C# 制作以动画的方式显示图像[6]

try

{

int width = thisMyBitmapWidth; //图像宽度

int height = thisMyBitmapHeight; //图像高度

Graphics g = thispanelCreateGraphics();

gClear(ColorGray); //初始为全灰色

Bitmap bitmap = new Bitmap(width height);

int x = ;

while (x <= width / )

{

for (int i = ; i <= height ; i++)

{

bitmapSetPixel(x i MyBitmapGetPixel(x i));

}

for (int i = ; i <= height ; i++)

{

bitmapSetPixel(width x i

MyBitmapGetPixel(width x i));

}

x++;

thispanelRefresh();

gDrawImage (bitmap);

SystemThreadingThreadSleep();

}

}

catch (Exception ex)

{

MessageBoxShow(exMessage 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 button_Click(object sender EventArgs e)

{

//以左右反转方式显示图像

try

{

int width = thisMyBitmapWidth; //图像宽度

int height = thisMyBitmapHeight; //图像高度

Graphics g = thispanelCreateGraphics();

gClear(ColorGray); //初始为全灰色

for (int j = height / ; j <= height / ; j++)

{

gClear(ColorGray); //初始为全灰色

int i = ConvertToInt(j * (ConvertToSingle(width) / ConvertToSingle(height)));

Rectangle DestRect = new Rectangle(width / i * i height);

Rectangle SrcRect = new Rectangle( MyBitmapWidth MyBitmapHeight);

gDrawImage(MyBitmap DestRect SrcRect GraphicsUnitPixel);

SystemThreadingThreadSleep();

}

}

catch (Exception ex)

{

MessageBoxShow(exMessage 信息提示);

}

}
