Right now, it is: -O0: normal conversion (default) -O1: convert polygons to bitmaps, text to text (-s poly2bitmap) -O2: convert everything to bitmap (-s bitmap) I'm thinking about shifting -O1 to -O2 however, so that -O1 is --flatten, so we would have: -O0: normal conversion -O1: normal conversion + --flatten (reduce clippings) -O2: convert polygons to bitmaps, text to text -O3: convert everything to bitmap Hope this shift won't cause confusion. Right now, however, -O1 and -s poly2bitmap is equivalent. > If it is so, I observed that using "-O1" to convert a complex PDF page > (using 14052008 snapshot) is rather slow (can take up to 4-5 minutes for a > page) as compared to using "-s poly2bitmap" in an older version (using > Dec2007 snapshot). That's true. That's because the implementation got improved (generates less bitmaps than the Dec2007 snapshot). If I get around to it, I'll optimize the conversion speed. (It's possible to speed it up by factor 3-4) Greetings Matthias
