[英]Taking a screenshot of certain section of screen in C#?
我想對屏幕的一部分進行截圖,然后將該信息存儲在圖像數組中。 有沒有辦法修改這個類: http : //pastebin.com/PDPPxmPT這樣它可以讓我截取特定區域的截圖? 例如,如果我想要位圖的x,y像素來源為200,200且x,y目的地為600,700,我將如何進行此操作?
我在這里修改它
編輯:這是代碼
public static Color[,] takeScreenshot(int x=0, int y=0, int width=0, int height = 0)
{
if (width==0)
width = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width;
if (height==0)
height = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height;
Bitmap screenShotBMP = new Bitmap(width,
height, PixelFormat.Format32bppArgb);
Graphics screenShotGraphics = Graphics.FromImage(screenShotBMP);
screenShotGraphics.CopyFromScreen(x,
y, 0, 0, new Size(width,height),
CopyPixelOperation.SourceCopy);
screenShotGraphics.Dispose();
return bitmap2imagearray(screenShotBMP);
}
public static Color[,] bitmap2imagearray(Bitmap b)
{
Color[,] imgArray = new Color[b.Width, b.Height];
for (int y = 0; y < b.Height; y++)
{
for (int x = 0; x < b.Width; x++)
{
imgArray[x, y] = b.GetPixel(x, y);
}
}
return imgArray;
}
不是答案,而是包括來自pastebin的代碼,因為它將來可能會在某個時候消失,並且可能對其他人有用。
public static Color[,] takeScreenshot()
{
Bitmap screenShotBMP = new Bitmap(System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width,
System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height, PixelFormat.Format32bppArgb);
Graphics screenShotGraphics = Graphics.FromImage(screenShotBMP);
screenShotGraphics.CopyFromScreen(System.Windows.Forms.Screen.PrimaryScreen.Bounds.X,
System.Windows.Forms.Screen.PrimaryScreen.Bounds.Y, 0, 0, System.Windows.Forms.Screen.PrimaryScreen.Bounds.Size,
CopyPixelOperation.SourceCopy);
screenShotGraphics.Dispose();
return bitmap2imagearray(screenShotBMP);
}
public static Color[,] bitmap2imagearray(Bitmap b)
{
Color[,] imgArray = new Color[b.Width, b.Height];
for (int y = 0; y < b.Height; y++)
{
for (int x = 0; x < b.Width; x++)
{
imgArray[x, y] = b.GetPixel(x, y);
}
}
return imgArray;
}
