Detailed Description

Performs SVG cropping by applying a wrapper SVG as view

A simple SVG with an input like this:

<svg version="1.1" xmlns="http://www.w3.org/2000/svg" x="0" y="0" viewBox="0 168.4 940.7 724" width="941" height="724"> <path id="path" d="M490.1 655.5c-9.4 1.2-16.9 </svg>

is wrapped with crop dimensions (i.e. "50 50 640 480") to something like this:

<svg version="1.1" xmlns="http://www.w3.org/2000/svg" viewBox="50 50 640 480" width="640" height="480"> <svg version="1.1" xmlns="http://www.w3.org/2000/svg" x="0" y="0" viewBox="0 168.4 940.7 724" width="941" height="724"> <path id="path" d="M490.1 655.5c-9.4 1.2-16.9 </svg> </svg>

adjustSvgDimensions()

TYPO3\CMS\Core\Imaging\SvgManipulation::adjustSvgDimensions ( \DOMDocument  $originalSvg, array  $determinedDimensions  )

protected

Ensure that the determined width and height settings are attributes on the original <svg>. If those were missing, cropping could not successfully be applied when getting embedded and adjusted within a element.

Returns true, if the determined width/height has been injected into the main <svg>
