概要

本分步指南介绍了如何在 Windows XP 显示上启用 ClearType 以便使字体清晰。 ClearType 通过使屏幕字体的边缘平滑来增强显示。 ClearType 尤其适用于液晶显示 (LCD) 设备，包括平面屏幕监视器和便携式计算机。

如何

昨天升级sp3，发现C盘空间不够，于是把wdk的文档拷到D盘，最后更新完毕后再拷回去。
结果今天发现很多帮助文档打不开了，提示“无法显示microsoft文档资源管理器，因为指定的帮助集合“ms-help://ms.msdnqtr.v80.chs”无效 ”，包括WDK，MSDN等等，出错信息与该提示类似。

于是修复dexplore，卸载wdk都无效，一怒之下删掉help8这个dexplore所在目录，然后从别人那考过来一个，一切ok！

Using Direct Draw Clippers

Overview

Clippers allow you to restrict which portions of a surface can be blitted to at a particular point of program execution. This is accomplished by specifying one or more rectangles in which blitting can occur, known as a clip list.

Direct Draw Clippers should definitely be used in place of software algorithms that perform clipping, because Direct Draw Clippers will take advantage of video hardwar

Blitting to a Surface Using Direct Draw

Overview

Direct Draw allows you to manipulate surfaces by copying data to it through a block transfer, popularly known as a blit. A block transfer is simply copying one region of memory to another. In the case of Direct Draw, however, both the source and the destination of the blit are Direct Draw surfaces.

Direct Draw allows you to take advantage of video hardware acceleration capabilitie

Direct Draw Surfaces

Overview

A Direct Draw surface is simply a linear block of display memory. Surfaces can be copied, manipulated, and destroyed. This document describes Direct Draw surfaces and how to use them. You should have read Direct Draw Initialization prior to reading this document.

Direct Draw Initialization

Overview

Before you can use Direct Draw to manipulate the screen, you must first perform some initialization. This document describes the necessary and optional steps involved in Direct Draw initialization. See a reference for missing information about parameters, return values, etc.

Initialization Steps

1. (Optional) Enumerate the display devices on the target system by in
