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.
