function ImageStyle::addExtension

Adds an extension to a path.

If this image style changes the extension of the derivative, this method adds the new extension to the given path. This way we avoid filename clashes while still allowing us to find the source image.

Parameters

string $path: The path to add the extension to.

Return value

string The given path if this image style doesn't change its extension, or the path with the added extension if it does.
