Im a programmer I am using SpriteLib, I need for OGL programming to create mask of these bmp. These consist of black and white ( two colors ) images. The paint program I am using for my art currently is Jasc Paint Shop Pro 4.0 . But when I decrease the color depth, I do not get clear, sharp result like I need. The resulting images makes for some not so sharp lines where dark greys where involved for example but I need that every black pixel stays purest black and every other pixels gets to purest white. Anyway to do this ? Is there a particular paint program that can do this ? Any help or suggestions would be appreciated. WHO DO THEY THINK THEY''RE FOOLING : YOU ?
