I managed to reproduce the same result as MapBox by introducing magnify method.. It is working for all scenarios of GeoJSON I used. Not sure why I had to magnify/zoom though.
def draw(self, mapbox_image, zoom, **kwargs) -> None:
geometries = get_geometries(kwargs['geojson'])
left_x = kwargs['left_x']
top_y = kwargs['top_y']
actual_x_padding = kwargs['actual_x_padding']
actual_y_padding = kwargs['actual_y_padding']
draw = ImageDraw.Draw(mapbox_image)
for geometry in geometries:
for coordinates in geometry['coordinates']:
polygon = [(self.magnify(longitude_to_x(coordinate[0], zoom) - left_x, 100),
self.magnify(latitude_to_y(coordinate[1], zoom) - top_y, 100)) for coordinate in
coordinates]
draw.polygon(polygon, fill=None, outline="blue")
def magnify(self, value, magnification):
return value + (value * magnification) / 100
