Yes, I don't know the exact algorithm of the StretchBtl from WINAPI, but the result by it looks a little bit crappier than to copy every Nth pixel.I've seen many sh***y things coming from MS through the years, but I you really saying that their stretch (down) algorithm is worst than "copy every Nth pixel"??? This is something I'll have to see before my eyes ;-)
Look here the difference in my little game Robot:
Copy every Nth pixel: http://www.az2000.de/downloads/own_stretch.png
WINAPI: http://www.az2000.de/downloads/ms_stretch.png
GTK: http://www.az2000.de/downloads/gtk_stretch.png
This is interesting. Is the WINAPI StretchBtl affected by this?BTW, there's a WinAPI function to set the stretch quality... I don't remember its name right now, unfortunately :-(
