4.10 Area Setup and Out − of − Area Range Setting
In the case of images for which the correction angle is 0
°
, there are sections where the
off − screen area is displayed. Areas cannot be set in these sections.
For checkers that generate an error at execution due to correction resulting in the image
moving off the screen, the checker pattern is displayed at the setting position. For the
area settings at such times, changes in the area are done from this position. The same
applies for the next executed checker at the position of the area setting.
In some cases, due to the next execution position, and depending on the amount of
correction, area settings may not be possible, even though they are inside the screen
(cases when the setting position cannot be set inside the screen). In such cases, the
error message: “Position is out of image range.” is displayed.
If the error occurs when you are making area settings, the area coordinates are returned
to their original values.

There are some situations in which an error is not generated when a checker is adjusted
out of the screen area by a position and rotation adjuster. In these situations, the area
setting cannot be made without modification. Move the area to the centre of the screen
before setting the area again.
