Extrema Result
Runtime only
Applies To
Vision Objects: Blob, DefectFinder
Description
Returns the blob extrema coordinates.
Usage
VGet Sequence.Object.Extrema [(result)], varMinX, varMaxX, varMinY, varMaxY
- 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.
- varMinX
- Integer variable containing minimum X position of the blob's Extrema.
- varMaxX
- Integer variable containing maximum X position of the blob's Extrema.
- varMinY
- Integer variable containing minimum Y position of the blob's Extrema.
- varMaxY
- Integer variable containing maximum Y position of the blob's Extrema.
- result
- Optional result number. If omitted, the result number is the CurrentResult. Used for objects that return multiple results.
Values
The values returned are always in: pixels and may be from 1 - ImageSize property height.
Remarks
The MinX, MaxX, MinY, and MaxY results together define a blob's smallest enclosing rectangle that is aligned with the coordinate axes and completely encloses the blob. This rectangle is known as the extrema. The Extrema result enables you to retrieve all four coordinates in one command.
