Hi, I am trying to draw dominos using metapost and ConTeXt. I borrow part of the code in Threeddice.mp by Dan Lueking for drawing dots. To display blank dominos where I want and drawing one domino work well but drawing several dominos where I want is not working well. (compare domino0 and domino1 in the example) Why do the dominos overlap or locate on the wrong place? Thank you for reading. Best regards, Dalyoung
