Usage
Defining image types
<?php class MyImageType { const ORIGINAL = ""; const FULLSIZE = "fullsize"; const WIDE = "wide"; const SQUARE = "square"; }
Defining thumbnailer creation
<?php use iodev\Lib\Thumbnails\ThumbnailBuilder; use iodev\Lib\Thumbnails\Thumbnailer; use iodev\Lib\Thumbnails\ThumbnailerBuilder; class MyImageFactory { /** * @return Thumbnailer */ public static function createThumbnailer() { return ThumbnailerBuilder::create() ->setCommonResolver($_SERVER["DOCUMENT_ROOT"], "/files/content-by-id") ->setPrimaryThumbnailName(MyImageType::ORIGINAL) ->addThumbnail( ThumbnailBuilder::create() ->name(MyImageType::ORIGINAL) ->size(4096, 4096) ->modeContain() ->formatSource() ->toThumbnail() ) ->addThumbnail( ThumbnailBuilder::create() ->name(MyImageType::FULLSIZE) ->size(4096, 4096) ->modeContain() ->formatSource() ->watermarkAdaptive("watermark.png") ->toThumbnail() ) ->addThumbnail( ThumbnailBuilder::create() ->name(MyImageType::WIDE) ->size(1280, 720) ->modeCover() ->formatJpeg(95) ->watermarkAdaptive("watermark.png") ->toThumbnail() ) ->addThumbnail( ThumbnailBuilder::create() ->name(MyImageType::SQUARE) ->size(150, 150) ->modeCover() ->formatPng() ->toThumbnail() ) ->toThumbnailer(); } }
Defining image class
<?php use iodev\Lib\Thumbnails\Thumbnailer; class MyImage { /** @var Thumbnailer */ private static $_thumbnailer = null; /** * @return Thumbnailer */ public static function getThumbnailer() { if (self::$_thumbnailer == null) { self::$_thumbnailer = MyImageFactory::createThumbnailer(); } return self::$_thumbnailer; } /** * @param string $path */ public function __construct( $path ) { $m = new MyImage(); $m->path = $path; return $m; } /** @var string */ public $path = ""; /** * @return string */ public function toUri( $imageType="" ) { return self::getThumbnailer() ->resolveLocationByName($this->path, $imageType); } /** * @return string */ public function toFullsizeUri() { return $this->toUri(MyImageType::FULLSIZE); } /** * @return string */ public function toWideUri() { return $this->toUri(MyImageType::WIDE); } /** * @return string */ public function toSquareUri() { return $this->toUri(MyImageType::SQUARE); } }
Uploading on form submitting
<?php // For example: you need to thumbnail main image of some article. So content ID it's article ID :) $contentId = 123; $inputName = "image-file-form-input-name"; $areaSet = null; $overlayWatermarks = true; $thumbnailer = MyImage::getThumbnailer(); $result = $thumbnailer->thumbnailFormInput($contentId, $inputName, $areaSet, $overlayWatermarks); // thumbnailed image path to store to somewhere $path = $result->getPrimaryPath(); $myThumbnailedImage = new MyImage($path);
Updating
<?php $contentId = 123; $oldPath = "previous-generated-thumbnail-path.jpg"; $areaSet = null; $overlayWatermarks = false; $thumbnailer = MyImage::getThumbnailer(); $result = $thumbnailer->reThumbnailPath($contentId, $oldPath, $areaSet, $overlayWatermarks); // thumbnailed image path to save $newPath = $result->getPrimaryPath(); $myThumbnailedImage = new MyImage($newPath);
Using thumbnailed images
<?php $image = new MyImage("saved-thumbnailed-path.jpg"); // original echo $image->toUri(); // fullsized watermarked echo $image->toFullsizeUri(); // wide watermarked echo $image->toWideUri(); // square echo $image->toSquareUri();
