Overview

PonyDraw is an online multiuser WebSockets-based drawing application. The key feature of PonyDraw is support for many layers, just like in any professional drawing application.

PonyDraw is licensed under MIT License, which allows you to do pretty much anything you want to and only requires you to keep original attribution and license text. See LICENSE for more info.

Features

• support for many drawing rooms (creatable by users themselves) with no limit on the amount of users in a room
• support for multiple layers in a room
  • layers protect you work from vandals, while still allowing random people to join and draw together with you
  • layers make your work more convenient
• a chat in every room for communication between users
• keyboard shortcuts
• permanent server-side room & layer storage

Client

PonyDraw client (located in the client directory in this repository) is a HTML+JavaScript application that doesn't require any dynamic content and can be served using any web server software (for example, nginx). PonyDraw client uses WebSockets and <canvas>, so a modern browser is required to use it.

Keyboard shortcuts

• permanent tool choice shortcuts
  • p changes your current tool to the pencil
  • c changes your current tool to the color picker
  • e changes your current tool to the eraser
• temporary tool choice modificators (those only work when your current tool is the pencil)
  • Shift changes your current tool to the color picker
  • Ctrl (Cmd on Mac) changes your current tool to the eraser
• other drawing-related shortcuts
  • [ decreases current line thickness by 1
  • ] increases current line thickness by 1
• UI-related shortcuts

  • w shows/hides tools panel

Server

PonyDraw server (located in the server directory in this repository) is a Python application using Twisted and Autobahn. Python 2.7 compatibility is guaranteed, Python 3 might not work.

Configuration & usage

All server-related configuration should be made in file server/config.py. Most of the variables there should be self-explainatory, and I'm too lazy to describe them here anyway. To launch the server, simply type python ./server/server.py in your command line (you might have to do this as root on some OSs).
