Thanks for the heads-up, Alias (and good to hear from you again ;) )
The original attachment's up at http://www.prehensile.co.uk/dropbox/Untitled-1.gif. I'm using the old blur-lots-then-threshold technique. I've done a bit more research, and the way I understand it, most antialiasing techniques work by calculating the sub-pixel positions of things, and setting the brightness of the closest corresponding pixels accordingly. In this case, however, I already have an aliased bitmap with no sub-pixel information. I guess an algorithm could be conceived that would somehow infer sub-pixel values, but this feels like it would be unnecessary faff, and very slow. Anyone know of a quick-and-dirty way of smoothing a bitmap? I guess I could render at a higher resolution than needed and scale down, to mimic calculating sub-pixels, but that also feels inefficient. There must be a clever cheaty way of doing this? h. On 04/02/07, Alias™ <[EMAIL PROTECTED]> wrote:
Can you throw the example image onto a web server so we can see it?
