Ascii-Art Picture Rotation Tools.
Here's a short collection of Dos utilities for manipulating ASCII pictures.
LR.BAT - flip ascii-art picture left-right
TB.BAT - flip ascii-art picture top-bottom
CW90.BAT - rotate ascii-art picture 90 degrees
CCW90.BAT - rotate ascii-art picture 270 degrees
The four Dos scripts are rather simple. They use ASC-TOOL.EXE then
use TR-386.EXE to process the output through a mapping of characters.

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:

# that the above copyright notice appear in all copies and that both that

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.

Installation
-=O[ Instructions to install Ascii-Tools ]O=-
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- unzip ASC-TOOL.ZIP to a directory (eg. C:\AT)
- add the directory (eg. C:\AT) to your PATH environment variable
if you wish to run the batch-files from any location.
- run the batch-files from the Dos prompt.
eg. lr <infile> <outfile>
Information
-=O[ Brief Description of how these tools work ]O=-
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The batch-files first call ASC-TOOL.EXE to perform raw flips and
rotations of ascii-art pictures,
like this :-
type test1.asc
}}---}
asc-tool -mh test1.asc
}---}}
The output from ASC-TOOL.EXE is then piped to TR-386.EXE which re-maps
(translates) the characters according to two sets of characters supplied
as parameters.
The first set are characters to be re-mapped and the second set are the
characters that the first set will be re-mapped to, in positional order,
like this :-
type test2.asc
}---}}
tr-386 "}" "{" test2.asc
{---{{
tr-386 "-}" "={" test2.asc
{==={{
The resulting output from TR-386.EXE may then be piped to SED-386.EXE
which simply strips any trailing space characters, using the command
sed-386 "s/ $*//"
Note: Trailing space characters in a document could be removed using
the command :-
sed-386 "s/ $*//" document.txt >doc-stripped.txt
SUMMARY
~~~~~~~
Thus the process is :-
type %1; asc-tool -mh %1 | tr-386 "-}" "={" | sed-386 's/ $*//'
}}---} }---}} {==={{
