I'm a relative beginner in rust looking to build some kind of pixel colour based cellular automata and I am having difficulties deciding which libraries to use as there are many different graphics libraries and video/image libraries. I would just like to be able to manipulate an array of pixels, possibly display and then write them to a video + a final image. Are there any specific libraries which would be recommended for me to use?
image crate provides a basic pixel array you can read and write, and also saving/loading image files, and resizing (which will be useful to make “chunky” pixels for interactive viewing of the CA).
softbuffer provides a way to put pixels on screen — it's not directly compatible with
image but writing conversions is easy with
std's slice and iterator tools. Also take a look at the libraries that
softbuffer's introduction compares itself with.
Thanks, those libraries seem great. Do you know any libraries I can use for joining the images into a video?
I don't know of an obviously good option. I'm interested in the question myself, but haven't got to really trying things out. Some things from my list:
imagefamily of crates supports writing animated GIFs and PNGs, which might be fine if you want to write out a few CA frames, but aren't very compressed.
- I've been meaning to check out
- There are crates with bindings to ffmpeg, but then you have to deal with depending on a complex C library.
Also, you could write out a GIF or collection of separate images, then use a separate tool (such as command line ffmpeg) to reencode them into a video format.
