ANSI art gets its name from its use of ANSI escape codes defined by the ANSI X3.64 standard adopted in 1979.
ĪNSI stands for “ American National Standards Institute,” which is an organization that maintains standards in the United States. ANSI art relies on special terminal control sequences called “ escape codes” (a form of those terminal control codes we mentioned earlier), and that’s where the “ANSI” part really comes in.
The ANSI art palette consists of the 256 characters present in the IBM PC “extended ASCII” character set (also called Code page 437.) In particular, Code allowed a new dimension in text-based art due to its block characters (that could be used similarly to pixels,) gradient blocks for shading effects, and special single-width and double-width lines for drawing boxes and menus.ĪNSI artworks can utilize 16 foreground and 8 background colors as defined by ANSI.SYS in MS-DOS. ANSI art is a special type of computer art that originated on the IBM PC in the 1980s and was used primarily as a way to provide colorful digital illustrations for text-based BBSes.
