Assembly: Cognex.VisionPro.Core (in Cognex.VisionPro.Core.dll) Version: 87.0.0.0
Property Value
Type: BooleanThis property only applies when an acquisition is not in progress (manual or semi-automatic trigger mode before StartAcquire has been called). Once StartAcquire has been called, all backwards motion is accounted for regardless of the value of this property.
When this property is false, acquisition always begins at the encoder position where the previous acquired image completed; you cannot back up and re-acquire an image of the previous part. When this property is true, acquisition begins at the current encoder position when StartAcquire is called. This allows you to re-acquire an image of a part by first reversing the encoder, then calling StartAcquire .
Changes to this property take effect after the next acquisition. This means if you want to be able to back up and re-acquire an image of a part, you must set the property to true before the first image is acquired.
