There was a utility by Virtual Realities, that converted 320 to 640... You can also do it manually. First go to something like PWGold, load in the picture, go to 640, create a greyscale palette, (use black, white, and some greys for the 6 colors), write down the intensities (darkest to brightes), go to 320 mode, and use the Sort Palettes option, and organize the palette by color number... so if color 3 is has the darkest intensity, set color 3 to the end... when you go back to 640, the picture will look okay... _______________________________________________ _______________ | Steve Chiang Apple //gs Forever! | Coming Soon: | |-----------------------------------------------|---------------| | Columbia University in the Harlem area :P | DreamGrafix: | | Internet : stc7@cunixb.cc.columbia.edu | 3200 color | | America_Online : DWS Steve | power | |_______________________________________________|_______________|
