Converts images to ASCII art. Splits images into boxes of pixels, calculates mean brightness of box, and assigns a character based on a hardcoded mapping.
lein run <filename> [<pixels-per-character>]
Note that currently the file must reside on the classpath.
Output is saved to <filename>.txt in working directory.
Try running on included PNG:
lein run sample.png
This takes
and produces the below art.

- support usage as library
- tests
- better command-line usage (e.g. output file name)
- more options for sizing output
- options for calculating brightness
- options for sampling/calculating brightness
- normalize brightness before assigning characters
- configure brightness->character mapping
- optionally use ANSI colors?
- match character shapes to boxes of pixels
