Setup Browser (G Dataflow)

Last Modified: June 25, 2019

Configures the browser. This node sets all the required parameters that determine the aspect and the thumbnail organization on the browser.

You create and configure a browser using this node. These tasks are mandatory because all the functions in this library act on browsers and not on standard images.

This node is not supported on ETS targets or VxWorks targets.

connector_pane_image
datatype_icon

image in

RGB image used by the browser. This image forms the base of the browser. All thumbnails placed in the browser are pasted onto this image.

datatype_icon

browser options

Cluster configuring the initial aspect of the browser.

This cluster contains the following parameters:

datatype_icon

Browser Size

Size of the browser in pixels, where X is the width and Y is the height.

datatype_icon

X

Width to make the browser.

datatype_icon

Y

Height to make the browser.

datatype_icon

images per line

Number of thumbnail images per line on the browser.

datatype_icon

Background Color

Color filling the background of the browser.

datatype_icon

Frame Size

Width of the frame that contains each thumbnail.

datatype_icon

Frame Style

Frame style of the browser.

You can choose from the following frame styles:

  • Raised
  • Beveled
  • Outline
  • Hidden
  • Step
  • Raised Outline
datatype_icon

scaling ratio

Width/height ratio of the thumbnail images of the browser. This value is 3/2 for PAL images and 4/3 for NTSC images.

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

browser image out

Configured browser image.

datatype_icon

images per line

Number of thumbnail images per line on the browser.

datatype_icon

images per column

Number of thumbnail images per column on the browser.

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
