Convert VisionImage to Standard Format

[cdl3]

I have the following C# code for capturing an image from a frame grabber and then displaying it:

      while (true) {
        try {
          session.Snap(vImage);  // vImage is of type VisionImage
          vImage.WritePngFile("C:\\Captured\\frame.png");
          picture.ImageLocation = "C:\\Captured\\frame.png";  // picture is a PictureBox
        } catch (Exception err) { MessageBox.Showerr.ToString()) ; }

     }

This is not very efficient, as the image needs to be read from disc to display it in a PictureBox. Is there a way to convert VisionImage into a format that PictureBox can understand so I can avoid the extra I/O? Thanks.

Hi cdl3,

You could try convert the image to an array with ImageToArray() or the VI below. 

IMAQ ImageToArray VI

I found a C# example at the bottom of this thread (untested). You will need to determine the pixel type of your converted image. Let us know if this is helpful!
