Re: Dislocated Mercator Projection

Hi Orlando,

What scale is the map that you are looking at? Does the error decrease
when you zoom in? You may be seeing the effects of rounding that the
projection is doing at smaller scales, setting a pixel's coordinates to
some value, while rounding other lat/lon values to that closest pixel as
well.
