derasterize VS chafa

Far far better than caca.

The subset of usable characters (glyphs) roughly defines how accurate the picture can be represented: if all you have is - and _ and you want to represent an horizontal pipe, it'll be ugly.

Of course it's more complicated than that, but caca uses ascii, while chafa uses a larger unicode range.

The example is illustrated in picture on https://github.com/csdvrx/derasterize where the left is the original basicidea.c using only unicode halfblocks, and the right has more candidate of different shapes.

Derasterize lets you select the width of the range you want to use, to improve encoding time say for video - but ideally, you would be able to test that whatever font you are using contains the glyphs you want.

She's not only done work with sixels but she's the maintainer of the highest quality tool for rendering images as unicode blocks. https://github.com/csdvrx/derasterize

On the application side, there is as yet exactly one terminal multiplexer that can handle images inside multiple terminals, but someone (saitoha?) did make a dev branch of tmux that could do it. /u/csddvx has I think the most recent version of that ; and her derasterize can make sixel work with non-sixel terminals which is a really neat trick.

Example in Windows Terminal:

Like some people here and under this post said, I like Kitty and would recommend it to anyone who uses/used Alacritty, as they are very similar in surface. I actually switch between Alacritty and Kitty pretty often, depending on my "mood". I recently went back to Kitty for image support (through chafa though, for better compatibility across terminal emulators). However, Wayland support is poor and I have some issues with fonts being too bold, although it could just be my config...

If you use a more modern terminal you can also use stuff like:

There's also https://github.com/princejoogie/chafa.nvim, which wraps https://github.com/hpjansson/chafa Did you know about that? I wonder what the differences between your plugin and that one are?

Hello r/Python! I'm here to introduce you to a project I've been working on called chafa.py source. These are Python bindings for the amazing terminal image visualizer Chafa.

this is a plugin that wraps the functionality of chafa into neovim. chafa is a way to display images in the terminal by converting it into ANSI escape sequences.

I guess it is using https://github.com/hpjansson/chafa for that, and it needs to be using https://github.com/seebye/ueberzug/tree/2c55173878906c3b221cdef16cf083f0c412bb58

See also https://github.com/hpjansson/chafa which is an image -> ANSI art library written in C. I built it into my BBS so users can embed images in their posts. Some turn out better than others but it gives the board a unique feel at least.
