Parameters

dataMode: Type: Cognex.Vision ImageDataModeConstants
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.Vision IImage8PixelMemory
(output param) An object that represents the pixel data.

Implements

IImage8Root GetRawPixelMemory(ImageDataModeConstants, Int32, Int32, Int32, Int32, IImage8PixelMemory )

Exceptions

Exception	Condition
ImageException	This Root Image has not been initialized.
ImageException	x, y, width, and height do not describe a region that is fully contained within this image.

Remarks

This method is intended for Cognex use only. To access the pixel data directly, use Image8Grey's Get8GreyPixelMemory() instead.
