Quality must be in range 0 to 100

Error message

Quality must be in range 0 to 100

What it means

JxlEncoder validates its $quality constructor option and throws InvalidArgumentException unless it is an integer from 0 to 100. Options are forwarded from the generic APIs, so $image->save('out.jxl', quality: N) reaches this constructor via Format::encoder(...$options). The range check runs in the shared constructor before driver specialization, so it fires even on the GD driver, although JXL output ultimately requires Imagick.

Solutions

  1. Clamp the value into range: max(0, min(100, $quality))
  2. Validate quality where it enters your application (form request, DTO, config loader)
  3. Confirm any 0-1 float scale is converted before passing: (int) round($f * 100)

Example fix

// before
$image->save('out.jxl', quality: $settings['img_quality']); // config says 120

// after
$image->save('out.jxl', quality: (int) clamp((int) $settings['img_quality'], 0, 100));
Defensive patterns

Strategy: validation

Validate before calling

$quality = max(0, min(100, (int) $quality));
$image->save('out.jxl', quality: $quality);

Type guard

function isValidQuality(mixed $quality): bool
{
    return is_int($quality) && $quality >= 0 && $quality <= 100;
}

Prevention

When it happens

Trigger: new JxlEncoder(quality: 110), new JxlEncoder(-1), or $image->encodeUsingPath('photo.jxl', quality: $value) with the value outside 0-100.

Common situations: Unvalidated quality from client requests or stored settings; scaled percentages exceeding 100; porting code from libraries that accept quality above 100 or a 0-1 float scale.
