private float firstLineRealHeight ( ) { float firstLineRealHeight = 0f ; if ( firstLine != null ) { PdfChunk chunk = firstLine . getChunk ( 0 ) ; if ( chunk != null ) { Image image = chunk . getImage ( ) ; if ( image != null ) { firstLineRealHeight = firstLine . getChunk ( 0 ) . getImage ( ) . getScaledHeight ( ) ; } else { firstLineRealHeight = useAscender ? firstLine . getAscender ( ) : leading ; } } } return firstLineRealHeight ; }
Calculates what the height of the first line should be so that the content will be flush with the top . For text this is the height of the ascender . For an image it is the actual height of the image .
