用C#来实现以动画的方式显示图像 以下文字资料是由(全榜网网www.cha138.com)小编为大家搜集整理后发布的内容，让我们赶快一起来看一下吧！

　　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 button _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 pictureBox Width this pictureBox Height); this pictureBox 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 button _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 panel CreateGraphics(); g Clear(Color Gray); for (int i = width / ; i <= width / ; i++) g Clear(Color Gray); int j = Convert ToInt (i * (Convert ToSingle(height) / Convert ToSingle(width))); Rectangle DestRect = new Rectangle( height / j width * j); Rectangle SrcRect = new Rectangle( MyBitmap Width MyBitmap Height); g DrawImage(MyBitmap DestRect SrcRect GraphicsUnit Pixel); System Threading Thread Sleep( ); 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 button _Click(object sender EventArgs e) try int width = this pictureBox Width; //图像宽度 int height = this pictureBox Height; //图像高度 Graphics g = this panel CreateGraphics(); g Clear(Color Gray); Bitmap bitmap = new Bitmap(width height); int x = ; while (x <= height / ) for (int i = ; i <= width ; i++) bitmap SetPixel(i x MyBitmap GetPixel(i x)); for (int i = ; i <= width ; i++) bitmap SetPixel(i height x MyBitmap GetPixel(i height x )); x++; this panel Refresh(); g DrawImage (bitmap ); System Threading Thread Sleep( ); 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

　　private void button _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 panel CreateGraphics(); g Clear(Color Gray); //初始为全灰色 for (int i = ; i <= width / ; i++) int j = Convert ToInt (i*(Convert ToSingle(height) / Convert ToSingle(width))); Rectangle DestRect = new Rectangle(width / i height/ j * i *j); Rectangle SrcRect = new Rectangle( MyBitmap Width MyBitmap Height); g DrawImage(MyBitmap DestRect SrcRect GraphicsUnit Pixel); System Threading Thread Sleep( ); 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 button _Click(object sender EventArgs e) Graphics g = this panel 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( width/ height/ )

　　new RectangleF(width/ width/ height/ ) new RectangleF( height/ width/ height/ ) new RectangleF(width/ height/ width/ height/ ); //分别克隆图片的四个部分 Bitmap[] MyBitmapBlack = MyBitmap Clone(block[ ] System Drawing Imaging PixelFormat DontCare) MyBitmap Clone(block[ ] System Drawing Imaging PixelFormat DontCare) MyBitmap Clone(block[ ] System Drawing Imaging PixelFormat DontCare) MyBitmap Clone(block[ ] System Drawing Imaging PixelFormat DontCare); //绘制图片的四个部分各部分绘制时间间隔为秒 g DrawImage(MyBitmapBlack[ ] ); System Threading Thread Sleep( ); g DrawImage(MyBitmapBlack[ ] width / ); System Threading Thread Sleep( ); g DrawImage(MyBitmapBlack[ ] width / height / ); System Threading Thread Sleep( ); g DrawImage(MyBitmapBlack[ ] height / );

　　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 button _Click(object sender EventArgs e) try Graphics g = this panel 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 Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; //从到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) ; while (count < ) matrix Matrix = count; matrix Matrix = count; matrix Matrix = count; matrix Matrix = count; attributes SetColorMatrix(matrix ColorMatrixFlag Default ColorAdjustType Bitmap); g DrawImage(MyBitmap new Rectangle( width height) width height GraphicsUnit Pixel attributes); private void button _Click(object sender EventArgs e) System Threading Thread Sleep( ); count = (float)(count + ); catch (Exception ex) MessageBox Show(ex Message 信息提示 ); private void button _Click(object sender EventArgs e) try Graphics g = this panel 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 Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; matrix Matrix = (float) ; //从到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) ; while (count > ) matrix Matrix = (float)count; matrix Matrix = (float)count; matrix Matrix = (float)count; matrix Matrix = (float)count; attributes SetColorMatrix(matrix ColorMatrixFlag Default ColorAdjustType Bitmap); g DrawImage(MyBitmap new Rectangle( width height) width height GraphicsUnit Pixel attributes); System Threading Thread Sleep( ); count = (float)(count ); catch (Exception ex) MessageBox Show(ex Message 信息提示 );

　　六以左右对接的方式显示图像
