Hello all! :) I've only started working with AGG but I'm very impressed so far, it is = a remarkably powerful system. If I may be permitted a noobish question: What is the difference between span_image_resample_rgba and = span_image_filter_rgba? I know that span_image_resample_rgba is less prone to moir=E9 when = downsampling, and is slower than span_image_filter_rgba. But I'm not = sure what it actually does to achieve this.=20 Is _resample just _filter with some blur added? Or is there a more fundamental difference between "resampling" and = "filtering" in AGG? I guess I'm a bit confused because I thought the interpolation done when = you use span_image_filter_rgba would already be considered "resampling." = :) I've tried searching on google for other uses of the term but it just = seems to refer to using a filter/interpolation as opposed to simply = using nearest neighbour. - Lorne Laliberte, Software Developer Indigo Rose Software (204) 946-0263 x14 |
