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 portion of the image to get. A value of 0 specifies the entire width of the image (x must also be 0).

height: Type: System Int32
