1、課程設(shè)計(jì) 目 錄設(shè)計(jì)目的 - 2總體設(shè)計(jì) - 2模塊設(shè)計(jì) - 3核心代碼 - 7設(shè)計(jì)測試 - 11心得體會(huì) - 15 參考文獻(xiàn) - 16 一 設(shè)計(jì)目的1）掌握.NET基本結(jié)構(gòu)以及C#語言的基本知識(shí)和技能；2）基本掌握面向?qū)ο蟪绦蜷_發(fā)的基本思路和方法；3）掌握GDI+開發(fā)基本知識(shí)；4）利用所學(xué)的基本知識(shí)和技能，進(jìn)行簡單數(shù)據(jù)庫應(yīng)用程序設(shè)計(jì)課程設(shè)計(jì)是我們的主要教學(xué)實(shí)踐環(huán)節(jié),通過課程設(shè)計(jì)我們圍繞基礎(chǔ)課或者專業(yè)課,運(yùn)用學(xué)的知識(shí),結(jié)合實(shí)際應(yīng)用設(shè)計(jì)而進(jìn)行的一次綜合分析設(shè)計(jì)能力的訓(xùn)練. 課程設(shè)計(jì)的宗旨在與培養(yǎng)我們在本課程范圍內(nèi),初步掌握解決實(shí)際應(yīng)用問題時(shí)所應(yīng)具備的查閱資料,綜合運(yùn)用所學(xué)知識(shí)的能力,為畢業(yè)設(shè)計(jì)及

2、今后從事專業(yè)工作打下基礎(chǔ).通過本次課程設(shè)計(jì),能夠鍛煉我們的動(dòng)手能力,使我們能夠很好的鞏固上一個(gè)學(xué)期所學(xué)的知識(shí)內(nèi)容,掌握工程軟件設(shè)計(jì)的基本方法,強(qiáng)化了我們上機(jī)動(dòng)手的能力,通過這次的課程設(shè)計(jì),我們感覺到了以前學(xué)習(xí)的不足,以及在學(xué)習(xí)的過程中遇到的問題,能使我們對(duì)學(xué)過的知識(shí)加深理解,為后續(xù)學(xué)的計(jì)算機(jī)專業(yè)課,打下堅(jiān)實(shí)的基礎(chǔ).在課程設(shè)計(jì)過程中我們感覺到了,團(tuán)體合作的重要性,我們組幾個(gè)人進(jìn)行合作分工,提高了設(shè)計(jì)的效率,充分體現(xiàn)了團(tuán)體精神,為以后出去在社會(huì)上工作時(shí)的合作精神奠定了基礎(chǔ),能夠感覺到合作的重要性.還有在老師的指導(dǎo)下我們我們才能順利的進(jìn)行設(shè)計(jì),感覺到了老師的重要性,有了老師我們設(shè)計(jì)才有了方向目標(biāo).二

3、 總體設(shè)計(jì)簡單繪圖板程序此圖形圖像處理機(jī)具有如下功能：1能由鼠標(biāo)控制繪制直線、矩形、橢圓，并能控制線條的顏色2能改變矩形和橢圓。3能打開和保存為圖形文件。4能打開圖片。5能通過參數(shù)對(duì)圖片進(jìn)行縮放我們做的這個(gè)繪圖板是一個(gè)簡易的類似Windows畫圖工具的簡單繪圖板程序,我們設(shè)計(jì)了主要有菜單欄,狀態(tài)欄等基本元素,能夠?qū)崿F(xiàn)簡單的集合畫圖,也能夠在鼠標(biāo)控制下進(jìn)行手動(dòng)畫圖.通過測試程序能夠順利運(yùn)行. 要求利用C#的編程思想以及組件開發(fā)原理來完成系統(tǒng)的設(shè)計(jì)； 突出C#語言與其它語言不同點(diǎn)（即體現(xiàn)C#的高級(jí)功能，如屬性概念、接口、事件、委托等）體現(xiàn)可視化編程基本東西，如系統(tǒng)帶有菜單、工具欄、狀態(tài)欄以及一些常

4、用的高級(jí)控件。主要流程圖如下：新建矩形直線畫筆時(shí)間簡易繪圖板文件查找關(guān)于打開保存退出工具欄狀態(tài)欄顏色橡皮橢圓選擇工具三 主要模塊菜單欄及狀態(tài)欄 菜單有 文件 ( 新建 打開 保存 退出) 查看 (工具欄 狀態(tài)欄) 關(guān)于一 新建其中新建就是創(chuàng)建子窗體代碼 Form1 pic = new Form1(); Pic.show();/創(chuàng)建一子窗體 然后調(diào)用Show()方法顯示該窗體二 打開 打開是執(zhí)行 muopen_Click事件處理程序.當(dāng)點(diǎn)擊 文件打開 的時(shí)候就會(huì)打開到設(shè)定的目錄下,并顯示要打開的文件類型代碼分析OpenFileDialog openFile1= new OpenFileDialo

5、g();openFile1.InitialDirectory= "c:"openFile1.Filter="Graphics File(*.BMP;*.JPG;*.GIF)|*.BMP;*.JPG;*.GIF|All Files(*.*)|*.*"openFile1.FilterIndex=1;openFile1.RestoreDirectory=true;if(openFile1.ShowDialog()=DialogResult.OK&&openFile1.FileName.Length>0)pictureBox1.Image

6、=Image.FromFile(openFile1.FileName);首先創(chuàng)建打開文件對(duì)話框openfile1 InitialDirectory是文件初始目錄的符串 Filter為文件名篩選器字符串,用于決定打開時(shí)出來的類型, FilterIndex 就是打開時(shí)的索引值,打開時(shí)的類型. RestoreDirectory 表示在關(guān)閉對(duì)話框時(shí)是否還原到當(dāng)前目錄. If判斷是否點(diǎn)擊了打開按pictureBox1.Image =Image.FromFile(openFile1.FileName)是加載選定的文件.三 保存 SaveFileDialog 類表示一個(gè)通用對(duì)話框,創(chuàng)建子類并調(diào)用ShowDi

7、alog方法來顯示對(duì)話框,允許指定用于保存文件選項(xiàng). 通過對(duì)話框能夠?qū)ictureBox1控件中的文件存盤. 代碼分析SaveFileDialog saveFile1= new SaveFileDialog();saveFile1.Filter="GraphicsFile(*.BMP;*.JPG;*.GIF)|*.BMP;*.JPG;*.GIF|AllFiles(*.*)|*.*"saveFile1.ShowDialog();saveFile1.FilterIndex=4; saveFile1.RestoreDirectory=true; saveFile1.Initia

8、lDirectory= "c:" if (saveFile1.FileName!="")this.pictureBox1.Image.Save(saveFile1.FileName,System.Drawing.Imaging.ImageFormat.Bmp);this.Text=saveFile1.FileName;elseMessageBox.Show("必須輸入文件名");同打開一樣首先創(chuàng)建一另存為對(duì)話框 當(dāng)單擊保存的時(shí)候則ShowDialog方法的返回為DialogResult.OK 否則為 DialogResult.Canc

9、el然后再判斷是否保存,調(diào)用pictureBox1控件的SavaFile方法,要指定要保存的文件,并且指定類型!四 退出 當(dāng)單擊退出按鈕的時(shí)候就可以執(zhí)行下列代碼, this.menuItem5.Index = 3;this.menuItem5.Text = "退出"this.menuItem5.Click += new System.EventHandler(this.menuItem5_Click);五 工具欄核心代碼 using System;using System.Drawing;using System.Collections;using System.Compo
