carbaseus

An online pipeline for image processing.

*carbaseus (feminine carbasea, neuter carbaseum)* : first/second-declension adjective

1. made of fine linen

Carbaseus is an application designed to be the canvas where you can play and express yourself with a /node graph/ based environment for doing image processing.

As such, it must be accessible, easy to use and exhaustive in its functionality.

Currently, it includes 3 types of nodes/functions:

• The input nodes (entry point for image datas)
• The conversion nodes (transform data from a type to an other)
• The processing nodes (apply a transformation on the datas)

You can plug all these nodes together accordingly with their input/output type, and experiment to discover as it goes the results of the treatments.

Getting started

Testing locally

Make sure you are using the latest version of stable rust by running rustup update.

cargo run --release

On Linux you need to first run:

sudo apt-get install libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libspeechd-dev libxkbcommon-dev libssl-dev

On Fedora Rawhide you need to run:

dnf install clang clang-devel clang-tools-extra speech-dispatcher-devel libxkbcommon-devel pkg-config openssl-devel libxcb-devel

For running the build_web.sh script you also need to install jq and binaryen with your packet manager of choice (or with these github repos releases: jq - binaryen)

Compiling for the web

Make sure you are using the latest version of stable rust by running rustup update.

You can compile your app to WASM and publish it as a web page. For this you need to set up some tools. There are a few simple scripts that help you with this:

./setup_web.sh
./build_web.sh
./start_server.sh
open http://127.0.0.1:8080/

• setup_web.sh installs the tools required to build for web
• build_web.sh compiles your code to wasm and puts it in the docs/ folder (see below)
• start_server.sh starts a local HTTP server so you can test before you publish
• Open http://127.0.0.1:8080/ in a web browser to view

The finished web app is found in the docs/ folder (this is so that you can easily share it with GitHub Pages). It consists of three files:

• index.html: A few lines of HTML, CSS and JS that loads your app.
• your_crate_bg.wasm: What the Rust code compiles to.
• your_crate.js: Auto-generated binding between Rust and JS.
