I don't understand what you want to do. "-resize" will resize an image, but then there is no question of centering it.

i need to resize canvas, not image

You need to explain further; I recommend you post a graphical example of what you want.

-extent can increase canvas size and -gravity center will center the image on the background.

-size will create a canvas
