Hello List I'm in the middle of writing a fairly complex painting application (something like photoshop, but with only the base paint tools). I'm using quartz composer for the main paint tools. One issue has cropped up though, and that's filtering.
I have a zoom + pan tool, so the artist can zoom in on a particular area for detail editing. It works fine, by rendering to a billboard and using the billboard size/position to do the zoom/pan functions, but of course the resized image is bilinear filtered, and gets blurry when zoomed in. Is there any (nice) way to do this but have nearest neighbor filtering, so I get big chunky pixels instead of a blurry mess? At the moment I'm using an intermediate stage, rendering in the image inside a render-in-image set to 32bit, as 32bit modes don't support filtering. It works, but it has a definite performance hit, and I suspect it's not going to be futureproof at all. Thanks Chris
