Explaining Offset of method TileSource.__xyzInRange() #1548

Closed alevangel closed 2 months ago

alevangel commented 2 months ago

Why in the method _xyzInRange of the TileSource class the offstet is calculated in this way? offsetx = x * self.tileWidth * scale

I was expecting to see a sum, rather than a multiplication. offsetx = (x + self.tileWidth) * scale

Just realized that x and y in getTile are not in pixels, but the col/row numebrs (so int)
