I tried to customise leaflet heatmap.js to render rectangles to generate a heatmap. I was doing good so far. But, there are spacing in between rectangles that I can't get rid of. As in the picture. heatmap

Solutions that I tried: turn off antialiasing, add offset. While adding offset remove the space, it creates an area with "blended color" which I don't want to have. I wonder if there is a solution to remove the gap or remove the blending color in heatmap.js.

Thanks and regards.

Turn out it is precision problem of the leaflet latlong to screen coordinate function. I have fixed it by recalculate the coordinate.
