hdrjpg-sdk-php

The official PHP SDK to convert high dynamic range photos into web-ready HDR files using the hdrjpg.com API.

Install

composer require hdrjpg/hdrjpg-sdk-php

Usage

Each conversion allows for the creation of a custom combination of image sizes, qualities and formats. The supported source HDR image formats are HEIC and EXR. Supported HDR output formats are JPEG-XT, JPEG-XL, AVIF and MP4. All files retain HDR information after the conversion. See hdrjpg.com for more information on compatibility and conversion options.

use TinCat\HdrjpgSdkPhp\Client;
$client = new Client('iS1nrfLP7KSCkeVlb1hKUL39eyUHsjE+KnLwmh6j'); // Replace with your API Key
$client->convert(
    'example.heic', // Complete path for your Source HDR image file
    [ // An array of variants
        [ // Each variant defines the settings for each resulting image
            'width' => 1200,
            'baseQuality' => 98,
            'format' => 'jpeg-xt'
        ],
        [
            'width' => 800,
            'baseQuality' => 98,
            'format' => 'jpeg-xt'
        ],
        [
            'width' => 300,
            'baseQuality' => 98,
            'gainmapQuality' => 95,
            'format' => 'jpeg-xt'
        ],
        [
            'width' => 1200,
            'baseQuality' => 98,
            'format' => 'jpeg-xl'
        ],
        [
            'height' => 300,
            'baseQuality' => 98,
            'fileName' => 'image-converted',
            'format' => 'avif'
        ],
        [
            'height' => 300,
            'baseQuality' => 98,
            'format' => 'mp4'
        ]
    ],
    '/tmp' // Output directory to save resulting files to
);

This method will wait for the conversion to be completed, and can take up to a few minutes depending on the size of the source image and the variants and formats requested.

Advanced usage

Conversion is internally a three steps process that can be leveraged individually to better suit your implementation workflow. If you need finer control over this process, see the file examples/advanced-convert.php for an example on how to perform the conversion steps separately.
