    ->options(new BlurAreas(
        10,
        [0.1, 0.1, 0.3, 0.2],
        [0.6, 0.5, 0.2, 0.2],
    ));

$url->build();
// _/ba:10:0.1:0.1:0.3:0.2:0.6:0.5:0.2:0.2/plain/https%3A%2F%2Fexample.com%2Fimage.jpg

The option appears in the URL as ba:10:0.1:0.1:0.3:0.2:0.6:0.5:0.2:0.2.

Parameters

Parameter	Type	Default	Description
`$sigma`	`float`	required	Size of the blur mask, greater than 0.
`$areas`	`array ...`	—	Any number of areas, each an array of `left`, `top`, `width` and `height`, as values from 0 to 1 relative to the source.

A dash means the argument can be left out. Trailing arguments that are left out or null are dropped from the URL, while a null before a given argument leaves an empty slot, so the following arguments keep their position.

Notes

An area that does not consist of exactly four values throws an InvalidArgumentException.
Coordinates respect the EXIF orientation of the source.
