hi! i'd like to perform special filtering algorithms that requires to access to the full image while rendering via engine(). i know i can request the full tile, but i read in the docs that it might be slow and should be avoided. so what's the best approach if i need to know the current image while rendering my rows via engine()?
i am also thinking about requesting a full tile only when the frame number has changed and work with simple rows only while the frame number remains constant. this might at least give some speed enhancement while playing around with the parameters. what do you think? Thanks! Pieter
