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 – generating the UI code


PyQt4 comes with an application called QT Designer. It is a GUI designer for QT-based applications and provides a quick way to develop a graphical user interface containing some basic widgets. With this, let's see how the Thumbnail Maker dialog looks in QT Designer and then run a command to generate Python source code from the .ui file.

  1. Download the thumbnailMaker.ui file from the Packt website.

  2. Start the QT Designer application that comes with PyQt4 installation.

  3. Open the file thumbnailMaker.ui in QT Designer. Notice the red-colored borders around the UI elements in the dialog. These borders indicate a 'layout' in which the widgets are arranged. Without a layout in place, the UI elements may appear distorted when you run the application and, for instance, resize the dialog. Three types of QLayouts are used, namely Horizontal, Vertical, and Grid layout.

  4. You can add new UI elements, such as a QCheckbox or a QLabel, by dragging and dropping it from the...
