Python 2.6 Graphics Cookbook

内容简介：
Python is a great object-oriented and interactive programming language that lets you develop graphics, both static and animated, using built-in vector graphics functions that are provided with Python.

Python 2.6 Graphics Cookbook is a collection of straightforward recipes and illustrative screenshots for creating and animating graphic objects using the Python language. This book makes the process of developing graphics interesting and entertaining by working in a graphic workspace without the burden of mastering complicated language definitions and opaque examples.

If you choose to work through all the recipes from the beginning, you will learn to install Python and create basic programs for making lines and shapes using the built-in Tkinter module. The confusing topic of color manipulation is explored in detail using existing Python tools as well as some new tools in the recipes. Next you will learn to manipulate font size, color, and placement of text as placing text exactly where you want on a screen can be tricky because font height, inter-character spacing, and text window dimensions all interfere with each other. Then you will learn how to animate graphics, for example having more than one independent graphic object co-exist and interact using various Python methods.

You will also learn how you can work with raster images, such as converting their formats using the Python Imaging Library. Next you will learn how you can combine vector images with raster images so that you can animate the raster images with ease. You will also walk through a set of recipes with the help of which you can handle and manipulate blocks of raw data that may be hundreds of megabytes in size using datastreams, files, and hard drives. You will also learn how you can use Inkscape to dismantle existing images and use parts of them for your own graphics and Python programs. At the end of the book you will learn how you can create GUIs for different purposes.

A quick reference for creating interesting graphic animations using Python programming

你将学到什么:

Install Python and create basic programs for making lines and shapes
Apply different colors to your graphics using widgets and schemes available with the Tkinter module
Work with raster images and animate them by combining vector images with raster images
Optimize the storage and retrieval of graphics using hard disks, datastreams, and so on
Develop GUIs for different purposes to enhance your interaction with the programs
Move graphic objects smoothly around a screen by adding minimum delay and shift
Explore alternative ways and means of getting graphic shape data into Tkinter programs
Create beautiful patterns by setting any number of pivot points in different directions
Use trajectory traces to examine the history of execution required for animating specific behavior of objects
Approach
This book has recipes that show enthusiastic users how easy graphic programming can be. Simple explanations in plain English are used. The recipes are built up, in each chapter, starting as simply as possible and moving to more complex programs with which you can comfortably create 2D vector graphics and animations. You will learn how to combine both vector and photo images seamlessly!

适合的读者：
If you are looking to create animated graphics to represent real-world scenarios then this book is for you. Teachers, scholars, students, and engineers who know it is possible to make fascinating models and demonstrations but have not found a handbook that pulls it all together in one place will find what they need in this recipe bank.

Basic knowledge of Python programming is required and access to the Web and Google will be useful.
