AND (G Dataflow)

Last Modified: June 25, 2019

Performs an AND or NAND operation on two images or on an image and a constant.

connector_pane_image
datatype_icon

image src a

Reference to the first source image.

datatype_icon

image dst

Reference to the destination image.

If image dst is connected, it must be the same size as image src a.

datatype_icon

image src b

Reference to the second source image.

datatype_icon

constant

Value used for image constant operations.

constant must be a RGB color value when image src a is a color image.

Default: 0

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

AND/NAND?

Logic operation the node performs.

TRUE The result of the AND is inverted, producing a NAND.
FALSE Specifies an AND operation.

Default: FALSE

datatype_icon

image dst out

Reference to the destination image that receives the processing results of the node.

If image dst is connected, image dst out is the same as image dst. Otherwise, image dst out refers to the image referenced by image src a.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

AND Behavior

All connected images must be the same image type. An operation between an image and a constant occurs when image src b is not connected.

This node is performed for each pixel (x, y) in the following manner:

If two images are connected on input, then Dst(x, y) = SrcA(x, y) AND SrcB(x, y).

If image src b is not connected, then Dst(x, y) = SrcA(x, y) AND Constant.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
