Image processing img2utf

Overview

img2utf

Transform images to textual line art!

Images require pre-processing to come out nice. It's expected that users will do the following:

Apply gaussian blur to remove noise and details.
Remove the color from the image.
Apply an edge detection algorithm.
Invert the image to see the line art.
Run this program on the image.

Usage is simple: cargo run image.png

Explanation

The program simply runs over the whole image, trying to match a "mask" and then prints the corresponding matching character. Because the characters are chosen to make lines stand out, the result should look better for line-oriented output.

This page was used to gather symbols to use for drawing: https://en.wikipedia.org/wiki/Box-drawing_character .

Examples

Becase web browsers are currently terrible at rendering the output as all monospace, unlike terminals, the examples below have been included as images. If you work for Google or Mozilla or Microsoft or Apple please fix this for the love of god.

How to save output to a png file?

For ASCII art, there is a tool https://github.com/ansilove/ansilove to save the output as a png file. So how to save img2utf output, which contains non ASCII chars, to a png file?

Hi, sorry for the title text vomit, didn't really know what to put as title.

I cloned this repo and tried running cargo run test.png in two environments (Windows 10 x64, WSL1) and they both fail with a similar error.

Rust 1.50.0

With the Windows 10 x64:

I barely have Rust knowledge (I started the book, got distracted, and plan to revisit it soon!) so I'm sorry if it's a simple mistake on my end. I just wanted to test this out.

Help needed: add missing masks!

It's a lot of work to find masks which are missing. If you uncomment the eprintln it'll help you find them. I would greatly appreciate if I could get some help on this.
