Tilemap Canvas Size

[homeslice247]

Hey everyone,

I am new to the 2D Toolkit and trying to figure out tilemaps.

When painting, the 0, 0 point is on the bottom left of the canvas. I noticed when resizing the canvas it adds onto the right and top.

What happens if I wanted to add to the canvas to the left or bottom, or would I have to shift all of my tiles up and to the right if I want to add more below it later on?

Is there a way to center the canvas origin so it adds on all sides when changing its dimensions?

Thanks!
