说明：  本书专门讲述了GDI+编程中与开发自定义控件相关的功能，重点放在Windows Forms自定义控件的创建上，同时也讨论了ASP.NET服务器控件的创建问题。全书共分为4个部分：第1部分是对GDI+的用途和结构的概述，第2部分结合代码实例讲述了GDI+编程的具体细节，如绘图表面、坐标系、钢笔和笔刷、文本和字体、图像和图像操作、路径和区域、变换的处理和打印等。其中涉及了GDI+在自定义控件中的应用最相关的所有的类、方法、属性和事件。第3部分集中讲解了自定义控件的设计和开发，包括自定义控件的定义、特征，控件与VS.NET的集成，在控件中如何实现滚动等。第4部分讲述了GDI+功能在Web应用程序中的使用。如在Internet上提供了GDI+图像、创建ASP.NET服务器控件使用GDI+创建Web服务等知识。
(book devoted to the GDI Programming and Development Uncertainty related to the function, Windows Forms focus on the creation of Uncertainty, also discussed the ASP.NET server controls to create problems. The book is divided into four parts : Part 1 is to use the GDI and structural overview Part 2 with code examples GDI programming on the specific details, such as mapping the surface coordinates, pen and brush, text and fonts, graphics and images operation, and regional trails, transform processing and printing. Involved in the GDI Uncertainty of the most relevant of all types, methods, properties and events. Part 3 of Uncertainty focusing on the design and development, including Uncertainty of the definitions, characteristics, VS.NET controls and the integration of the controls on how to a)
