Center an object within an image with a solid background. Do this by first trimming the background around the object (e_trim) and then pad (c_lpad) and resize the canvas to the image's initial width (w_iw) and height (h_ih).

* A green border was added (bo_4px_solid_green) to better demonstrate the object position within the image.

And here it is after trimming, padding, and resizing:
