Ah, so you can handle source code?

Way back in 1994 I tried several times to tempt somebody to produce
executables for MS-DOS from the following material which contains
source code for Ascii Art Tools allowing rotation of existing Ascii
art pictures.

Does the project appeal to you?

I have never been successful in using compilers to compile
executables from source code. I always end up with too many errors I
cannot fix.


Here is the old posting containing the material:

Here's a short collection of Unix utilities for manipulating
ASCII pictures.

Contents:

asciitool.c - Source posted in parent article, somewhat
debugged. Does "raw" flips (no remapping)
lr              - /bin/sh script that flips ASCII left to right
                and maps character shapes (eg, [ --> ] )
                Here's a legal blurb from lr:

# Copyright (C) 1994 by Jef Poskanzer.

# Permission to use, copy, modify, and distribute this software and its
# documentation for any purpose and without fee is hereby granted, provided
# that the above copyright notice appear in all copies and that both that
# copyright notice and this permission notice appear in supporting
# documentation.  This software is provided "as is" without express or
# implied warranty.

tb              - Similar utility that does top-bottom flipping
                Requires asciitool
cw90            - Does clockwise 90 rotations. Requires asciitool
ccw90           - Does counterclockwise 90 rotations. Requires asciitool

The four shell scripts are rather simple. They simply use
asciitool (lr uses "rev", actually) then use tr to process the
output through a mapping of characters.

Syntaxes:

asciitool -{mh|mv|r90|r180|r270} [Infile [Outfile]]
   -mh          Mirror horizontally
   -mv          Mirror vertically
   -r90         Rotate 90 degrees counterclockwise
   -r180        Rotate 90 degrees counterclockwise
   -r270        Rotate 90 degrees counterclockwise

lr [Infile]
tb [Infile]
cw90 [Infile]
ccw90 [Infile]

(Infile defaults to standard input, Outfile defaults to standard output)

For example:

lr picture | tb > picture_rotated_180_degrees
cal | asciitool -r90

Note: None of these utilities rescale images or attempt to do
anything beyond the scope of a single character cell. So rotated
images are almost always going to be extremely distorted.

Examples: ($ is my prompt)

And here's the collection itself. tar.gz.uu format, so:

(1) save the "begin" line and anything following it to asciitools.tar.gz.uu
(2) type uudecode asciitools.tar.gz.uu
(3) type gunzip asciitools.tar.gz
(4) type tar -xf asciitools.tar

You'll have an asciitools/ directory. cd into it and type:
        cc -o asciitool asciitool.c
