C#实现显示图像的动态效果.doc

.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)tryint 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：private void button1_Click(object sender, EventArgs e)tryint 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：private void button1_Click(object sender, EventArgs e)tryint 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(block0,System.Drawing.Imaging.PixelFormat.DontCare),MyBitmap.Clone(block1,System.Drawing.Imaging.PixelFormat.DontCare),MyBitmap.Clone(block2,System.Drawing.Imaging.PixelFormat.DontCare),MyBitmap.Clone(block3,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(MyBitmapBlack0, 0, 0);System.Threading.Thread.Sleep(1000);g.DrawImage(MyBitmapBlack1, width / 2, 0);System.Threading.Thread.Sleep(1000);g.DrawImage(MyBitmapBlack3, width / 2, height / 2);System.Threading.Thread.Sleep(1000);g.DrawImage(MyBitmapBlack2, 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)tryGraphics 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.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 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。代码：private void button1_Click(object sender, EventArgs e)/以左右对接方式显示图像tryint 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); /初始为全灰色Bitmap bitmap = new Bitmap(width, height);int x = 0;while (x = width / 2)for (int i = 0; i = height - 1; i+)bitmap.SetPixel(x, i, MyBitmap.GetPixel(x, i);for (int i = 0; i = height - 1; i+)bitmap.SetPixel(width - x - 1, i,MyBitmap.GetPixel(width - x - 1, i);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);七、以左右反转的方式显示图像原理：计算图像位置和高度后以宽度的一半为轴进行对换左右半边的图像。代码：private void button1_Click(object sender, EventArgs e)/以左右反转方式显示图像tryint 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); /初始为全灰色for (int j = -height / 2; j = height / 2; j+)g.Clear(Color.Gray); /初始为全灰色int i = Convert.ToInt32(j * (Convert.ToSingle(width) / Convert.ToSingle(height);Rectangle DestRect = new Rectangle(width / 2 - i, 0, 2 * i, height);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);八、以从上向下拉伸的方式显示图像原理：将图像的宽度不变每次显示图像的一部分, 直到将图片完全显示。代码：private void button1_Click(object sender, EventArgs e)/以从上向下拉伸方式显示图像tryint 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); /初始为全灰色for (int y = 1; y = height; y+)Bitmap bitmap=MyBitmap.Clone (new Rectangle(0,0,width ,y),System.Drawing .Imaging.PixelFormat .Format24bppRgb );g.DrawImage (bitmap,0,0);System.Threading.Thread.Sleep(10);catch (Exception ex)MessageBox.Show(ex.Message, 信息提示);九、以从左向右拉伸的方式显示图像原理：将图像的高度不变每次显示图像的一部分, 直到将图片完全显示。代码：private void button1_Click(object sender, EventArgs e)/以从左向右拉伸方式显示图像tryint width = this.MyBitmap.Width;
