oxipng VS rust

I have had good experiences with https://github.com/shssoichiro/oxipng . Although, I suspect this wouldn't give you nearly enough space savings as jpg.

If you do want the file as a PNG (for transparency and a common format that's well supported), but don't want it so huge, consider something like oxipng. https://github.com/shssoichiro/oxipng

oxipng, pngquant and svgcleaner — optimizing images

I wonder how `pngcrush` compares to `oxipng` (https://github.com/shssoichiro/oxipng).

Personally, I use `oxipng` if I want lossless compression. However, most of the time, I use `pngquant` instead, since it gives significant size reduction even at `99%` (I can't even distinguish between the original and reduced image).

    pngquant --quality=99 --ext=.png --force file.png

Depending on your workflow it might make sense to export PNGs directly from Affinity and then reduce their size with a utility like Oxipng, which uses all your cores to find the best algorithm for each particular image.

Assuming your frames are PNG files, you could use a lossless optimizer like optipng to try if their size can be reduced. I prefer oxipng, which is faster and multithreaded, and seems to have more active development.

Not sure what extensions of images you use, but if they’re PNG you could use oxipng: https://github.com/shssoichiro/oxipng

The esp-template issue might be this one: https://github.com/esp-rs/rust/issues/158. Try with --release or updating to 1.68.0 with espup update. I'll take a look at the log as soon as I can, atm Im on the phone and is not that easy to scroll through :(

Sure. Espressif maintains a fork which adds support for their microcontrollers.

I am trying to make a vaccine passport validation for my country using the ESP32 for my micro controller. I have gotten the std rust library to compile using (esp-rs)[https://github.com/esp-rs/rust], but the actual validation library that I use needs openssl which refuses to compile.

Xtensa. They've got a fork of LLVM that supports it that they're working toward getting upstreamed. The community has a fork of rustc that uses it (and a quickstart crate) while we wait for it to get upstreamed.

It only works if you have an Xtensa compiler which takes hours to compile, here: Rust Xtensa (if you don't have it). The network driver is just a function that sets the name of the driver so the Esp32 does something other that blinking.
