Display Text Overlay

Once or twice we have come across images with the following "symptoms":

  • pixel data being all black (0s), or may well be other colors
  • overlay data present

When it's been loaded onto DicomViewer, you will normally see a black screen with nothing showing. But if you set the following before the image is being displayed:

DicomImage.OverlayVisible(0)= True

You should be able to see the text labels embedded in the overlay data. See the following sample picture.

Check Presentation_states for more information about storing Displaying Settings (Annotations, windowing, scrolling, zooming, flip/rotate, etc.)
