Image Mask is an 8-bit image that specifies the region of the small image that will be copied. Only those pixels in the Image Src (Small) image that correspond to an equivalent non-zero pixel in the mask image are copied. All other pixels keep their original values. The entire image is processed if Image Mask is not connected.

Color Mode defines the image color format to use for the operation. Choose from the following values:

Note  Unsigned 64-bit RGB images support only a Color Mode of RGB.
RGB (0)

(Default) Specifies the color format RGB (red, green, and blue)

HSL (1)

Specifies the color format HSI (hue, saturation, and luminance)

HSV (2)

Specifies the color format HSV (hue, saturation, and value)

HSI (3)

Specifies the color format HSI (hue, saturation, and intensity)

Image Src is a reference to the source image.

Image Dst is a reference to the destination image.

Red or Hue Lookup Table is the LUT applied to the first color plane, depending on the Color Mode. This array can contain a maximum of 256 elements. The array is filled automatically when you specify fewer than 256 elements. This procedure does not change pixel values that are not explicitly specified from the values of the LUT you input. By default this array is empty, and no replacement occurs on this plane.

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.

Green or Sat Lookup Table is the LUT applied to the second color plane, depending on the Color Mode. This array can contain a maximum of 256 elements. The array is filled automatically when you specify fewer than 256 elements. This procedure does not change pixel values that are not explicitly specified from the values of the LUT you input. By default this array is empty, and no replacement occurs on this plane.

Blue or Luma or Val or Inten Lookup Table is the LUT applied to the third color plane, depending on the Color Mode. This array can contain a maximum of 256 elements. The array is filled automatically when you specify fewer than 256 elements. This procedure does not change pixel values that are not explicitly specified from the values of the LUT you input. By default this array is empty, and no replacement occurs on this plane.

Image Dst 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.

ibool.gif

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.
