I m under Delphi and I would like to offer to end user the ability correct a little their picture (light, contrast, color, etc) before uploading them in the app. Visually this is quite easy to do with TfilterEffect component (openGL filter), however how to save the resulting picture ? I need to save in the same size as the original picture, so screen capture can’t work

Also is their any libraries that work under IOS and Android that help to do this ?
