Interface for specifying the region of interest for image acquisition.
Namespace: Cognex.VisionProAssembly: Cognex.VisionPro.Core (in Cognex.VisionPro.Core.dll) Version: 65.1.0.0
Syntax
The ICogAcqROI type exposes the following members.
Methods
| Name | Description | |
|---|---|---|
 | GetROIXYWidthHeight | Gets the ROI. The ROI allows a subset of the pixels defined by the video format to be returned by a call to CompleteAcquire. |
| IsROIModeSupported | Returns True if the corresponding mode setting is supported. |
| SetROIXYWidthHeight | Sets the ROI. |
Properties
| Name | Description | |
|---|---|---|
 | ROIMode | Gets or sets the ROIMode. |
Remarks
Interface for specifying the region of interest (ROI) for image acquisition.
The ROI property lets you specify which part of the acquired image you wish to process. The ICogAcqFifo interface uses the ROI property to optimize acquisition time.
Depending on the capabilities of the video hardware, the ROI setting may affect which pixels are actually written in the pixel root image, allowing the acquisition FIFO to acquire a smaller number of pixels, thereby reducing acquisition time.
Supported on: 8100D, 8100M, 8100M+, 8120/CVM1, 8120/CVM6, 8120/CVM9, 8120/CVM11, 8501, 8504 8600
