Ok. But is there a way to limit pallette to 16 colors / 32 colors (using some kind of estimation, rounding, etc.).
I used PNG because the incoming stream is of text editors and GUIs not forest/movie like scenes. But now I am now open to using other formats such as JPEG or GIF, etc. whichever gives least size at native resolution. Happy New Year, thanks.
