Quick examples

Pixaven API enables you to provide your images for processing in two ways - by uploading them directly to the API (Image Upload) or by providing a publicly available image URL (Image Fetch).

You may also choose your preferred response method on a per-request basis. By default, the Pixaven API will return a JSON response with rich metadata pertaining to input and output images. Alternatively, you can use binary responses. When enabled, the API will respond with a full binary representation of the resulting (output) image. This PHP integration exposes two convenience methods for interacting with binary responses: toFile() and toBuffer().

Image upload

Here is a quick example of uploading a local file for processing. It calls toJSON() at a final step and instructs the API to return a JSON response.

<?php

// Pass your Pixaven API Key to the constructor
$pix = new Pixaven\Pixaven('your-api-key');

// Upload an image from disk, resize it to 100 x 75,
// automatically enhance, and adjust sharpness parameter.
$pix
    ->upload('path/to/input.jpg')
    ->resize(array(
        'width' => 100,
        'height' => 75
    ))
    ->auto(array(
        'enahnce' => true
    ))
    ->adjust(array(
        'unsharp' => 10
    ))
    ->toJSON(function ($error, $meta) {
        if (!empty($error)) {
            throw new Exception($error);
        }

        // You'll find the full JSON metadata within the `meta` variable
    });

Image fetch

If you already have your source visuals publicly available online, we recommend using Image Fetch by default. That way you only have to send a JSON payload containing image URL and processing steps. This method is also much faster than uploading a full binary representation of the image.

<?php

// Pass your Pixaven API Key to the constructor
$pix = new Pixaven\Pixaven('your-api-key');

// Provide a publicly available image URL with `fetch()` method,
// apply Gaussian blur using PNG as the output format.
// We'll also use `toFile()` method and stream the output image to disk
$pix
    ->fetch('https://www.website.com/image.jpg')
    ->filter(array(
        'blur' => array(
            'mode' => 'gaussian',
            'value' => 10
        )
    ))
    ->output(array(
        'format' => 10
    ))
    ->toFile('path/to/output.png', function ($error, $meta) {
        if (!empty($error)) {
            throw new Exception($error);
        }

        // You'll find the full JSON metadata within the `meta` variable
    });
