Member Function Documentation

MediaTransformOutput::fileIsSource ( )

Check if the output thumbnail is the same as the source.

This can occur if the requested width was bigger than the source.

Returns: bool

		$params = `[]`
	)

Parameters

string	$title
string \| array	$params	Query parameters to add

Returns: array

MediaTransformOutput::getLocalCopyPath ( )

Get the path of a file system copy of the thumbnail.

Callers should never write to this path.

Returns: string|bool Returns false if there isn't one
