Appendix A. Integrating with Pygame

This appendix shows how to set up the Pygame library and how to use Pygame for window management in an OpenCV application. Also, the appendix gives an overview of Pygame's other functionality and some resources for learning Pygame.

All the finished code for this chapter can be downloaded from my website: http://nummist.com/opencv/3923_06.zip.

Installing Pygame

Let's assume that we already have Python set up according to one of the approaches described in Chapter 1, Setting up OpenCV. Depending on our existing setup, we can install Pygame in one of the following ways:

• Windows with 32-bit Python: Download and install Pygame 1.9.1 from http://pygame.org/ftp/pygame-1.9.1.win32-py2.7.msi.
• Windows with 64-bit Python: Download and install Pygame 1.9.2 preview from http://www.lfd.uci.edu/~gohlke/pythonlibs/2k2kdosm/pygame-1.9.2pre.win-amd64-py2.7.exe.
• Mac with Macports: Open Terminal and run the following command:

  $ sudo port install py27-game
  

• Mac with Homebrew: Open Terminal and run the following commands to install Pygame's dependencies and, then, Pygame itself:

  $ brew install sdl sdl_image sdl_mixer sdl_ttf smpeg portmidi
  $ /usr/local/share/python/pip install \
  > hg+http://bitbucket.org/pygame/pygame
  

• Ubuntu and its derivatives: Open Terminal and run the following command:

  $ sudo apt-get install python-pygame
  

• Other Unix-like systems: Pygame is available in the standard repositories of many systems. Typical package names include pygame, pygame27, py-game, py27-game, python-pygame, and python27-pygame.

Now, Pygame should be ready for use.
