Nebula Draw

Nebula Draw is a Terminal User Interface (TUI) drawing application, created by the Nebula Centre Project with moderate collaboration from Shreda5 and licensed under the GPL V3 License. Nebula Draw strives to be a high quality method to create ASCII graphics on low-resource systems.

Installation and Execution Instructions

Note: Nebula Draw currently only supports Linux based operating systems. A macOS version is planned for future release.

Verify the ncurses library is present on your system. Most major Linux distributions come with the library preinstalled.

Installation from Source

Installing from source is the preferred way to install Nebula Draw. Compiling a binary from the source code ensures that it will perform the best on your system and allows you to check the validity of the application.

Note: Verify the gcc compiler is installed on your system. Most major Linux distributions come with it preinstalled.
