Set Row Column (G Dataflow)

Last Modified: June 25, 2019

Changes the intensity values in either a row or a column of pixels in an image.

The data type of the pixels input you select must correspond to the data type of the image in input.

connector_pane_image
datatype_icon

row/column?

Boolean value that defines index as a row number or a column number.

True Column number
False Row number
datatype_icon

image in

Reference to the source image.

datatype_icon

index

Row or column number to replace in the image.

datatype_icon

U8 pixel values

Array of unsigned 8-bit integers containing the new values for the specified row or column of the image.

This input is required if image in is an unsigned 8-bit image.

datatype_icon

U16 pixel values

Array of unsigned 16-bit integers containing the new values for the specified row or column of the image.

This input is required if image in is an unsigned 16-bit image.

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

I16 pixel values

Array of signed 16-bit integers containing the new values for the specified row or column of the image.

This input is required if image in is a signed 16-bit image.

datatype_icon

SGL pixel values

Array of 32-bit floating-point values containing the new values for the specified row or column of the image.

This input is required if image in is a 32-bit floating-point image.

datatype_icon

image out

Reference to the destination image.

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.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

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