    ->options(new AutoQuality('dssim', 0.02, 40, 90));

$url->build();
// _/aq:dssim:0.02:40:90/plain/https%3A%2F%2Fexample.com%2Fimage.jpg

The option appears in the URL as aq:dssim:0.02:40:90.

Parameters

Parameter	Type	Default	Description
`$method`	`string`	—	The method used to compare results, such as `size` or `dssim`.
`$target`	`float`	—	The quality target of the method.
`$minQuality`	`int`	—	Lowest quality to try.
`$maxQuality`	`int`	—	Highest quality to try.
`$allowedError`	`float`	—	Tolerated deviation from the target.

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

All arguments are optional. See the imgproxy reference for the available methods.
