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 – Watermark Maker Tool


Think about all the methods we would need to accomplish this. The first thing that comes to mind is a function that will process the command-line arguments mentioned earlier. Next, we need to write code that can add a watermark image to the main image. Let's call this addWaterMark(). On similar lines, we will need methods that add text and date stamp to the image. We will call this addText() and addDateStamp() respectively. With this information, we will develop code to make this work. In this project, we will encapsulate this functionality in a class, but it is not necessary. We do so to make this tool extensible for future use.

  1. Download the file WaterMarkMaker.py. This has the code required in this project. Just keep it for further use. Some of the methods will not be discussed in this section. If you encounter difficulties while developing those methods, you can always go back and refer to this file.

  2. Open a new Python source file and declare the following...
