4.12 Setting Masking
4.12 Setting Masking
Mask areas can be set for gray scale window checkers.
A mask area is an area within an inspection or extraction area where inspection or
extraction is not performed. Setting a mask area is one way of adapting a checker’s
inspection area or an extractor’s area to a complex shape. Only one mask area can be
set per checker.
Area where inspection is performed
Inspection area: rectangle
Mask area: circle
Mask area coordinates can be set in the range X: –511 to 1022, Y: –479 to 958. It is
therefore possible to set the mask outside the screen area, and as long as it remains
within this range, no error is produced if it is moved outside the screen area by an
adjuster.
(However, if you are setting the mask area and it does not fall within the above range,
it will go back to the setup position.)
A checker that generates an error when moved outside the screen area by an adjuster
when an inspection is performed has its checker pattern displayed at the position where
it was set. The area setting is then made by changing the area from this position. The
checker will be executed from the same position where the area is set from the next time
it is executed.
Since the area setting also applies to the next inspection, it is sometimes the case that
it is not possible to set the checker within the screen area because of the amount of
adjustment. (The setting position cannot be set within the screen.) In this sort of
situation, the “Position is out of image range.” message is displayed. Move the area to
the center of the screen before attempting the shape change again. If the error occurs
when the area is set, the coordinates revert to the coordinates before the change was
made.
