Is there a command-line program that can convert an image to ascii art and then save that output as an image e.g. jpg or png?

To illustrate what I'm in need of, I want to convert the image below into ascii art enter image description here

The output that I desire from a program should be similar to this one, which was created by taking a screenshot of the output of an image-to-ascii converter (the output was pure text)

enter image description here

I'm aware that GIMP has the ability to save an image as ascii art and aview can also convert an image to ascii. However, the former cannot be done via the command line and the latter only lets you view the output, not save it (I don't want to resort to taking a screenshot of the output).

I'm also aware that libcaca can save its output to an image, but it only outputs colourful ascii, like below.

enter image description here

Made by converting the source image to greyscale and then with the following command:

img2txt -W 70 -f tga input.jpg > output.tga

The reason for wanting a command-line program is to batch process a folder full of images.

Change the image to black and white before using libcaca? –  Bert May 21 '13 at 13:55
    
Everything you can do in GIMP can be done from command line. –  Oleg V. Volkov May 21 '13 at 15:19
    
@OlegV.Volkov Can you tell me exactly how to accomplish this task? –  hellocatfood May 22 '13 at 6:41
    
No, I can't tell you exactly, because it I only used GIMP's Scheme based scripting a few times and figuring proper API for your question would take just too much time for me right now. I can direct you to relevant docs though: docs.gimp.org/en/gimp-concepts-script-fu.html. –  Oleg V. Volkov May 22 '13 at 8:54
    
@Bert I tried using a greyscale and black/white image. It occasional still renders to a colourful output and still uses coloured/shaded tiles as a background. I want it in pure ascii, which just uses b/w text –  hellocatfood May 22 '13 at 21:38

When you say you don't want to resort to taking a screenshot, do you mean that you don't want to have to resort to taking a screenshot manually? Generating images with aview and taking screenshots of the results could be automated. For example:

#!/bin/sh

aview $1 &
pid=$!
sleep 1 # Give aview time to map its window.
xwd -name "aa for X" | convert - $2
kill $pid

Thanks! That works well. –  hellocatfood Jul 18 '13 at 10:54
