Overview of this book

Multimedia applications are used by a range of industries to enhance the visual appeal of a product. This book will teach the reader how to perform multimedia processing using Python. This step-by-step guide gives you hands-on experience for developing exciting multimedia applications using Python. This book will help you to build applications for processing images, creating 2D animations and processing audio and video. Writing applications that work with images, videos, and other sensory effects is great. Not every application gets to make full use of audio/visual effects, but a certain amount of multimedia makes any application a lot more appealing. There are numerous multimedia libraries for which Python bindings are available. These libraries enable working with different kinds of media, such as images, audio, video, games, and so on. This book introduces the reader to the most widely used open source libraries through several exciting, real world projects. Popular multimedia frameworks and libraries such as GStreamer,Pyglet, QT Phonon, and Python Imaging library are used to develop various multimedia applications.

Preface

Time for action – animation using a sequence of images


Let's develop a tool that can create an animation and display it on the screen. This tool will create and display the animation using the given image files. Each of the image files will be displayed as a frame in the animation for a specified amount of time. This is going to be a fun little animation that shows a grandfather clock with a pendulum. We will animate the pendulum oscillations with other things, including making the dial remaining still. This animation has only three image frames; two of them show the pendulum at opposite extremes. These images are sequenced as shown in the next illustration.

Clock image frames to be animated appear in the preceding image.

  1. Download the file ImageSequenceAnimation.py from the Packt website.

  2. The code in this file is presented below.

    1 import pyglet
    2
    3 image_frames = ('images/clock1.png',
    4         'images/clock2.png',
    5         'images/clock3.png')
