Create an all-zero grayscale image

How to create an all-zero grayscale image? I think this question is stupid but please show me the correct and efficient way. Thanks!

Use IMAQ Create to create the image.

Use IMAQ SetImageSize to make the image the dimensions you want.

Use IMAQ FillImage to set the color of the entire image.

The other way is to create 2D array by initializing with 0 values and the row and index as image size and convert to image.
