Image Pixels (U16) is a 2D array of unsigned 16-bit integers containing the pixel values that comprise the image. The first index corresponds to the vertical axis and the second index corresponds to the horizontal axis. The VI resizes Image to be the same size as Image Pixels. Use this input only when Image is an unsigned 16-bit image.

Image is a reference to the source image.

Image Pixels (U8) is a 2D array of unsigned 8-bit integers containing the pixel values that comprise the image. The first index corresponds to the vertical axis and the second index corresponds to the horizontal axis. The VI resizes Image to be the same size as Image Pixels. Use this input only when Image is an unsigned 8-bit image.

Image Pixels (I16) is a 2D array of signed 16-bit integers containing the pixel values that comprise the image. The first index corresponds to the vertical axis and the second index corresponds to the horizontal axis. The VI resizes Image to be the same size as Image Pixels. Use this input only when Image is a signed 16-bit 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.

/images/reference/en-XX/help/370281AG-01/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.

/images/reference/en-XX/help/370281AG-01/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.

/images/reference/en-XX/help/370281AG-01/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.

/images/reference/en-XX/help/370281AG-01/c2dsgl.gif

Image Pixels (Float) is a 2D array of 32-bit floating-point values containing the pixel values that comprise the image. The first index corresponds to the vertical axis and the second index corresponds to the horizontal axis. The VI resizes Image to be the same size as Image Pixels. Use this input only when Image is a 32-bit floating-point image.

/images/reference/en-XX/help/370281AG-01/igenclasstagrefflat.gif

Image Out is a reference to the destination image. If 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.

/images/reference/en-XX/help/370281AG-01/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.

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

/images/reference/en-XX/help/370281AG-01/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.

/images/reference/en-XX/help/370281AG-01/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.
