ASCII & ANSI Art - The Unix Style - Unix Related Arts & Image Manipulation Software
venam
We should make a list of all the softwares and libraries that specialize in ascii and ansi arts.

I'll do a research on it and report back.

From just a glimpse and personal small knowledge on the subject I could go in the direction of:
cacalib
aalib
figlet & toilet fonts
cadubi
ninjacharlie
After looking around a bit, I found a linux clone of thedraw called duhdraw. It's on AUR if anyone is interested.

I've found some excellent Ascii art tutorial.
I haven't read them all yet (That's gonna be the fun in the weekend).
They discuss specific techniques to create them from scratch.

http://the.sunnyspot.org/asciiart/docs/instruct.html
http://the.sunnyspot.org/asciiart/docs/rowtechn.html
http://the.sunnyspot.org/asciiart/docs/normandt.html

Whoever wanna take the learning curve with me stand up.
It would be cool to have some "professional" ascii-arter on nixers.

I've read them all (I couldn't wait).

Here's a summary:

Code:
Use monospace font

Start with a canvas (a text file filed with spaces)

Characters differences, shades, effects:

Sketching style chars:          / ` " ' \ , . _ - = ~ ^ ; |
More on sketching style:
    / \ | - _ + ( ) < > , . ~ ^ " V X T Y I l L : ` ' ! j J 7
You usually start with those characters when sketching the outline:  / \ | - _ ( )
Then try polish and not leave any gap.
Example:

                   |         |        |        |        |
                   |         l        l.       \        l
                    |         I       `|        Y       `L
                    |         |        |        |        |

                 START       ^----------OPTIONS----------^

Near horizontal lines use those chars:  ~"-.,_
Example:
    __
      "~~"----..,___


Curves in sketchy style with those chars:     / \ - _ ~ " . , ' ` ! I l Y
Example:
                     ___
                 .-~"   "~-.                           /
                /           \                      _.-~
               Y             Y                   ,^
               |             |                  /
               l             !                 /
                \           /             __.-~
                 "-.,___,.-"

                   CIRCLE                SUBTLE CURVATURES

A note on intersections:
[quote]
    I also consider the choice between "." an "," important because it
    affects the smoothness of the line. For example, in the part on the
    above curve: _.- :it looks like a "," may have been a better choice:

                      /             But as you can see here, using the
                  _,-~              comma has altered the flow of the
                ,^                  line somewhat. It now appears as
               /                    more of a "step" rather than an
              /                     angled line.
          _,-~

        CURVE USING COMMA

    Intersections require yet another strategy. Often you'll find that one
    line must join onto another at a place where the join isn't neat:

        "-._ /         "-._ /           Here the incoming line should join
            /              7            onto the main part halfway through
           /              /             a "/". That's where you can use some
                                        other chars. In this example, a "7"
     INTERSECTION        FIX            would work well, as seen in the
                                        example to the left.

    You could also try "Z" "X" "T" "Y" as a replacement, but it depends
    entirely on what is happening around that point as to which char works
    the best. Other chars which work well in these situations are "K" "<" ">"
    "r" "L" "j" "J" and "I" because they all point in at least 3 directions.

Solid Art Style:

Filled look chars:           @ # $ & X % > / ; :
Subtilities chars:         S $    : ;    % X    0 O
Pay attention to uppercase and lowercase:         S s    X x    O o   @ a
Example of decreasing and increasing lines:
        Ss,..,sS          or    -=*@*=-     or     .,%,.
        SSss,,..,,ssSS    or    ..,,;;|;;,,..
[quote]
    By using a "heavy" character such as: W M H 8 :you build up a basic
    silhouette (filled in outline)
[/quote]
Heavy characters and lighter ones create a contrast.

