由于是以动画方式显示图像，这里没办法直接贴静态截图，因此决定给园友开源，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;}}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);System.Threading.Thread.Sleep(10);}}catch (Exception ex){MessageBox.Show(ex.Message, "信息提示");}}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");}}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。

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");}}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)};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);}五、以淡入淡出效果显示图像原理：使用ImageAttrributes 类的SetColorMatrix() 方法设置颜色, 调整矩阵实现淡出的效果. 此类还可以对颜色进行校正, 调暗, 调亮和移除等。

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.Matrix00 = (float)0.0;matrix.Matrix01 = (float)0.0;matrix.Matrix02 = (float)0.0;matrix.Matrix03 = (float)0.0;matrix.Matrix04 = (float)0.0;matrix.Matrix10 = (float)0.0;matrix.Matrix11 = (float)0.0;matrix.Matrix12 = (float)0.0;matrix.Matrix13 = (float)0.0;matrix.Matrix14 = (float)0.0;matrix.Matrix20 = (float)0.0;matrix.Matrix21 = (float)0.0;matrix.Matrix22 = (float)0.0;matrix.Matrix23 = (float)0.0;matrix.Matrix24 = (float)0.0;matrix.Matrix30 = (float)0.0;matrix.Matrix31 = (float)0.0;matrix.Matrix32 = (float)0.0;matrix.Matrix33 = (float)0.0;matrix.Matrix34 = (float)0.0;matrix.Matrix40 = (float)0.0;matrix.Matrix44 = (float)0.0;matrix.Matrix33 = (float)1.0;matrix.Matrix44 = (float)1.0;//从0到1进行修改色彩变换矩阵主对角线上的数值//使三种基准色的饱和度渐增Single count = (float)0.0;while (count < 1.0){matrix.Matrix00 = count;matrix.Matrix11 = count;matrix.Matrix22 = count;matrix.Matrix33 = count;attributes.SetColorMatrix(matrix, ColorMatrixFlag.Default, ColorAdjustType.Bitmap);g.DrawImage(MyBitmap, new Rectangle(0, 0, width, height),0, 0, width, height, GraphicsUnit.Pixel, attributes);private void button1_Click(object sender, EventArgs e)System.Threading.Thread.Sleep(200);count = (float)(count + 0.02);}}catch (Exception ex){MessageBox.Show(ex.Message, "信息提示");}}private void button3_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();//创建淡出颜色矩阵matrix.Matrix00 = (float)0.0;matrix.Matrix01 = (float)0.0;matrix.Matrix02 = (float)0.0;matrix.Matrix03 = (float)0.0;matrix.Matrix04 = (float)0.0;matrix.Matrix13 = (float)0.0;matrix.Matrix14 = (float)0.0;matrix.Matrix20 = (float)0.0;matrix.Matrix21 = (float)0.0;matrix.Matrix22 = (float)0.0;matrix.Matrix23 = (float)0.0;matrix.Matrix24 = (float)0.0;matrix.Matrix30 = (float)0.0;matrix.Matrix31 = (float)0.0;matrix.Matrix32 = (float)0.0;matrix.Matrix33 = (float)0.0;matrix.Matrix34 = (float)0.0;matrix.Matrix40 = (float)0.0;matrix.Matrix41 = (float)0.0;matrix.Matrix42 = (float)0.0;matrix.Matrix43 = (float)0.0;matrix.Matrix44 = (float)0.0;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);g.DrawImage(MyBitmap, new Rectangle(0, 0, width, height),0, 0, width, height, GraphicsUnit.Pixel, attributes);System.Threading.Thread.Sleep(20);count = (float)(count - 0.01);}}catch (Exception ex){MessageBox.Show(ex.Message, "信息提示");}}六、以左右对接的方式显示图像原理：首先将图像分为左右两部分, 然后分别显示。
