A simple pixel art editor.

Minimum System Requirements:

• Linux, Windows 7 or Later (Future plans to support Mac & Mobile)
• Atleast 512MB of Usable RAM
• 64-bit Processor (Future plans to support 32-bit processors in future)
• OpenGL v3.0 or Later

You can download pre-built binaries of the software here (Requires login).

The main aim of this software is to be simple on it's own in terms of code & UX. With functionality to write plugins to add support for various things like File Formats, etc.

Requirements for Windows:

• Windows 7 or Later
• VS Build Tools 2019 or Later With Clang Support (Direct Download)
• BusyBox for Windows (Direct Download)
• Python v3.0+ (Direct Download) (Make sure to select "Add To Path" option)

Requirements for Linux:

• POSIX Compliant Shell

• GCC or Clang (And libomp-dev if using Clang)

  On Debian/Ubuntu (And maybe other distros as well), If you're using LLVM-Clang toolchain then libomp-dev has to be installed as it doesn't come packaged with the toolchain for some reason.

• GLFW3 v3.1 or Later.

• MOLD - Modern Linker

  MOLD is used for speeding up the linking process. It is completely optional & Even unnecessary if you're just building for use. It was able to cut my linking time by a second or two which makes things a bit less annoying.

• Python v3.0+

• Tool Preview - Just have a buffer on which user's action are cleared (by storing dirty from previous user input) & drawn on every user input. When it's time to commit just blit the buffer or blend it?
