ImageTiletype

A map tile: its size in pixels and its picture. A map source's detail is the pixels across the whole circumference (not a level number, because the packages number their pyramids differently), and each source maps a width to its own nearest level.

Import it

import type { ImageTile } from "@johnmorrisdotca/hoshi-stars/door";

Definition

interface ImageTile {
    width: number;
    height: number;
    image: BitmapLike;
}
