Hi Csongor,
Well, there's magic...
Sorry, couldn't resist. Obviously this work has to be done SOMEWHERE.
So, even if you could just pass it off to another class, possibly JAI as you
mentioned previously, something like that is getting done. Is it more
elegant to pass to a hidden ugly routine than to have it locally?
There are always things that can be done to make this smarter. For
example, you could do everything in one buffer; you could have the buffer
the size of the viewport view only, handling redraw and scrolling yourself.
You could have a buffer only the size of a raster row and really save
memory.
You could any number of things and, as usual, there are tradeoffs for
each. I've found over time as a developer and consultant that what I call
'choosing the best efficiency' can be the most important thing I contribute.
The answer I gave is probably the easiest of the more efficient ( in terms
of time, effort, memory and performance ) ones. I usually step through:
'Is that Good Enough?' No? Next step.
