https://rosettacode.org/wiki/Bitmap#ATShttps://rosettacode.org/wiki/Bitmap#ATS
I went back to doing things at a low level, which my readers surely will appreciate. So the code is lengthy, given what is being done.
And safety is important, so notice that if a ‘load’ fails you still get valid image data (an image filled with one color).

That two second scribble is my second art ever, the first being me slightly earlier today. It's addictive how nice fingerpainting on a tablet with it is.

If you just download a release from github (ugh) and ./run-medley you can do the two lines I do in the two minute video and drawing-ahoy.
We'll get AI to output bitmasks later. Total AI show
Come on cool mastoartists!

I spent the day learning more about Inkscape; particularly how to convert a bitmap image to a usable svg format. Laser cutters aren't too fond of bitmap images. They're just too pixelated.
Anyway, I had some good success!

…and the “digits” are numbers as well (bitmaps):
“1” → 147460255
“2” → 487657759
“3” → 1042482734
etc.

Yay, I can now also read binary format (P4 type) *.pbm #Bitmap files up to a 320x240 resolution and display them on the #PropellerVGAGraphicsCard of my #Rc2014. P4 binary format means smaller files (~12K) and quicker reading of bitmap data.
So now i can read and display the following bitmap sizes:
256x192
256x224
320x240
320x240 mode required some additonal bit flagging, but other wise works like a charm!
P.S.: I also rewrote the I/O code for reading the files.
Code will be published soon, stay tuned!

I love to take a break from 3D creation to further develop this graphical 2D style.

221 followers · 279 posts · Server octodon.socialYesterday I was doing bit-manipulation in #Rust and I learned a new trick:
I was trying to shift right an u8 by a value between 1 and 8 bits:
myu8 >> (8 - shift)
At an 8 bits shift, I wanted it the result to be zero (all bits shifted), but that's not how (some) CPUs work; so it's undefined behaviour, and the rust compiler will throw a compile error (if it's a const shift), or panic at runtime in debug mode.
So the trick to work around that is simply... to shift twice ! One time for the first bit, and another for the last (potential 6):
(myu8 >> 1) >> (8 - shift - 1)
And that's how one can do this operation fully branchless.
In the end I didn't use the trick at all because I had misunderstood what I really needed, but it was fun !

> But Coffee, what on earth are #Sixel graphics?
👉 Did you know?
You can display actual #bitmap #images on the actual #console in selected #terminal emulators.
Terminals which support this include #MLTerm, #FootTerminal and #XTerm (after configuration). Support in #GnomeTerminal and other #VTE-based terminals is underway.

quick #bitmap #font editor with #godotengine : several hours of work and voilà (i love this tool)
i think it's a funny & quick way to design a basic font
