Parameters

dataMode: Type: Cognex.VisionPro CogImageDataModeConstants
Specifies whether the pixel data are read, write, or read/write.

x: Type: System Int32
The x-coordinate of the portion of the image to get.

y: Type: System Int32
The y-coordinate of the portion of the image to get.

width: Type: System Int32
The width of the image to get.

height: Type: System Int32
The height of the image to get.

pixelMemory: Type: Cognex.VisionPro ICogImage8PixelMemory
An object that represents the pixel data.

Implements

ICogImage8Root GetRawPixelMemory(CogImageDataModeConstants, Int32, Int32, Int32, Int32, ICogImage8PixelMemory )

Exceptions

Exception	Condition
NullReferenceException	pixelMemory is NULL. (C++ only)

Remarks

Gets an object that can be used to directly access the raw pixel data.

Note: This method is intended for Cognex use only. To access the pixel data directly, use CogImage8Grey.Get8GreyPixelMemory(CogImageDataModeConstants, Int32, Int32, Int32, Int32) instead.
