说明:
由于是以动画方式显示图像,这里没办法直接贴静态截图,因此决定给大家代码开源,将所有的可运行代码附在案例后面,由于所有的动画处理图像的对象放在都pictureBox控件中,同时定义的类都大同小异,因此这里先把下面案例中要用到的所有类及装载图像的代码给大家,运行时用这里的代码加下面任意一个实例的代码即可运行程序!
- private Bitmap SourceBitmap;
- private Bitmap MyBitmap;
- private void button2_Click(object sender, EventArgs e)
- {
- //打开图像文件
- OpenFileDialog openFileDialog = new OpenFileDialog();
- openFileDialog.Filter = "图像文件(JPeg, Gif, Bmp, etc.)
- |*.jpg;*.jpeg;*.gif;*.bmp;*.tif; *.tiff; *.png|
- JPeg 图像文件(*.jpg;*.jpeg)
- |*.jpg;*.jpeg |GIF 图像文件(*.gif)|*.gif |BMP图像文件(*.bmp)|*.bmp
- |Tiff图像文件(*.tif;*.tiff)|*.tif;*.tiff|Png图像
- 文件(*.png)| *.png |所有文件(*.*)|*.*";
- if (openFileDialog.ShowDialog() == DialogResult.OK)
- {
- //得到原始大小的图像
- SourceBitmap = new Bitmap(openFileDialog.FileName);
- //得到缩放后的图像
- MyBitmap = new Bitmap(SourceBitmap, this.pictureBox1.Width, this
- .pictureBox1.Height);
- this.pictureBox1.Image = MyBitmap;
- }
- }
复制代码 一、以上下反转的方式显示图像.
原理:计算图像位置和高度后以高度的一半为轴进行对换上下半边的图像。
代码
- private void button1_Click(object sender, EventArgs e)
- {
- try
- {
- int width = this.MyBitmap.Width; //图像宽度
- int height = this.MyBitmap.Height; //图像高度
- Graphics g = this.panel1.CreateGraphics();
- g.Clear(Color.Gray);
- for (int i = -width / 2; i <= width / 2; i++)
- {
- g.Clear(Color.Gray);
- int j = Convert.ToInt32(i * (Convert.ToSingle(height) / Convert.ToSingle(width)));
- Rectangle DestRect = new Rectangle(0, height / 2 -j, width, 2 * j);
- Rectangle SrcRect = new Rectangle(0, 0, MyBitmap.Width, MyBitmap.Height);
- g.DrawImage(MyBitmap, DestRect, SrcRect, GraphicsUnit.Pixel);
- System.Threading.Thread.Sleep(10);
- }
- }
- catch (Exception ex)
- {
- MessageBox.Show(ex.Message, "信息提示");
- }
- }
复制代码
二、以上下对接的方式显示图像
原理:首先将图像分为上下两部分, 然后分别显示。
代码:- private void button1_Click(object sender, EventArgs e)
- {
- try
- {
- int width = this.pictureBox1.Width; //图像宽度
- int height = this.pictureBox1.Height; //图像高度
- Graphics g = this.panel1.CreateGraphics();
- g.Clear(Color.Gray);
- Bitmap bitmap = new Bitmap(width, height);
- int x = 0;
- while (x <= height / 2)
- {
- for (int i = 0; i <= width - 1; i++)
- {
- bitmap.SetPixel(i, x, MyBitmap.GetPixel(i, x));
- }
- for (int i = 0; i <= width - 1; i++)
- {
- bitmap.SetPixel(i, height - x - 1, MyBitmap.GetPixel(i, height - x - 1));
- }
- x++;
- this.panel1.Refresh();
- g.DrawImage (bitmap,0,0);
- System.Threading.Thread.Sleep(10);
- }
- }
- catch (Exception ex)
- {
- MessageBox.Show(ex.Message, "信息提示");
- }
- }
复制代码
三、以四周扩散的方式显示图像
原理:首先设置图像显示的位置, 然后按高度和宽度的比例循环输出, 直到高度和宽度为原始大小。
代码:
- private void button1_Click(object sender, EventArgs e)
