An example Wikipedia logo generated using libcaca 0.99.beta18. libcaca is a software library that converts images into colored ASCII art.It includes the library itself, and several programs including cacaview, an image viewer that works inside a terminal emulator, and img2txt, which can convert an image to other text-based formats.
AAlib is a software library which allows applications to automatically convert still and moving images into ASCII art. It was released by Jan Hubicka as part of the BBdemo project in 1997. It was released by Jan Hubicka as part of the BBdemo project in 1997.
In some cases, the entire source code of a program is a piece of ASCII art – for instance, an entry to one of the earlier International Obfuscated C Code Contest is a program that adds numbers, but visually looks like a binary adder drawn in logic ports. [17] Some electronic schematic archives represent the circuits using ASCII art.
The more typical use is to encode binary data (such as an image); the resulting Base64 data will only contain 64 different ASCII characters, all of which can reliably be transferred across systems that may corrupt the raw source bytes. Here is a well-known idiom from distributed computing:
Filesize reduction factor 100 or so when converting to png is typical if the image is a line drawing; if the image is a photo, it is best converted to jpeg, which yields a greater filesize reduction. The PPM format is generally an intermediate format used for image work before converting to a more efficient format, for example the PNG format ...
The ASCII History of Art for the Blind is a webpage that describes selected images verbally by reading each of the ASCII characters that make up the image through an automatic recordings. War is a collection of files stored with images taken in front of a TV screen in 1999, recording the events that took place during the NATO bombing of Yugoslavia.
In the table below, the column "ISO 8859-1" shows how the file signature appears when interpreted as text in the common ISO 8859-1 encoding, with unprintable characters represented as the control code abbreviation or symbol, or codepage 1252 character where available, or a box otherwise. In some cases the space character is shown as ␠.
Data conversion is the conversion of computer data from one format to another. Throughout a computer environment, data is encoded in a variety of ways. For example, computer hardware is built on the basis of certain standards, which requires that data contains, for example, parity bit checks.
