C# 화면 캡쳐 Capture

 

 

1. 비트맵으로

byte[] byteArray;
public void Capture()
{
    System.Drawing.Rectangle rect = Screen.PrimaryScreen.Bounds;
    Bitmap tBitmap = new Bitmap(rect.Width, rect.Height);
    using (Graphics tGraphics = Graphics.FromImage(tBitmap))
    {
        tGraphics.CopyFromScreen(rect.Left, rect.Top, 0, 0, rect.Size);
    }
    byteArray = ImageToByte(tBitmap);
}
 
public static byte[] ImageToByte(System.Drawing.Image img)
{
    ImageConverter converter = new ImageConverter();
    return (byte[])converter.ConvertTo(img, typeof(byte[]));
}

 

 

 

 

2. 이미지로

private void ScreenShotToImage()
{
    var screenSize = new System.Drawing.Size((int)SystemParameters.VirtualScreenWidth, (int)SystemParameters.VirtualScreenHeight);
 
    try
    {
        using (var img = ScreenShot.CaptureImage(System.Drawing.Point.Empty, System.Drawing.Point.Empty, screenSize))
        {
            UpdateImage(img);
        }
        addListItem("Sending to Capture Image for Server");
    }
    catch (Exception ex)
    {
        App.WriteLine(ex.Message);
    }
}
 
 
public class ScreenShot
{
    public static Image CaptureImage(Point SourcePoint, Point DestinationPoint, Size size, int reduceScale = 4)
    {
        using (Bitmap bitmap = new Bitmap(size.Width, size.Height))
        {
            using (Graphics g = Graphics.FromImage(bitmap))
            {
                g.CopyFromScreen(SourcePoint, DestinationPoint, size);
            }
 
            return bitmap.GetThumbnailImage(size.Width / reduceScale, size.Height / reduceScale, null, IntPtr.Zero);
        }
    }
}
