The method getLevel() does not exist on Jackal\ImageMerge\Command\Options\CommandOptionInterface. It seems like you code against a sub-type of Jackal\ImageMerge\Command\Options\CommandOptionInterface such as Jackal\ImageMerge\Command\Options\LevelCommandOption.

        if (!$level) {
            return $image;
        }

        $resource = $image->getResource();

        // start from the top-left pixel and keep looping until we have the desired effect
        for ($y = 0;$y < $image->getHeight();$y += $level + 1) {
            for ($x = 0;$x < $image->getWidth();$x += $level + 1) {
                // get the color for current pixel
                $rgb = imagecolorsforindex($resource, imagecolorat($resource, $x, $y));

                // get the closest color from palette
                $color = imagecolorclosest($resource, $rgb['red'], $rgb['green'], $rgb['blue']);
                imagefilledrectangle($resource, $x, $y, $x + $level, $y + $level, $color);
            }
        }

        return $image;
