                'attribute' => 'image_id',
            ],

                'required' => false,
                'image' => true,

PNG Compression

To switch-on compression for png-images install https://pngquant.org. Then add to console controller action ImageCompressor::compressPngThumbs($path);, where $path is path to thumbnails folder and setup cron task from user which creates files, for example www-data(crontab -u www-data -e).

Adding watermarks to thumbnails

To add watermark while creating FPM::ACTION_ADAPTIVE_THUMBNAIL, FPM::ACTION_THUMBNAIL or FPM::ACTION_CANVAS_THUMBNAIL config must be like this:

'sliderThumb' => [
                        'action' => FPM::ACTION_THUMBNAIL,
                        'width' => 330,
                        'height' => 330,
                        'watermark' => [
                            'fileName' => $wmarkPath,
                            'point' => [
                                'x' => 0,
                                'y' => 0,
                            ],
                            'size' => [
                                'width' => 330,
                                'height' => 330,
                            ]
                        ],
                    ],

where 'point' (coordinates of point on originap image where to place watermark) and 'size' (size of watermark's thumbnail if it larger then original image) are optional, only 'fileName' is required. If watermark size is larger then original image - it will not be pasted into original image. To fix this - module will create thumbnail of watermark with original image size to fit it.

Change quality of images

To change quality of thumbnail you need to specify quality property in config:

'thumbImage' => [
    'action' => FPM::ACTION_THUMBNAIL,
    'width' => 330,
    'height' => 330,
    'quality' => 75,
],

This property must be an integer in range from 0 to 100.
