Line Coordinates is a four-element array specifying the pixel coordinates that form the end points of the line to modify. The first two elements (left, top) in the array correspond to the coordinates for the first endpoint of the line. The last two elements (right, bottom) correspond to the second endpoint of the line.

If the size of the Pixels Line is greater than the number of pixels on the straight line between the Line Coordinates, the remaining pixel values in the Pixels Line will not be used. If the size of the Pixels Line is smaller than the number of pixels on the straight line between the Line Coordinates, The pixel values are changed starting from the (left, top) pixel and continuing until all of the elements in the Pixel Line are used. Any remaining pixels on the straight line between the Line Coordinates will not be modified.

Image is a reference to the source image.

Pixels Line (U8) is an array of unsigned 8-bit integers containing the new values for the pixel line. This input is required if Image is an unsigned 8-bit image.

Pixels Line (I16) is an array of signed 16-bit integers containing the new values for the pixel line. This input is required if 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.

	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.
	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.

Pixels Line (Float) is an array of 32-bit floating point values containing the new values for the pixel line. This input is required if Image is a 32-bit floating-point image.

Pixels Line (U16) is an array of unsigned 16-bit integers containing the new values for the pixel line. This input is required if Image is an unsigned 16-bit image.

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.

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.
	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.
	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.
