All computation is done using long integers, so no floating-point overhead is incurred.
Finally, an enhanced error diffusion algorithm is used to simulate a range of tones on the image. In general, therefore, the simpler the image presented the faster it is drawn. Selecting Sunlight , Starlight , or 3-D all slow down the drawing. The time taken is inversely proportional to the speed of the processor and proportional to the square of the image diameter.
