TPicShow is an image slider control with 172 transitional effects in pure Delphi code. PicShow是一组由纯Delphi代码编写的图形控件，支持172种图片切换特效。 The major characteristics of TPicShow are: 控件TPicShow的主要特性为： Image transition can be controlled programmatically 图片过渡效果可编程灵活控制； Image can be stretched or centered in the client area of the control 图片可拉伸或居中显示； Control can show a background image as centered, stretched, or tiled 控件中可显示背景图片，可居中、拉伸或平铺显示。 Transition process can use a separated thread 可在独立线程中处理图片切换。 New transitional effects can be easily implemented and added to the control 易于扩展新的图片切换特效。 TDBPicShow is the data-aware version of TPicShow with ability to load bitmap, jpeg, metafile, and png (Delphi 2009 and later) images from a blob field. 控件TDBPicShow是TPicShow的数据感知版本，该控件可从数据库的blob字段加载bitmap、jpeg、metafile和png（在D2009或更新版本下）格式的图片。
HISTORY 更新情况 Version 4.10 (March 5, 2009) V4.10版本（2009年3月5日） - In threaded mode the component uses multimedia timer instead of a separate thread, which makes having much smoother transitions. Because of that the ThreadPriority is no more present. - 在线程模式下，使用了多媒体定时器（注：时间控制精度较高）替换了独立线程方式，可使图片过渡效果更流畅。因此不再提供线程属性。
