說明
由於是以動畫方式顯示圖像這裡沒辦法直接貼靜態截圖因此決定給園友開源將所有的可運行代碼附在案例後面由於所有的動畫處理圖像的對象放在都pictureBox控件中同時定義的類都大同小異因此這裡先把下面案例中要用到的所有類及裝載圖像的代碼給大家運行時用這裡的代碼加下面任意一個實例的代碼即可運行程序！
private Bitmap SourceBitmap;
private Bitmap MyBitmap;
private void button_Click(object sender EventArgs e)
{
//打開圖像文件
OpenFileDialog openFileDialog = new OpenFileDialog();
openFileDialogFilter = 圖像文件(JPeg Gif Bmp etc)
|*jpg;*jpeg;*gif;*bmp;*tif; *tiff; *png|
JPeg 圖像文件(*jpg;*jpeg)
|*jpg;*jpeg |GIF 圖像文件(*gif)|*gif |BMP圖像文件(*bmp)|*bmp
|Tiff圖像文件(*tif;*tiff)|*tif;*tiff|Png圖像
文件(*png)| *png |所有文件(**)|**;
if (openFileDialogShowDialog() == DialogResultOK)
{
//得到原始大小的圖像
SourceBitmap = new Bitmap(openFileDialogFileName);
//得到縮放後的圖像
MyBitmap = new Bitmap(SourceBitmap thispictureBoxWidth this
pictureBoxHeight);
thispictureBoxImage = MyBitmap;
}
}
一以上下反轉的方式顯示圖像
原理計算圖像位置和高度後以高度的一半為軸進行對換上下半邊的圖像
代碼
private void button_Click(object sender EventArgs e)
{
try
{
int width = thisMyBitmapWidth; //圖像寬度
int height = thisMyBitmapHeight; //圖像高度
Graphics g = thispanelCreateGraphics();
gClear(ColorGray);
for (int i = width / ; i <= width / ; i++)
{
gClear(ColorGray);
int j = ConvertToInt(i * (ConvertToSingle(height) / ConvertToS
ingle(width)));
Rectangle DestRect = new Rectangle( height / j width * j);
Rectangle SrcRect = new Rectangle( MyBitmapWidth MyBitmapHeight);
gDrawImage(MyBitmap DestRect SrcRect GraphicsUnitPixel);
SystemThreadingThreadSleep();
}
}
catch (Exception ex)
{
MessageBoxShow(exMessage 信息提示);
}
}
二以上下對接的方式顯示圖像
原理首先將圖像分為上下兩部分 然後分別顯示
代碼
private void button_Click(object sender EventArgs e)
{
try
{
int width = thispictureBoxWidth; //圖像寬度
int height = thispictureBoxHeight; //圖像高度
Graphics g = thispanelCreateGraphics();
gClear(ColorGray);
Bitmap bitmap = new Bitmap(width height);
int x = ;
while (x <= height / )
{
for (int i = ; i <= width ; i++)
{
bitmapSetPixel(i x MyBitmapGetPixel(i x));
}
for (int i = ; i <= width ; i++)
{
bitmapSetPixel(i height x MyBitmapGetPixel(i height x ));
}
x++;
thispanelRefresh();
gDrawImage (bitmap);
SystemThreadingThreadSleep();
}
}
catch (Exception ex)
{
MessageBoxShow(exMessage 信息提示);
}
}
三以四周擴散的方式顯示圖像
原理首先設置圖像顯示的位置 然後按高度和寬度的比例循環輸出 直到高度和寬度為原始大小
代碼
private void button_Click(object sender EventArgs e)
{
try
{
int width = thisMyBitmapWidth; //圖像寬度
int height = thisMyBitmapHeight; //圖像高度
//取得Graphics對象
Graphics g = thispanelCreateGraphics();
gClear(ColorGray); //初始為全灰色
for (int i = ; i <= width / ; i++)
{
int j = ConvertToInt (i*(ConvertToSingle(height) / ConvertToSingle(width)));
Rectangle DestRect = new Rectangle(width / i height/j * i *j);
Rectangle SrcRect = new Rectangle( MyBitmapWidth MyBitmapHeight);
gDrawImage(MyBitmap DestRect SrcRect GraphicsUnitPixel);
SystemThreadingThreadSleep();
}
}
catch (Exception ex)
{
MessageBoxShow(exMessage 信息提示);
}
}
四以分塊效果顯示圖像
原理首先將圖分為幾塊 再使用 Bitmap 類的 Clone方法從原圖指定的塊中復制圖像
最後將這些塊依次顯示出來便可
代碼
private void button_Click(object sender EventArgs e)
{
Graphics g = thispanelCreateGraphics();
gClear(ColorWhite);
int width = MyBitmapWidth;
int height = MyBitmapHeight;
//定義將圖片切分成四個部分的區域
RectangleF[] block ={
new RectangleF(width/height/)
new RectangleF(width/width/height/)
new RectangleF(height/width/height/)
new RectangleF(width/height/width/height/)};
//分別克隆圖片的四個部分
Bitmap[] MyBitmapBlack ={
MyBitmapClone(block[]SystemDrawingImagingPixelFormatDontCare)
MyBitmapClone(block[]SystemDrawingImagingPixelFormatDontCare)
MyBitmapClone(block[]SystemDrawingImagingPixelFormatDontCare)
MyBitmapClone(block[]SystemDrawingImagingPixelFormatDontCare)};
//繪制圖片的四個部分各部分繪制時間間隔為秒
gDrawImage(MyBitmapBlack[] );
SystemThreadingThreadSleep();
gDrawImage(MyBitmapBlack[] width / );
SystemThreadingThreadSleep();
gDrawImage(MyBitmapBlack[] width / height / );
SystemThreadingThreadSleep();
gDrawImage(MyBitmapBlack[] height / );
}

while (count > )
{
matrixMatrix = (float)count;
matrixMatrix = (float)count;
matrixMatrix = (float)count;
matrixMatrix = (float)count;
attributesSetColorMatrix(matrix ColorMatrixFlagDefault ColorAdjustTypeBitmap);
