Member Function Documentation

applyCropping()

TYPO3\CMS\Core\Resource\Processing\SvgImageProcessor::applyCropping ( TaskInterface  $task, Area  $cropArea, ImageDimension  $imageDimension  )

protected

Create standalone wrapper files for SVGs. Cropped responsive images delivered via an tag or as a URI for a background image, need to be self-contained. Therefore we wrap a <svg> container around the original SVG content. A viewBox() crop is then applied to that container. The processed file will contain all the viewBox cropping information and thus transports intrinsic sizes for all variants of CSS processing (max/min width/height).
