v0.2.0 alpha

a modern and extensible pixel editor implemented in rust

Download for GNU/Linux
overview.png

rx is an extensible, modern and minimalist pixel editor and animator implemented in rust[0]. It's designed to have as little UI as possible, and instead takes inspiration from vi's[1] modal nature and command mode.

Compared to other pixel editors, rx aims to be smaller yet more configurable and extendable. `rx` takes a different approach when it comes to animation as well, which is done with *strips*.

GOALS

  • * Minimal UI. Clean aesthetics. No clutter.
  • * Everything that should be controlled by the keyboard, is.
  • * Extensible and scriptable with a simple command-based language.
  • * Familiar to anyone with vi(m) knowledge.
  • * Snappy. All commands run in < 16ms.
  • * Optimized for advanced users. vi-like philosophy.
  • * Small, hackable codebase. At most 10 KLOC.
  • * First-class Linux support.
  • * CPU & memory efficient.

FEATURES

  • * Built-in sprite animation support, with live preview.
  • * Work with multiple files simultaneously.
  • * Extensible command system.
  • * Text-based configuration.
  • * HiDPI display support.
  • * Undo/redo support.
  • * Color palette support.
  • * PNG support.
  • * Animated GIF support.
  • * Multi-brush / synchronous editing.
  • * Symmetry brush mode.
  • * Brush filtering a.k.a "pixel-perfect" mode.
  • * Coming soon: Layers.
  • * Coming soon: Visual mode.
  • * Coming soon: Workspaces.

REQUIREMENTS

Linux

On Linux, Vulkan support is required. The drivers can be installed for example with apt install mesa-vulkan-drivers on debian-based systems.

macOS

On macOS, Metal support is required. This usually requires installing Xcode and the Xcode Command Line Tools .

Windows

On Windows, Vulkan support is required.

DOWNLOAD

Disclaimer: this is alpha software, use at your own risk!

On Linux, the simplest way to get rx is to download the AppImage from here:

Then make it executable with eg. chmod +x , rename it to rx and move it somewhere in your PATH .

For macOS and Windows, see the following section.

BUILD FROM SOURCE

You'll need cargo and rust to build rx from source. For more detailed instructions, see the README .

Linux

$ cargo install --git https://github.com/cloudhead/rx --tag v0.2.0 --locked --features vulkan

macOS

$ cargo install --git https://github.com/cloudhead/rx --tag v0.2.0 --locked --features metal

Windows

$ cargo install --git https://github.com/cloudhead/rx --tag v0.2.0 --locked --features vulkan

The default installed palette issweetie16.palette. Other palettes are also availablehere, and you can create your own.

USAGE

After installing, simply run rx from a shell or application launcher. You can then use the :help command to show the current set of key mappings and commands.

Common commands:

:help                    Display help
      :e <path..>              Edit path(s)
      :w                       Write/save view
      :q                       Quit view
      :slice <n>               Slice view into <n> frames
      :source <path>           Source an rx script (eg. a palette)
      :f/resize <w> <h>        Resize frames

CONFIGURATION

Configuring rx involves editing the init.rx script, which is found in a platform-dependent location. On Linux, this is in the XDG config directory, eg. ~/.config/rx/init.rx , while on macOS this is in the ~/Library/Preferences folder. written.

To get the exact location of the config directory, enter :echo config/dir from inside rx .

CONTRIBUTE

The source code is available at github.com/cloudhead/rx . rx is free software .

TROUBLESHOOTING

If something ain't working like it's supposed to, there are various things you can do to debug the problem:

  1. 1. Run rx with verbose logging, by using the -v command-line flag. This will log errors from the underlying libraries that are usually suppressed. You can increase the verbosity further by using -vv .
  2. 2. Try the winit backend, by building rx with eg. --features winit,vulkan .

Otherwise, see the following BUGS section.
