실시간 화면 캡쳐 기능을 만들고 있는데 WPF에서 CopyFromScreen을 사용하여 BitmapImage를 이용해 화면 캡처 기능을 만들었는데 실행했을 때 화질 저하가 있습니다. 어떻게 해결할 수 있을까요?
private BitmapImage Capture(System.Drawing.Point mousePoint)
{
Bitmap bitmap = new Bitmap(50, 50, System.Drawing.Imaging.PixelFormat.Format32bppArgb);
using (Graphics g = Graphics.FromImage(bitmap))
{
int currPosXOnCenter = (int)mousePoint.X - 25;
int currPosyOnCenter = (int)mousePoint.Y - 25;
g.CopyFromScreen(currPosXOnCenter <= 0 ? 0 : currPosXOnCenter, currPosyOnCenter <= 0 ? 0 : currPosyOnCenter, 0, 0, bitmap.Size);
//g.CopyFromScreen(0, 0, 0, 0, bitmap.Size);
using (MemoryStream memory = new MemoryStream())
{
bitmap.Save(memory, ImageFormat.Bmp);
memory.Position = 0;
BitmapImage bitmapImage = new BitmapImage();
bitmapImage.BeginInit();
bitmapImage.StreamSource = memory;
bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
bitmapImage.EndInit();
return bitmapImage;
}
}
}
private void timer_Tick(object sender, EventArgs e)
{
this.captureScreen.Source = this.Capture(System.Windows.Forms.Cursor.Position);
}
public MainWindow()
{
InitializeComponent();
DispatcherTimer timer = new DispatcherTimer();
timer.Interval = TimeSpan.FromTicks(1000);
timer.Tick += new EventHandler(timer_Tick);
timer.Start();
}
