2、直翻轉(zhuǎn)，順時(shí)針旋轉(zhuǎn)90度，逆時(shí)針旋轉(zhuǎn)90度，反色，浮雕，黑白，柔化，銳化，灰度化，霧化，馬賽克效果，設(shè)置圖像像素大小。(2) 圖片制作：1) 新建圖像；2) 繪制直線，弧線，曲線，空心矩形，實(shí)心矩形，空心橢圓，實(shí)心橢圓，多邊形，實(shí)心多邊形，文本；3) 線型設(shè)置：實(shí)線，虛線，線條粗細(xì)，線條始止端點(diǎn)的形狀4) 顏色設(shè)置：設(shè)置線或?qū)嵭男螤罨蜃煮w的顏色，包括純色（solidbrush）；漸變色（漸變畫筆）；設(shè)置紋理（陰影畫筆）；設(shè)置填充圖片（紋理畫筆）(3) 保存：對(duì)新建的圖像，保存時(shí)選擇路徑，圖片格式，文件名，然后保存。否則直接保存圖象。(4) 另存為：選擇路徑，圖片格式，文件名，然后保存圖像。(5

3、) 菜單和工具欄：軟件需要有菜單和工具欄快捷按鈕，菜單包括所有功能，工具欄可以設(shè)置最常用的快捷按鈕以上是軟件需要實(shí)現(xiàn)的基本功能，但可以自行新增一些功能和繪制圖形。對(duì)于保存和打開圖片功能，一般可設(shè)置支持BMP，JPG，PNG，GIF，TIFF，ICON格式。實(shí)驗(yàn)步驟：1、前期工作1.1新建Windows應(yīng)用程序項(xiàng)目：wuxiuwen，重命名form1，wxw_Form1.cs。1.2 界面制作1.3 添加主界面form類的數(shù)據(jù)成員 private Bitmap img = null; private string fullname = null;/圖像文件完整路徑 private int tem
