How to curve a number in canvas

I’m doing a test of a billiards game in 2D canvas, but I can’t curve the numbers on the balls, I can rotate and shrink them, but I’m not able to bend them, by bending them I mean like the human back, which is not completely straight , but it has a curve, when a number is in the corners of the ball from the center where you look at the ball, the number should be curved, but I can’t find the answer to achieve that.
