Crop feature for srcset pictures. Without this patch the srcset images are not rendered when a crop variable is set.

Crop feature for srcset pictures. Without this patch the srcset images are not rendered when a crop variable is set.
Division by zero check when calculating ratio
Wrap can be ignored when $treatIdAsReference=TRUE
Height calculation can be ignored when height attribute is missing

When $treatIdAsReference = FALSE the generation of the srcset images does not work. There is a problem when processed images are getting processed again.

If $treatIdAsReference = TRUE the srcset images are getting processed from the original image. Therefore the crop and ratio information is needed.
When setting the quality attribute MathUtility was not found

add use TYPO3\CMS\Core\Utility\MathUtility;

$width = $width . $dimensions['postWidth'];
$srcsetVariant = $this->getImgResource($src, $width, $height, $format, $quality, $treatIdAsReference, $crop);

Yes, I know that's super picky, but could you transform the call to a multi-line one? The code style still fails on checking it.

$this->getImgResource(
  $src, 
  $width, 
  $height,
  $format, 
  $quality, 
  $treatIdAsReference, 
  $crop
);

Thank you. I enabled it.

$treatIdAsReference = (boolean) $this->arguments['treatIdAsReference'];
if (true === $treatIdAsReference) {
$src = $this->arguments['src'];
$crop = $this->arguments['crop'];
if ($crop === null) {
$crop = $src instanceof FileReference ? $src->getProperty('crop') : null;

getImgResource signature change is potentially breaking for other ViewHelpers using the trait - may not be exposed by unit tests either!
