Simple Image Storage

Image storage for Nette.

Installation

Download a latest package or use Composer:

composer require inteve/simple-image-storage

Library requires PHP 5.6.0 or later.

Usage

use Inteve\SimpleImageStorage\ImageStorage;

Register in config

parameters:
	imageStorage:
		directory: %wwwDir%
		publicDirectory: @httpRequest::getUrl()::getBaseUrl()
		storageName: images # optional

services:
	- Inteve\SimpleImageStorage\ImageStorage(%imageStorage.directory%, %imageStorage.publicDirectory%, %imageStorage.storageName%)

Store image

<?php
$image = $imageStorage->upload($fileUpload);
// $image = 'image-name.jpg'

$avatar = $imageStorage->upload($fileUpload, 'upload/avatars');
// $avatar = 'upload/avatars/image-name.jpg';

Delete image

<?php
$imageStorage->delete('upload/avatar/image-name.jpg');

Get original path

<?php
$path = $imageStorage->getRealPath('upload/avatar/image-name.jpg');

Get original public path

<?php
$path = $imageStorage->getPublicPath('upload/avatar/image-name.jpg');

Thumbnails

<?php
$path = $imageStorage->thumbnail($file, $width, $height, $flags = NULL, $quality = NULL);
$path = $imageStorage->thumbnail('upload/avatar/image-name.jpg', 512, 256);

It uses Nette\Utils\Image by default but you can provide custom thumbnail generator in constructor:

$imageStorage = new ImageStorage(..., ..., ..., function ($sourcePath, $outputPath, array $thumbnailData) {
	$im = new Imagick;
	$im->readImage($sourcePath);
	$im->crop(...);
	$im->writeImage($outputPath);
});
  • string $sourcePath - path to original image
  • string $outputPath - thumbnail path
  • array $thumbnailData
    • int|NULL width - width of thumbnail or NULL
    • int|NULL height - height of thumbnail or NULL
    • int|NULL quality - quality of output image or NULL
    • int flags - see constants ImageStorage::SHRINK_ONLY, STRETCH, FIT, FILL & EXACT

In template

class BasePresenter extends Nette\Application\UI\Presenter
{
	/** @var  Inteve\SimpleImageStorage\ImageStorage  @inject */
	public $imageStorage;


	protected function beforeRender()
	{
		parent::beforeRender();
		$this->template->img = $this->imageStorage;
	}
}
<img src="{$img->thumbnail($avatar, 512, 256)}">
<img src="{$img->thumbnail($avatar, 512, 256, $img::SHRINK_ONLY)}">
<img src="{$img->thumbnail($avatar, 512, 256, $img::STRETCH)}">
<img src="{$img->thumbnail($avatar, 512, 256, $img::FILL)}">
<img src="{$img->thumbnail($avatar, 512, 256, $img::EXACT)}">
