README

Simple Map Tiles Generator allow to make a Map Tiles with PHP and Imagick. That allows to build a simple custom map. It does not include any geographical calculations.

Requirements

PHP >= 5.3 version
PHP Imagick extension >= 3.0 version
A lot CPU time (for images with high resolution and for high zoom level)
A lot free disc space
Patience ;)

Usage example

Make custom map, based on my-image.jpg.

Generate a tiles:

// Setup
$tiler = new Fedik\MapTiles\MapTiles('/full/path/to/my-image.jpg', array(
  'tiles_path' => '/full/path/to/where-to-store-tiles/',
  'zoom_max' => 3
));

// Generate tiles
$tiler->process(true);

Display the result with Leaflet.js

<html>
<head>
  <link rel="stylesheet" href="path/to/leaflet.css" />
  <script src="path/to/leaflet.js"></script>
    
  <script type="module">
      const tiles = L.tileLayer('tiles-path/{z}/{x}/{y}.jpg', {
          minZoom: 0,
          maxZoom: 5,
          tms: true
      });

      const map = L.map('map', {
          center: [0, 0],
          zoom: 1,
          layers:[tiles]
      });
  </script>
</head>
<body>
  <div id="map" style="height: 100vh"></div>  
</body>
</html>
