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.
ASCII art of a fish. ASCII art is a graphic design technique that uses computers for presentation and consists of pictures pieced together from the 95 printable (from a total of 128) characters defined by the ASCII Standard from 1963 and ASCII compliant character sets with proprietary extended characters (beyond the 128 characters of standard 7-bit ASCII).
Python Imaging Library is a free and open-source additional library for the Python programming language that adds support for opening, manipulating, and saving many different image file formats. It is available for Windows, Mac OS X and Linux. The latest version of PIL is 1.1.7, was released in September 2009 and supports Python 1.5.2–2.7. [3]
Data in a RAW-file is structured according to the Bayer filter's pattern in cameras that use a single image sensor. Debayering, the process of obtaining bitmap data from a RAW-image is always a lossy operation. [citation needed] In addition, some downsampling is always performed, again reducing image information.
cowsay is a program that generates ASCII art pictures of a cow with a message. [2] It can also generate pictures using pre-made images of other animals, such as Tux the Penguin, the Linux mascot. It is written in Perl. There is also a related program called cowthink, with cows with thought bubbles rather than speech bubbles.
ASCII was incorporated into the Unicode (1991) character set as the first 128 symbols, so the 7-bit ASCII characters have the same numeric codes in both sets. This allows UTF-8 to be backward compatible with 7-bit ASCII, as a UTF-8 file containing only ASCII characters is identical to an ASCII file containing the same sequence of characters.
The image data is encoded as a comma-separated list of byte values, each written in the C hexadecimal notation, '0x13' for example, so that multiple ASCII characters are used to express a single byte of image information. [5] XBM data consists of a series of static unsigned char arrays containing the monochrome pixel data.
Other than ASCII-to-hex converted comments in S0 header records, the SREC file format doesn't officially support human-readable ASCII comments, though some software ignores all lines that don't start with "S" and/or ignores all text after the Checksum field (thus trailing text is sometimes used (incompatibly) for comments).
