cerrcodeclst

error in (no error)

The error in cluster can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.

The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

    cbool

    		status

    The status boolean is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning.

    The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

    ci32

    		code

    The code input identifies the error or warning.

    The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

    cstr

    		source

    The source string describes the origin of the error or warning.

    The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

GpuMat Pointer

Memory description of a CUDA memory for zero-copy interop.

    cu64

    		CudaPtr

    The Gpu memory address of the first pixel in the image (top-left, coordinate 0,0)

    ci64

    		Step

    Also known as the Stride or Line Pitch. This represents the number of bytes between the start of one row and the start of the next row

    cu64

    		TotalBytes

    The total physical footprint of the image in RAM. It is calculated as step * rows

    ci32

    		Cols

    The horizontal width of the image in pixels

    ci32

    		Rows

    The vertical height of the image in pixels

    ci32

    		ElemSize

    The number of bytes occupied by a single pixel

    cenum

    		cvType

    The internal OpenCV integer constant representing the data format

    ci32

    		Channels

    The number of components per pixel

    cu64

    		handlePtr

    An opaque 64-bit pointer to allocated cv::cuda::HostMem instance that maintains a +1 reference count on the underlying memory payload.

    cu64

    		releaseCallbackPtr

    C-convention function pointer that must be invoked with the handlePtr to safely decrement the OpenCV reference count and deallocate the handle.

ierrcodeclst

error out

The error out cluster passes error or warning information out of a VI to be used by other VIs.

The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

    ibool

    		status

    The status boolean is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning.

    The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

    ii32

    		code

    The code input identifies the error or warning.

    The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

    istr

    		source

    The source string describes the origin of the error or warning.

    The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
