This is an ANSI art editor with a familiar interface, if you've ever used TheDraw. However, unlike TheDraw, this runs on modern systems like Linux and does not require MS-DOS. It also has a few tricks up its sleeve, compared to most modern ANSI editors.
For example, most do 16 colors. Durdraw does 256 colors (using xterm-256color escape codes).
Most use Code Page 437 (IBM-PC) character encoding for extended characters. Durdraw uses Unicode, but can import, convert and export CP437 encoding, so your MS-DOS ANSI art stays in-tact. It still lets you input any Unicode character through a Unicode block browser.
Most need a GUI, but Durdraw runs in a standard Utf-8 terminal (like Xterm, Konsole or iTerm2).
Most that do run in the terminal don't support a mouse or are hard to use. Durdraw is pretty easy to use (similar to TheDraw) and has a suite of mouse tools. Ease of use is subjective, of course.
Most don't do animation. Durdraw does, with custom speed control and frame delays.
Thanks for taking a look!
