Installation
To install via Composer, use the command below, it will automatically detect the latest version and bind it with ^
.
composer require wyrihaximus/tile-stitcher
Usage
The stitcher needs two things:
- Tile dimensions, it assumes they are all the same size
- A list of tile files to stitch together
<?php declare(strict_types=1); use Intervention\Image\Drivers\Gd\Driver; use Intervention\Image\ImageManager; use WyriHaximus\TileStitcher\Coordinate; use WyriHaximus\TileStitcher\Dimensions; use WyriHaximus\TileStitcher\FileLoader; use WyriHaximus\TileStitcher\Stitcher; use WyriHaximus\TileStitcher\Tile; $tiles = [ new Tile( new Coordinate(69, 69), new FileLoader('map/69_69.png'), ), new Tile( new Coordinate(70, 69), new FileLoader('map/70_69.png'), ), ]; $stitcher = new Stitcher( new ImageManager( new Driver(), ), ); $image = $stitcher->stitch( 'image/png', Map::calculate( new Dimensions(512, 512), ...$tiles, ), ); file_put_contents('output/two_tile.png', $image);
The result:
Advanced
Loaders
The main goal of this package is to take tiles and stitch them together into one, there for all I/O bound operations
have not place in this package. However we can't ignore the fact that we need to load tile images from somewhere. And
since some maps can be massive the LoaderInterface
is included to do reading I/O. A FileLoader
is included in this
package to provide the most basic implementation. (And, well, not ship a package without being fully functional 😅.)
For example this is an implementation using react/filesystem
:
use React\Filesystem\Node\FileInterface; use function React\Async\await; final readonly class ReactFileLoader implements LoaderInterface { public function __construct(private FileInterface $file) { } public function load(): string { return await($this->file->getContents()); } }
This is an example using Flysystem
unlocking S3 and a whole range of
different storage systems:
use League\Flysystem\Filesystem; final readonly class FLysystemFileLoader implements LoaderInterface { public function __construct(private Filesystem $filesystem, private string $path) { } public function load(): string { return $this->filesystem->read($this->path); } }
Locators
Locators can be used in stead of passing a static list of tile objects to the Map::calculate
as a way to handle more
dynamic use cases. This package ships with the CallalbleTileLocator
to aid with average day usage of this package.
It will pass the path you give it plus the file name into the callable you pass it. The callable can either return a
Tile
or null on no-op. And it will never go deeper than one level.
$image = $stitcher->stitch( 'image/png', Map::calculate( new Dimensions(512, 512), new CallalbleTileLocator( 'map/', static function (string $fileName): Tile { $fileNameWithoutExtension = str_replace('.png', '', basename($fileName)); $coords = explode('_', $fileNameWithoutExtension); return new Tile( new Coordinate( ...array_map('intval', $coords), ), new FileLoader($fileName), ); } ), ), );
Any implementation of the TileLocatorInterface
is only expected to return an iterable of Tile
instances. The Map
will only iterate over it once.
Todo
-
Map::calculateMap
method to calculate the size of the resulting map image -
Switcher::stitch
method to take theMap
and stitch it together into an image - Pick up desired image format from render output argument, it's PNG only now
- Support pointing at directory and pick up all images utilizing a callable to parse coordinates
- Switch to abstraction layer for image operations
- Reduce direct I/O in this package by providing a loader interface and outputting the resulting image as string by MIME type
- Automatically resize tiles to the desired tile size
