pixelXToTileX method

int pixelXToTileX(
  1. double pixelX
)

Converts a pixel X coordinate to the tile X number.

@param pixelX the pixel X coordinate that should be converted. @param zoomLevel the zoom level at which the coordinate should be converted. @return the tile X number.

Implementation

int pixelXToTileX(double pixelX) {
  assert(pixelX >= 0);
  assert(pixelX <= _mapSize);
  return min(pixelX / tileSize, scalefactor.scalefactor - 1).floor();
}
