What is an Overlay? 
 
 
An overlay is something like a transparent sheet that is placed on top of a photographed image. 
Text, count markers, pen drawings, measurement lines, or superimposed images can be written 
on the overlay. The contents written to the overlay can be saved or printed along with the 
image. 
 
Basic method of overlay operation 
All pen drawings, text input, etc., for an image are written onto a single overlay sheet. 
 
Follow the sequence shown below to create an overlay. 
 
Choose the function 
 
Draw or enter text 
↓→
To redo, clear before redrawing 
Paste 
 
While you are drawing, the overlay is simply held in temporary storage, so its layout will not be 
fixed as valid data unless you paste it to the image. If you click 
  to return without pasting, 
the content you’ve drawn will be lost. 
Once the overlay is fixed, you can choose to display or hide it by using  Overlay ON/OFF . 
Displaying or hiding the overlay 
  Overlay ON    displays the overlay on top of the screen. 
  Overlay OFF    hides the overlay from the screen. 
Even while    Overlay OFF , if you press any icon to draw on the overlay, e.g.,    Pen    or   
  Text , the overlay will automatically reappear.   
Erasing the overlay 
Press    Clear All , and    Y/N    will appear asking you to confirm whether or not to erase. 
Press    Y    if you want to erase or    N    if you do not.   
You cannot partially erase an overlay. All pen drawings, count markers, text, 
measurement lines and superimposed objects will be erased. Crosslines and scales, 
however, will not disappear. 
Saving or printing the overlay 
If you save or print an image while an overlay on it is being displayed, the overlay image 
is written over the photographed image when it is saved or printed.   
In this case, the photographed image and the overlay are integrated into a single image 
when saved, so you cannot erase the overlay from the saved image.   
If the overlay is hidden while you save or print, only the photographed image is saved or 
printed. 
 
•  Some text may be dropped when saving an overlay over an image if you save at the 
minimum file size. 
Furthermore, if the image is saved in JPEG format, we recommend selecting a low 
compression rate such as Fine or Normal. 
•  For details, refer to “1.4.2 Image File Settings-File Settings” in Chapter VI.
