自制完全仿QQ截图工具抢鲜版,免费下载试用

    公司里不知道搞了网络什么限制,我这个机器自古以来上午都登不上腾讯QQ客户端,每次都是上午用WebQQ,中午吃完饭回来才能登客户端。WebQQ用起来慢,而且卡不说,有时候截个图都没有客户端来的便捷。从网上虽然下载了一些截图软件,用起来都不大方便,摸索着自己从网上找了些关于C#截图方面的核心代码(fromhttp://blog.csdn.net/crystal_lz/article/details/8274277),打造了一款属于自己的Winform截图工具。

 

点此下载

    自己做的这款截图工具自我感觉用起来挺好的,大概介绍下使用方法,抓图的过程和其他的一样,抓完图后,双击左键复制到粘贴板,也可以在菜单里面操作,按ESC退出当前截图。

    先上个主界面和截图界面如下(截图软件就这么简单,自己闲来没事,在winform上模仿了个百度搜索,虽然画蛇添足,放上去后感觉给界面还添加了点灵气……):

 

下面分享下核心代码:

  1. 左键按下开始绘图代码
     1         /// <summary>
     2         /// 按下左键开始绘制
     3         /// </summary>
     4         private void imageProcessBox1_MouseDown(object sender, MouseEventArgs e) {
     5             if (imageProcessBox1.Cursor != Cursors.SizeAll &&
     6                 imageProcessBox1.Cursor != Cursors.Default)
     7                 panel1.Visible = false;         //表示改变选取大小 隐藏工具条
     8             //若果在选取类点击 并且有选择工具
     9             if (e.Button == MouseButtons.Left && imageProcessBox1.IsDrawed && HaveSelectedToolButton()) {
    10                 if (imageProcessBox1.SelectedRectangle.Contains(e.Location)) {
    11                     m_ptOriginal = e.Location;
    12                     if (tBtn_Text.IsSelected) {         //如果选择的是绘制文本 弹出文本框
    13                         textBox1.Location = e.Location;
    14                         textBox1.Visible = true;
    15                         textBox1.Focus();
    16                         return;
    17                     }
    18                     m_isStartDraw = true;
    19                     Cursor.Clip = imageProcessBox1.SelectedRectangle;
    20                 }
    21             }
    22         }

     

  2. 移动鼠标开始截图代码
     1         /// <summary>
     2         /// 移动鼠标获取截图区域
     3         /// </summary>
     4         private void imageProcessBox1_MouseMove(object sender, MouseEventArgs e) {
     5             m_ptCurrent = e.Location;
     6             //根据是否选择有工具决定 鼠标指针样式
     7             if (imageProcessBox1.SelectedRectangle.Contains(e.Location) && HaveSelectedToolButton() && imageProcessBox1.IsDrawed)
     8                 this.Cursor = Cursors.Cross;
     9             else if (!imageProcessBox1.SelectedRectangle.Contains(e.Location))
    10                 this.Cursor = Cursors.Default;
    11 
    12             if (imageProcessBox1.IsStartDraw && panel1.Visible)   //在重置选取的时候 重置工具条位置(成立于移动选取的时候)
    13                 this.SetToolBarLocation();
    14 
    15             if (m_isStartDraw) {        //如果在区域内点下那么绘制相应图形
    16                 using (Graphics g = Graphics.FromImage(m_bmpLayerShow)) {
    17                     int tempWidth = 1;

  4. 保存图片到硬盘

     3             saveDlg.Filter = "位图(*.bmp)|*.bmp|JPEG(*.jpg)|*.jpg";
     4             saveDlg.FilterIndex = 1;
     5             saveDlg.FileName = "CAPTURE_" + GetTimeString();
     6             if (saveDlg.ShowDialog() == DialogResult.OK) {
     7                 switch (saveDlg.FilterIndex) {
     8                     case 1:
     9                         m_bmpLayerCurrent.Clone(new Rectangle(0, 0, m_bmpLayerCurrent.Width, m_bmpLayerCurrent.Height),
    10                             System.Drawing.Imaging.PixelFormat.Format24bppRgb).Save(saveDlg.FileName,
    11                             System.Drawing.Imaging.ImageFormat.Bmp);
    12                         this.Close();
    13                         break;
    14                     case 2:

    18                         break;
