Textual Paint

MS Paint in your terminal.

This is a TUI (Text User Interface) image editor, inspired by MS Paint, built with Textual.

This screenshot of Textual Paint is the terminal's screen buffer copied as HTML, wrapped in SVG, placed in HTML inside Markdown. This might not render correctly in your browser.

  • You could totally use this program over SSH! Haha, this "what if" project could actually be useful. Of course, it should be mentioned that you can also run graphical programs over SSH, but this might be more responsive, or just fit your vibe better.

Development

Install Textual and Stransi:

pip install "textual[dev]" "stransi"

Run via Textual's CLI for live-reloading CSS support:

textual run --dev "paint.py --clear-screen"

Or run more basically:

python paint.py --clear-screen

--clear-screen is useful for development, because it's sometimes jarring to see error messages that have actually been fixed, when exiting the program.

There are also launch tasks configured for VS Code, so you can run the program from the Run and Debug panel.

I tried running via modd to automatically reload the program when (non-CSS) files change, but it doesn't handle ANSI escape sequences well. I wonder if it would work better now with the --clear-screen option. (I could also look for another tool that's more part of the Python ecosystem.)

Unicode Symbols and Emojis for Paint Tools

The first thing I did in this project was to collect possible characters to represent all the tool icons in MS Paint, to gauge how good of a recreation it would be possible to achieve, starting from looks. Unfortunately, I haven't run into any significant roadblocks, so I'm apparently recreating MS Paint. Again.

These are the symbols I've found so far:

• Free-Form Select: ✂️📐🆓🕸✨⚝🫥🇫/🇸◌⁛⁘ ⢼⠮
• Rectangular Select: ⬚▧🔲 ⣏⣹
• Eraser/Color Eraser: 🧼🧽🧹🚫👋🗑️
• Fill With Color: 🌊💦💧🌈🎉🎊🪣🫗
• Pick Color: 🎨💉💅💧📌📍⤤𝀃🝯🍶
• Magnifier: 🔍🔎👀🔬🔭🧐🕵️‍♂️🕵️‍♀️

• Polygon: ▙𝗟𝙇﹄』⬣⬟🔶🔷🔸🔹🔺🔻△▲
• Ellipse: ⬭⭕🔴🟠🟡🟢🔵🟣🟤⚫⚪🫧
• Rounded Rectangle: ▢⬜⬛

The default symbols used may not be the best on your particular system, so I may add some kind of configuration for this in the future.

Cursor

A crosshair cursor could use one of +✜✛✚╋╬, but whilst that imitates the look, it might be better to show the pixel under the cursor, i.e. character cell, surrounded by dashes, like this:

 ╻
╺█╸
 ╹
