MinMaxArea Property

Runtime only

Applies To

Vision Objects: Blob

Description

Defines the lower and upper Area limits for the Blob object. For a Blob to be found it must have an Area
result greater than the MinArea property and less than the MaxArea property. (MinMaxArea property was
added to allow easy manipulation of both the MinArea and MaxArea Properties from one function call in
the SPEL

language.)

Usage

VGet Sequence.Object.MinMaxArea, minVar, maxVar

VSet Sequence.Object.MinMaxArea, minVar, maxVar

Sequence Name of a sequence or string variable containing a sequence name.

Object

Name of an object or string variable containing an object name. The object must exist in the
specified sequence.

minVar

Long variable containing the minimum area to get from or set to the MinArea property

maxVar

Long variable containing the maximum area to get from or set to the MaxArea property

Values

For details, refer to MaxArea Property or MinArea Property.

Remarks

The purpose of the MinMaxArea property is to provide a single function call from the SPEL

language to

allow the setting of both the MinArea and MaxArea Properties.

Do no set the MinMaxArea setting too large. If the range is too large, it may result in false detection.
