As well as the response grid, made up of the
response positions on the form, FoD-OMR also has an object grid. When
enabled, the object grid sets the points at which a resized or drawn
object 'snaps' to the grid. We strongly recommend an object grid for
from-Image forms.
Setting up the Object Grid
To set up the object grid, select Object Grid from
the Tools menu.
You can set the precise offset of the origin
(top-left corner) of the object grid and the grid spacing. For
manipulating OMR objects and their frames, set both Align
with OMR Grid and Half
of OMR Grid.
Click the Show grid button to view the object grid (in blue). Click
the Snap to grid button
