There are versions of GetImage that take a pointer to an Image so you can allocate your own image data structure (once using new HSLImage() then set the size) and use it over and over again. This will be a bit faster. When programming in a real-time environment it is better to NOT be doing memory allocations or formatted output in loops where you hope to have deterministic (execute in the same amount of time each time through) performance.
