简易图像编辑与制作软件.doc

C#.NET课程设计实验报告班级：计算机1302 姓名：吴秀文 学号：201320100218 题目：简易图像编辑与制作软件的实现目的：(1) 采用C#制作一个简易的图像编辑与制作软件，巩固C#的知识。(2) 培养学生独立完成C#项目的开发经验。任务要求：(1) 图像编辑：1) 打开要编辑的图片，并显示初始图像：包括从菜单的“打开”项，工具栏“打开”按钮和系统打开方式（即在我的电脑里，选中图片文件后，右建打开方式选择本软件打开图片），以及拖放打开方式（即将图片拖动到打开的软件界面，就将该图打开显示）四种打开图片的功能均需实现。2) 显示功能：图像放大，缩小，实际大小3) 图像编辑：水平翻转，垂直翻转，顺时针旋转90度，逆时针旋转90度，反色，浮雕，黑白，柔化，锐化，灰度化，雾化，马赛克效果，设置图像像素大小。(2) 图片制作：1) 新建图像；2) 绘制直线，弧线，曲线，空心矩形，实心矩形，空心椭圆，实心椭圆，多边形，实心多边形，文本；3) 线型设置：实线，虚线，线条粗细，线条始止端点的形状4) 颜色设置：设置线或实心形状或字体的颜色，包括纯色（solidbrush）；渐变色（渐变画笔）；设置纹理（阴影画笔）；设置填充图片（纹理画笔）(3) 保存：对新建的图像，保存时选择路径，图片格式，文件名，然后保存。否则直接保存图象。(4) 另存为：选择路径，图片格式，文件名，然后保存图像。(5) 菜单和工具栏：软件需要有菜单和工具栏快捷按钮，菜单包括所有功能，工具栏可以设置最常用的快捷按钮以上是软件需要实现的基本功能，但可以自行新增一些功能和绘制图形。对于保存和打开图片功能，一般可设置支持BMP，JPG，PNG，GIF，TIFF，ICON格式。实验步骤：1、前期工作1.1新建Windows应用程序项目：wuxiuwen，重命名form1，wxw_Form1.cs。1.2 界面制作1.3 添加主界面form类的数据成员 private Bitmap img = null;
