◆ fileIsSource()

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

◆ getDescLinkAttribs()

MediaTransformOutput::getDescLinkAttribs	(		$title = null,
			$params = [] )

Parameters

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

Returns: array

MediaTransformOutput::getFile ( )

Returns: File

Definition at line 83 of file MediaTransformOutput.php.

◆ getHeight()

MediaTransformOutput::getHeight ( )

Returns: int Height of the output box

Definition at line 76 of file MediaTransformOutput.php.

◆ getLocalCopyPath()

MediaTransformOutput::getLocalCopyPath ( )

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

Callers should never write to this path.

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

Returns: bool

◆ isError()

MediaTransformOutput::isError ( )

This will be overridden to return true in error classes.

Returns: bool
