3.2What 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.

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 .
