  • c#制作以动画方式显示的图像

制作者:剑锋冷月 单位:无忧统计网,www.51stat.net
 

  十一将至, 放假前将GDI+最后一部分今天终于完成: 以动画的方式显示图像。希望对 GDI+编程的园友有所帮助。

  PPT 以动画方式显示幻灯片是其一个很重要的特点,相信里边一定有您喜欢的动画方式,今天我就带大家认识几款以动画方式显示幻灯片的制作方法,由于是GDI+编程, 这里以图像代替幻灯片(其实原理是相通的)来演示如何制作以动画方式显示图像。

  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! 同时楼主保证每个案例代码都编译通过, 绝不忽悠!

 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);
 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)
 {
 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:

 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)};
 //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);
 }

 

  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.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 < 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);
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.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");
 }
 }

 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
 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); //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
 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); //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)

 {//以从左向右拉伸方式显示图像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); //初始为全灰色
 for (int x = 1; x <= width; x++)
 {
 Bitmap bitmap=MyBitmap.Clone (new Rectangle
 (0,0,x ,height),
 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");
 }
 }

 

  十. 以任意角度旋转图像

  原理: 主要使用了 Graphics 类提供的 RotateTransform() 方法对图像进行旋转.

  代码:

 private void button1_Click(object sender, EventArgs e)
 {
 //以任意角度旋转显示图像
 Graphics g = this.panel1.CreateGraphics();
 float MyAngle = 0;//旋转的角度
 while (MyAngle < 360)
 {
 TextureBrush MyBrush = new TextureBrush(MyBitmap);
 this.panel1.Refresh();
 MyBrush.RotateTransform(MyAngle);
 g.FillRectangle(MyBrush, 0, 0, this.ClientRectangle.Width, this.ClientRectangle.Height);
 MyAngle += 0.5f;
 System.Threading.Thread.Sleep(50);
 }
 }

  十一. 以椭圆的方式显示图像

  原理: 主要使用了 Graphics 类提供的 FillEllipse() 方法和 TextureBrush() 方法.

  代码:

 private void button1_Click(object sender, EventArgs e)
 {
 //椭圆显示图像

 {
 //以不同的透明度显示图像
 Graphics g = this.panel1.CreateGraphics();
 g.SmoothingMode = SmoothingMode.AntiAlias;
 TextureBrush MyBrush = new TextureBrush(MyBitmap);
 g.FillRectangle(MyBrush, this.panel1.ClientRectangle);
 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);
 }
 }

 

  十三. 以不同分辨率显示图像

  原理: Bitmap 类的 SetResolution 方法

 {
 //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);
 }
 }

  十四. 以不同翻转方式显示图像.

  原理: Bitmap 类的 RotateFip()方法

  代码:

 for (int i = 0; i < 17; i++)
 {
 switch (i)
 {
 case 0:
 MyBitmap.RotateFlip(RotateFlipType.RotateNoneFlipX);
break;
 case 1:
 MyBitmap.RotateFlip(RotateFlipType.Rotate180FlipNone);
 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;
 case 10:
 MyBitmap.RotateFlip(RotateFlipType.Rotate90FlipX);
