Today, as perhaps implied by the post title, is World Braille Day, celebrating the writing system on Louis Braille’s birthday.

Braille

On with the code!

Picture to Nonogram

I finished the most basic version of the program. At the end of the run, there’s a grid for comparison purposes, the runs of dark pixels by row, and the runs of dark pixels by column. An example of the latter two follows.

[
  [ 16 ],      [ 7, 8 ],
  [ 7, 8 ],    [ 6, 7 ],
  [ 7, 7 ],    [ 4, 1, 3 ],
  [ 3, 5, 3 ], [ 3, 9, 2 ],
  [ 3, 9, 2 ]
]
[
  [ 9 ],    [ 9 ],    [ 9 ],
  [ 6 ],    [ 5, 2 ], [ 5, 3 ],
  [ 3, 5 ], [ 1, 3 ], [ 3, 3 ],
  [ 5, 3 ], [ 5, 2 ], [ 5, 2 ],
  [ 5, 2 ], [ 7 ],    [ 9 ],
  [ 9 ]
]

That’s enough information to solve the puzzle, but I doubt it’s enough information to even begin to guess what the source image might have been. It’s a decent start.

Anyway, I also added some code to enforce a minimum size to the grid—since passing in a square image produces a 1x1 image, which fails to be useful—and did some minor refactoring.

Library Updates

My generic board game code (that hasn’t actually happened) needed a library bumped, so I took care of that, too.

Next

I want to also find a way to set a maximum size of images, since a 1921x1080 image is more than a bit unwieldy. This should probably push out to an actual puzzle to solve, including grabbing a random (Free Culture) image to process, too. It also might not be a bad idea to find a way to (usefully) iterate over the transformation to monochrome, to test with different values to get a puzzle that’s likely to be fun.
