IMAQ Browser Setup VI

Owning Palette: BrowserInstalled With: NI Vision Development Module

Configures the browser. This VI sets all the required parameters that determine the aspect and the thumbnail organization on the browser. You create and configure a browser using this VI. These tasks are mandatory because all the functions in this library act on browsers and not on standard images.

Note  This VI is not supported on ETS targets or VxWorks targets.

Examples

IMAQ Browser Setup

Image In is the 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.

Browser Info is the cluster configuring the initial aspect of the browser. This cluster contains the following parameters:

cnclst.gif

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

ci32.gif

X is the width to make the browser.

ci32.gif

Y is the height to make the browser.

ci32.gif

Images per Line is the number of thumbnail images per line on the browser.

cu32.gif

Background Color is the color filling the background of the browser.

ci32.gif

Frame Size is the width of the frame that contains each thumbnail.

cenum.gif

Frame Style defines the frame style of the browser. You can choose from the following frame styles:

  • Raised
  • Beveled
  • Outline
  • Hidden
  • Step
  • Raised Outline
csgl.gif

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

error in (no error) describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

cbool.gif

status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.

ci32.gif

code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.

cstr.gif

source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

Image Browser Out is the configured browser image.

ii32.gif

Images per Line is the number of thumbnail images per line on the browser.

ii32.gif

Images per Column is the number of thumbnail images per column on the browser.

ierrcodeclst.gif

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.

ibool.gif

status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.

ii32.gif

code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.

istr.gif

source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
