First of all, sorry for asking a question not actually directly related to DataObjectManager. I'm asking here because this is the place where I'm actually likely to get an answer. I'm in the situation that I need to do some image manipulation that's not included in SilverStripe.
I have been reading the GD and Image classes but so far I haven't been able to find a way to simply get the file/GD resource from them, do my manipulation and then return it. Optimally I want SilverStripe to treat my new image in the way it treats thumbnails and the like so I actually still have the old image but also have access to the my modified image.
If anyone knows how to go about this I would very much like to hear from you!
Once again, I'm sorry for asking here but I'm kind of desperate.
