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.

Project: Watermark Maker Tool


We have now learned enough image enhancement techniques to take up a simple project applying these techniques. Let's create a simple command line utility, a "Watermark Maker Tool". Although we call it a "Watermark Maker ", it actually provides some more useful features. Using this utility, you can add the date stamp to the image (the date on which the image was enhanced using this tool). It also enables embedding custom text within an image. The tool can be run on the command line using the following syntax:

python WaterMarkMaker.py [options]

Where, the [options] are as follows:

  • --image1: The file path of the main image that provides canvas.

  • --waterMark: The file path of the watermark image (if any).

  • --mark_pos: The coordinates of top-left corner of the watermark image to be embedded. The values should be specified in double quotes, like 100, 50.

  • --text: The text that should appear in the output image.

  • --text_pos: The coordinates of top-left corner of the TEXT to...
