宋体;">在前九章，我们主要是介绍一些数字图象处理的基本原理和算法，很多细节和优化的算法都没有提，所以程序的通用性和效率并不理想。其实有很多优秀的图象处理编程工具，功能强大，速度很快。在实际的编程中，可以调用它们提供的功能来满足我们自己的需求，提高了编程效率和代码的正确性。</span></p><p style="LINE-HEIGHT: 18pt;"><span style="FONT-FAMILY: 宋体;">在这一章里，将介绍图象处理编程工具</span><span lang="EN-US">LeadTools(OCX)</span><span style="FONT-FAMILY: 宋体;">。给出的例程中要用到</span><span lang="EN-US">Visual C++(</span><span style="FONT-FAMILY:

lang="EN-US">LeadTools(OCX)</span><span style="FONT-FAMILY: 宋体;">是</span><span lang="EN-US">Lead Technologies</span><span style="FONT-FAMILY: 宋体;">公司出品的一款功能强大的图象处理编程工具，目前的最新版本是</span><span lang="EN-US">Lead8.0(1997.7.25)</span><span style="FONT-FAMILY: 宋体;">。</span><span lang="EN-US">LeadTools</span><span style="FONT-FAMILY: 宋体;">实质上是一个</span><span lang="EN-US">OCX</span><span style="FONT-FAMILY: 宋体;">控件。先来说说什么是</span><span lang="EN-US">OCX</span><span style="FONT-FAMILY: 宋体;">控件？</span></p><p style="LINE-HEIGHT: 18pt;"><span style="FONT-FAMILY: 宋体;">如果你用过</span><span lang="EN-US">Visual Basic</span><span style="FONT-FAMILY: 宋体;">或者</span><span lang="EN-US">Delphi</span><span style="FONT-FAMILY: 宋体;">一类的可视化编程工具，那么对控件这个概念一定不会陌生，就是那些工具条上的小按钮，如</span><span lang="EN-US">EditBox</span><span style="FONT-FAMILY: 宋体;">，</span><span lang="EN-US">Grid</span><span style="FONT-FAMILY: 宋体;">，</span><span lang="EN-US">ImageBox</span><span style="FONT-FAMILY: 宋体;">，</span><span lang="EN-US">Timer</span><span style="FONT-FAMILY: 宋体;">等等。每个控件都有自己的事件</span><span lang="EN-US">(</span><span style="FONT-FAMILY: 宋体;">事件</span><span lang="EN-US">) </span><span style="FONT-FAMILY: 宋体;">、方法</span><span lang="EN-US">(</span><span style="FONT-FAMILY: 宋体;">方法</span><span lang="EN-US">)</span><span style="FONT-FAMILY: 宋体;">和属性</span><span lang="EN-US">(</span><span style="FONT-FAMILY: 宋体;">属性</span><span lang="EN-US">)</span><span style="FONT-FAMILY: 宋体;">。使用了控件的编程非常容易。首先，在程序的设计阶段可以设置一些属性，如大小，位置，标题</span><span lang="EN-US">(caption)</span><span style="FONT-FAMILY: 宋体;">等等；在程序运行阶段，可以更改这些属性，还可以针对不同的事件，调用不同的方法来实现对该控件的控制。控件就好象一块块的积木，程序要做的事只是将这些积木搭起来。控件的最大好处是可以重复使用，甚至可以在不同的编程语言之间使用，例如你可以在</span><span lang="EN-US">VB</span><span style="FONT-FAMILY: 宋体;">中嵌入用</span><span lang="EN-US">VC</span><span style="FONT-FAMILY: 宋体;">开发的控件。</span></p><p style="LINE-HEIGHT: 18pt;"><span style="FONT-FAMILY: 宋体;">控件的本质是微软公司的对象链接和嵌入</span><span lang="EN-US">(OLE)</span><span style="FONT-FAMILY: 宋体;">标准。由于它充分利用了面向对象的优点，使得程序效率得到了很大的提高，从而得到了广泛的应用。国外有很多公司就是专门制作各种各样控件的。控件的最早形式是以</span><span lang="EN-US">.VBX</span><span style="FONT-FAMILY: 宋体;">的格式出现的，后来变成了</span><span lang="EN-US">.OCX</span><span style="FONT-FAMILY: 宋体;">。由于</span><span lang="EN-US">Internet</span><span style="FONT-FAMILY: 宋体;">的广泛流行，微软公司推出了</span><span lang="EN-US">ActiveX</span><span style="FONT-FAMILY: 宋体;">技术，就是从</span><span lang="EN-US">OLE</span><span style="FONT-FAMILY: 宋体;">发展起来的，加入了</span><span lang="EN-US">WWW</span><span style="FONT-FAMILY: 宋体;">上的功能。所以目前最流行的是</span><span lang="EN-US">ActiveX</span><span style="FONT-FAMILY: 宋体;">控件。</span></p><p style="LINE-HEIGHT: 18pt;"><span style="FONT-FAMILY: 宋体;">介绍完了</span><span lang="EN-US">OCX</span><span style="FONT-FAMILY: 宋体;">控件的概念，下面我们以</span><span lang="EN-US">Lead Version5.1</span><span

lang="EN-US">Windows3.x</span><span style="FONT-FAMILY: 宋体;">的时代，由于</span><span lang="EN-US">Microsoft</span><span style="FONT-FAMILY: 宋体;">提供的</span><span lang="EN-US">Windows API</span><span style="FONT-FAMILY: 宋体;">不能对硬件直接操作，使得</span><span lang="EN-US">Windows3.x</span><span style="FONT-FAMILY: 宋体;">下的游戏不仅效果差，而且运行速度极慢。而</span><span lang="EN-US">DOS4GW</span><span style="FONT-FAMILY:

lang="EN-US">Windows95</span><span style="FONT-FAMILY: 宋体;">平台，《仙剑奇侠传》出了</span><span lang="EN-US">Win95</span><span style="FONT-FAMILY: 宋体;">版本，</span><span lang="EN-US">Red Alert, Diablo</span><span

lang="EN-US">.DirectDraw</span><span style="FONT-FAMILY: 宋体;">的开发者提供了共同的接口。</span></p><p style="LINE-HEIGHT: 18pt;"><span style="FONT-FAMILY: 宋体;">然而，</span><span lang="EN-US">DirectDraw</span><span style="FONT-FAMILY: 宋体;">并不只限于利用显示适配器的硬件功能。如果你的程序指定了某一种特定的显示适配器，例如</span><span lang="EN-US">XXXX hardware blitter</span><span style="FONT-FAMILY: 宋体;">，但用户并没有该硬件，程序就会使用</span><span lang="EN-US">DirectDraw</span><span style="FONT-FAMILY: 宋体;">的硬件仿真层</span><span lang="EN-US">(HEL)</span><span style="FONT-FAMILY: 宋体;">。在这种情况下，</span><span lang="EN-US">DirectDraw</span><span style="FONT-FAMILY: 宋体;">利用内建的硬件仿真来仿真缺少的硬件。</span></p><p style="LINE-HEIGHT: 18pt;"><span style="FONT-FAMILY: 宋体;">下图一说明了</span><span lang="EN-US">DirectDraw</span><span style="FONT-FAMILY:
