I am creating a Screen Recording app using Windows media encoder, i Can record the video and save it to a disk,now i need to draw a filled circle around the mouse click area when ever the mouse click event Fire( to high light the area that mouse press event occur), is there a way to do that? any code sample? thank you!!! sorry for not inserting the code here is my code
public void CaptureMoni()
{
string dateTime = DateTime.Now.ToString("yyyy.MM.dd _ HH.mm");
var dir = @"C:\VIDEOS\" + dateTime;
try
{
System.Drawing.Rectangle _screenRectangle = Screen.PrimaryScreen.Bounds;
_screenCaptureJob = new ScreenCaptureJob();
_screenCaptureJob.CaptureRectangle = _screenRectangle;
_screenCaptureJob.ShowFlashingBoundary = true;
_screenCaptureJob.ScreenCaptureVideoProfile.FrameRate = 10;
_screenCaptureJob.CaptureMouseCursor = true;
if (!Directory.Exists(dir))
{
Directory.CreateDirectory(dir);
_screenCaptureJob.OutputScreenCaptureFileName = string.Format(Path.Combine(dir, dateTime + ".wmv"));
}
}
catch (Exception)
{
MessageBox.Show("Screnn Capturing Failed!" );
}
string temPath = (_screenCaptureJob.OutputScreenCaptureFileName.ToString());
// MessageBox.Show(temPath);
}
public ScreenCaptureJob _screenCaptureJob { get; set; }
finally i did what i need Special thanks to PacMani he direct me the right way,
NOTE : this is not a full code which include red circle in the video, this is only for having a red circle and making the transparent form on top of the all the other forms (sorry for the language mistakes)) thank you for the Help @ PacMAni
