| 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!
 
 一、以上下反转的方式显示图像.复制代码
  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; 
  } 
  }
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
 
 复制代码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"); 
} 
} 
 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:
 复制代码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。
 代码:
 
 四、以分块效果显示图像复制代码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"); 
} 
} 
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:
 
 五、以淡入淡出效果显示图像复制代码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); 
} 
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:

{ 
matrix.Matrix00 = (float)count;

this.panel1.Refresh(); 
g.DrawImage (bitmap,0,0); 
System.Threading.Thread.Sleep(10); 
} 
} 
catch (Exception ex) 
{ 
MessageBox.Show(ex.Message, "信息提示");

for (int i = 0; i < 255; i++) 
{//由透明变为不透明 
g.FillRectangle(new SolidBrush(Color.FromArgb(i,Color.DarkSlateGray)), this.panel1.ClientRectangle); 
System.Threading.Thread.Sleep(100); 
} 
}

{ 
//以不同的分辨率显示图像 
Graphics g = this.panel1.CreateGraphics(); 
for (int i = 10; i < this.panel1.Height; i += 2) 
{ 
g.Clear(Color.Gray); 
MyBitmap.SetResolution(i, i); 
g.DrawImage(MyBitmap, 0, 0); 
System.Threading.Thread.Sleep(100); 
} 
}

break; 
case 5: 
MyBitmap.RotateFlip(RotateFlipType.Rotate270FlipNone); 
break; 
case 6: 
MyBitmap.RotateFlip(RotateFlipType.Rotate270FlipX); 
break; 
case 7: 
MyBitmap.RotateFlip(RotateFlipType.Rotate270FlipXY); 
break; 
case 8: 
MyBitmap.RotateFlip(RotateFlipType.Rotate270FlipY); 
break; 
case 9: 
MyBitmap.RotateFlip(RotateFlipType.Rotate90FlipNone); 
break;

break; 
} 
g.Clear(Color.White); 
g.DrawImage(MyBitmap, 0, 0); 
System.Threading.Thread.Sleep(1000); 
} 
} 
复制代码private void button1_Click(object sender, EventArgs e) 
{ 
//椭圆显示图像 
this.panel1.Refresh(); 
Graphics g = this.panel1.CreateGraphics(); 
TextureBrush MyBrush = new TextureBrush(MyBitmap); 
g.FillEllipse(MyBrush, this.panel1.ClientRectangle); 
}