- {
- try
- {
- int width = this.MyBitmap.Width; //图像宽度
- int height = this.MyBitmap.Height; //图像高度
- //取得Graphics对象
- Graphics g = this.panel1.CreateGraphics();
- g.Clear(Color.Gray); //初始为全灰色
- for (int i = 0; i <= width / 2; i++)
- {
- int j = Convert.ToInt32 (i*(Convert.ToSingle(height) / Convert.ToSingle(width)));
- Rectangle DestRect = new Rectangle(width / 2 - i, height/2-j, 2 * i, 2*j);
- Rectangle SrcRect = new Rectangle(0, 0, MyBitmap.Width, MyBitmap.Height);
- g.DrawImage(MyBitmap, DestRect, SrcRect, GraphicsUnit.Pixel);
- System.Threading.Thread.Sleep(10);
- }
- }
- catch (Exception ex)
- {
- MessageBox.Show(ex.Message, "信息提示");
- }
- }
复制代码 四、以分块效果显示图像
原理:首先将图分为几块, 再使用 Bitmap 类的 Clone方法从原图指定的块中复制图像,
最后将这些块依次显示出来便可。
代码:
- private void button1_Click(object sender, EventArgs e)
- {
- Graphics g = this.panel1.CreateGraphics();
- g.Clear(Color.White);
- int width = MyBitmap.Width;
- int height = MyBitmap.Height;
- //定义将图片切分成四个部分的区域
- RectangleF[] block ={
- new RectangleF(0,0,width/2,height/2), new RectangleF(width/2,0,width/2,height/2),
- new RectangleF(0,height/2,width/2,height/2),
- new RectangleF(width/2,height/2,width/2,height/2)};
- //分别克隆图片的四个部分
- Bitmap[] MyBitmapBlack ={
- MyBitmap.Clone(block[0],System.Drawing.Imaging.PixelFormat.DontCare),
- MyBitmap.Clone(block[1],System.Drawing.Imaging.PixelFormat.DontCare),
- MyBitmap.Clone(block[2],System.Drawing.Imaging.PixelFormat.DontCare),
- MyBitmap.Clone(block[3],System.Drawing.Imaging.PixelFormat.DontCare)};
- //绘制图片的四个部分,各部分绘制时间间隔为0.5秒
- g.DrawImage(MyBitmapBlack[0], 0, 0);
- System.Threading.Thread.Sleep(1000);
- g.DrawImage(MyBitmapBlack[1], width / 2, 0);
- System.Threading.Thread.Sleep(1000);
- g.DrawImage(MyBitmapBlack[3], width / 2, height / 2);
- System.Threading.Thread.Sleep(1000);
- g.DrawImage(MyBitmapBlack[2], 0, height / 2);
- }
复制代码 五、以淡入淡出效果显示图像

代码:
- private void button1_Click(object sender, EventArgs e)
- {
- try
- {
- Graphics g = this.panel1.CreateGraphics();
- g.Clear(Color.Gray);
- int width = MyBitmap.Width;
- int height = MyBitmap.Height;
- ImageAttributes attributes = new ImageAttributes();
- ColorMatrix matrix = new ColorMatrix();
- //创建淡入颜色矩阵

- matrix.Matrix33 = (float)1.0;
- matrix.Matrix44 = (float)1.0;
- //从1到0进行修改色彩变换矩阵主对角线上的数值
- //依次减少每种色彩分量
- Single count = (float)1.0;
- while (count > 0.0)
- {
- matrix.Matrix00 = (float)count;
- matrix.Matrix11 = (float)count;
- matrix.Matrix22 = (float)count;
- matrix.Matrix33 = (float)count;
- attributes.SetColorMatrix(matrix, ColorMatrixFlag.Default, ColorAdjustType.Bitmap);
