2、下的圖片以縮略圖的形式進(jìn)行瀏覽，方便用戶進(jìn)行查找圖片，并且在瀏覽過程中刪除一張或者多種圖片。3、 可以以實(shí)際大小或者適合窗體的大小對(duì)單張圖片瀏覽并切換到同目錄中的上一張或者下一張圖片進(jìn)行瀏覽。也可以對(duì)同目錄中的圖片以自動(dòng)播放形式進(jìn)行瀏覽，還可以調(diào)整播放時(shí)間間隔。0第2章 設(shè)計(jì)方案2.1 管理器結(jié)構(gòu)設(shè)計(jì) 通過對(duì)結(jié)構(gòu)的分析，以及考慮到要滿足的功能，將管理器分為如下幾個(gè)模塊。1. 主窗體：用來實(shí)現(xiàn)對(duì)圖片的瀏覽，刪除，導(dǎo)入，保存等功能。2. 目錄窗體：用來創(chuàng)建圖片的管理目錄，整理圖片。3. 導(dǎo)入圖片：用來將圖片導(dǎo)入目錄中，整理到相應(yīng)文件夾。 第3章 設(shè)計(jì)實(shí)現(xiàn)3.1程序的主窗體 1、設(shè)計(jì)程序的主窗體用來
