Hi ochensati,
I ran into the same problem a couple of weeks ago. I try to stay away from the IMAQ drivers so i can access the camera from another forms and use .net controls and not activex controls; I use the directshow drivers for the camera and the camera rate is 30fps.
Basically the code that i have has a callback everytime that a new frame arrives. Then from that function I create a new delegate that will handle the new frame. The delegate calls another function that saves the image to the hard drive and then loads the image into the control (for some reason copying the image to the clipboard and loading it did not work, which would be a lot faster, but ...)
here is the code:
//callback for the new frame:
private delegate void imageHandler(Image image);
void videoSource_NewFrame(object sender, AForge.Video.NewFrameEventArgs eventArgs)
{
try
{
//lock (this)
{
Image b;
b = (Image)eventArgs.Frame.Clone();
this.frameSize = eventArgs.Frame.Size;
Invoke(new imageHandler(this.Form1_imageChanged), b);
}
}
catch (Exception)
{
//throw;
}
}
//function to handle the new image
void Form1_imageChanged(Image image)
{
try
{
//Clipboard.SetImage(image);
//image.Dispose();
//bool copyOk = false;
//this.axCWIMAQVision1.ReadImageFromClipboard(this.axCWIMAQViewer1.Image, ref copyOk, axCWIMAQViewer1.Palette);
image.Save("C:\\temp\\temp.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
image.Dispose();
this.axCWIMAQVision1.ReadImage(this.axCWIMAQViewer1.Image, "C:\\temp\\temp.jpg", axCWIMAQViewer1.Palette);
}
catch (Exception)
{
//throw;
}
}
Hope it helps, let me know if you find a solution to copy it to and from the clipboard.
Regards,
