IMAQ Or VI

Owning Palette: OperatorsInstalled With: NI Vision Development Module

Performs an OR or NOR operation on two images or an image and a constant.

IMAQ Or

cbool.gif

Or/Nor (Or) specifies which logic operation the VI performs. If set to TRUE, the result of the OR is inverted, producing a NOR. The default is FALSE, which specifies an OR operation.

Image Src A is a reference to the first source image.

Image Dst is a reference to the destination image. If Image Dst is connected, it must be the same size as Image Src A.

Image Src B is the reference to the second source image.

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.

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.

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.

ci32.gif

Constant is the value used for image-constant operations. The default is 0.

Image Dst Out is the reference to the destination (output) image that receives the processing results of the VI. If the Image Dst is connected, Image Dst Out is the same as Image Dst. Otherwise, Image Dst Out refers to the image referenced by Image Src A.

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.

Details

All connected images must be the same image type. An operation between an image and a constant occurs when Image Src B is not connected.

This VI is performed for each pixel (x, y) in the following manner:

If two images are connected on input, then Dst(x, y) = SrcA(x, y) OR SrcB(x, y).

If Image Src B is not connected, then Dst(x, y) = SrcA(x, y) OR Constant.
