Code and Documents



This example shows how to use an Invoke Node to save front panel controls to a JPEG file.



In LabVIEW, we can use the Get Image Invoke Node to return the image of a front panel object and then we can save it as a JPG file by writing the image data to a JPG file. However, if we want to save multiple control images to one JPG file using this method we need to put these controls in a cluster first and create an Invoke Node from the cluster.



  • LabVIEW 2012 (or compatible)


Steps to Implement or Execute Code

  1. Specify a file path to save the JPG file.
  2. Run the VI.
  3. Click on Save when you want to save the wave graph image.
  4. Check the resulting JPG file by browsing to the location where you saved it.

In this example if we try to save the control after converting it to image the clarity of the control in the image format is missing when you zoom it. Is there alternate method to save the control in pdf / word without converting it to image in order maintain the clarity even when we zoom.
