You are right about this - it is situational. However, if one is concerned with performance and processor load, vectors fail at any mild level of complexity compared to bitmaps.
An image with irregular detail can still, most always (unless every pixel is different) be compressed down to a smaller form. It most certainly has less processor overhead (maybe not memory). -j On Sep 17, 2012, at 5:29 PM, Paul Andrews <p...@ipauland.com> wrote: > On 17/09/2012 22:10, Jon Bradley wrote: >> Just look up the storage and memory needs of a vector point (plus it's >> animation) and compare that to an RGB triplet. >> >> It's pretty easy to find what you are looking for. > > I don't think it's easy at all.
