Window Grid (G Dataflow)

Last Modified: October 24, 2017

Obtains or modifies the status of the grid.

If enabled, the grid is invisible and drawn ROIs will be constrained to it. The grid can be used to help trace a region of interest accurately. This node is not supported on ETS targets or VxWorks targets.

connector_pane_image
datatype_icon

grid size in

New size of the grid if get/set? is TRUE. Otherwise, the node ignores this input.

datatype_icon

X Offset

Horizontal offset of the grid.

datatype_icon

Y Offset

Vertical offset of the grid.

datatype_icon

get/set?

Control specifying whether to retrieve (Get) or modify (Set) the step values for the grid.

True Set (modify)
False Get (retrieve)

Default: True

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

grid size out

Size of the current grid.

datatype_icon

X Offset

Horizontal offset of the grid.

datatype_icon

Y Offset

Vertical offset of the grid.

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
