Deletes an image from the browser.

Set only one of the following controls: index in, matrix indexes in, or pixel position in. After deleting an image, the browser reorganizes the remaining images by filling the free space or leaving it vacant. This node is not supported on ETS targets or VxWorks targets.

connector_pane_image
datatype_icon

browser image in

RGB image that the browser uses.

datatype_icon

index in

Position of the image to delete.

datatype_icon

matrix indexes in

Column, line position of the image to delete.

datatype_icon

pixel position in

Pixel coordinates of the area or image to delete.

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

reorganization mode

Remapping mode of the browser.

datatype_icon

browser image out

Browser image that results from the inputs.

datatype_icon

index out

Index of the browser position of the deleted thumbnail.

datatype_icon

matrix indexes out

Column, line position of the removed thumbnail.

datatype_icon

pixel position out

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

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
