title: How to merge 2 RGB images in DM by scripting?
body: <p>I would like to overlay 2 (or more) RGB images in Digital Micrograph by scripting. </p>
  
  <p>Unlike some realimages without color that can be merged by summing the intensity, RGB images should be merged in another way but I have no clue. </p>
  
  <p>Thanks for helping!</p>
