Last Modified: June 25, 2019

Gets or sets the status of images on the browser.

You can choose either of the possible status values: selected or not selected. Selected images are framed using the Focus Color (refer to the Setup Browser Focus node description). This node is not supported on ETS targets or VxWorks targets.

connector_pane_image
datatype_icon

state in

Image status value.

datatype_icon

browser image in

RGB image that the browser uses.

datatype_icon

index in

Position of the image to select or deselect.

datatype_icon

matrix indexes in

Column, line position of the image to select or deselect.

datatype_icon

pixel position in

Pixel coordinates of the area of the image to select or deselect.

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

selection mode

Modes: multiple selection or single selection.

datatype_icon

get/set?

Boolean value that specifies whether you want to get or set the status of images on the browser.

True Set the status.
False Get the status.

state out

Image status.

datatype_icon

browser image out

Browser image that results from the inputs.

datatype_icon

index out

Index of the browser position of the selected thumbnail.

datatype_icon

matrix indexes out

Column, line position of the selected thumbnail.

datatype_icon

pixel position out

x- and y-coordinates of the topmost-leftmost pixel and bottommost-rightmost pixel of the position of the selected thumbnail.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