Then the same, you polish.
[quote]
    Once the basic shape is defined with the chosen character, the anti-
    aliasing process is next. The most used chars are:

    d b P F 9 V T Y A U _ , . - * ^ ~ " ` ' n a o l L j J k [ ] ( ) : \ / | !
[/quote]
[quote]
    Going back to the earlier "curve" examples, here they are in solid form:

                  .adAHHHAbn.                           JHH
                 dHHHHHHHHHHHb                      _.adHHH
                dHHHHHHHHHHHHHb                   ,AHHHHHHH
                HHHHHHHHHHHHHHH                  dHHHHHHHHH
                VHHHHHHHHHHHHHP                 JHHHHHHHHHH
                 YHHHHHHHHHHHP              _.adHHHHHHHHHHH
                  "^YUHHHUP^"              HHHHHHHHHHHHHHHH
                      "~"
                    SPHERE                   CURVED HILL

    It's important to get a good understanding of how best to use the
    characters. The basic forms are as follows:

          _,.aomdAHAbmon.,_     For the upper curves.

            "~^*YUHUP*^~"       For the lower curves.
[/quote]

Solid artworks have outer edges.
The characters used to smoothen them are:
[quote]
    Good "outer" characters are:    . , : ; ' `
    For the transition from solid to outer edge:   I H A U V T Y | i j d b
    n a o [ ]   :or basically anything that produces the desired effect.
[/quote]


---

Remember that characters have different position on the line, they can be used
as bridges with the line above or under.

Size of the art:

Smaller is harder, gives space to the imagination and needs more details.
[quote]
    Remember, shape is the most important aspect of small ascii art.
    ...it's not always necessary to be that detailed,
    it is more important to focus on making the object immediately
    identifiable.
[/quote]
Bigger is easier but annoying on the screen.

Visualizing:
After a fast sketch, which consist of just drawing the boundaries.

[quote]
Afterwards I'll go through and
add the highlighting, shading, and other detail work that I want.
Sometimes when you're sitting so close to the screen, tapping in the
pictures, NOTHING you do looks right.  If that's the case, stand back
from the screen.... Or squint your eyes.  Or if you wear glasses, take
them off for a moment.  Many times you'll see the picture "come
together" when you try one of these little tricks.
[/quote]

Or resizing:
[quote]
In reduced format the text is actually transferred in graphics so
that an '8' would actually appear as a black square.  This gave the
picture a rough look; the edges were all jagged.  But, by
experimenting with various character changes I soon realized that
I could smooth out those jagged edges.  I spent a lot of time
flipping back and forth between the normal and the reduced views.
[/quote]


About smoothing (or polishing):
[quote]
The whole thing is visual as you could have guessed.  So, the best
way I know to show you what I mean is by giving an example:


     Take this                     Doesn't this
     for example                   look smoother?

      8                              8
      88                             Yb
       88                             Yb
        888                            Y8a,
          88888                         `"Y888


BTW, that reminds me of a quote I saw not too long ago:  "A truly
wise person does not play leapfrog with a rhinoceros"  :-)

I consider the "smoothing problem" as nothing more than a "weight
distribution problem".  By shifting up the pixel density of an 8
with characters such as P, Y, ", etc., where necessary, and by
shifting down the pixel density of an 8 with characters such as b,
d, a, etc., where necessary, the graphic takes on a smoother look.

When choosing a picture:
You can start by drawing over it the highlight and main lines.

honestly, i do my ansi in the same editor i do everything else in, vim.

i mostly use the digraphs or a box drawing/shading cheat cheat/pallet. (learn more: curl gopher://z3bra.org/0/notes/vim/digraphs.txt)

16colors is working on a webeditor
http://draw.sixteencolors.net


oh, you're looking for tutorials?


also, if you just go on youtube and search "ansi is dead", blocktronics just did a cool prod where their members recorded their drawing sessions. some cool tricks to be learned there.

some scholarly info?

This thread made my year.
venam
This is gonna be my weekend project: Spend my time applying the ascii-art techniques and try to come up with a new robot for my collection.

I won't try the ANSI art yet.

Couldn't wait, I had to try things out a bit.
It's super fun.
I took a picture, drew the outline with a thick line and made the terminal transparent.
Now I'm just following the tips I've posted above.

Awesome thread and great resources. No artist here, but it makes me wanna try to make some ansi art myself.
Adrift
Offtopic but, Venam, which terminal emulator are you using? If you're still using urxvt how did you make transparency work with 2bwm?
