Use
The isNewlineBeforeImage method specifies whether or not a line break is inserted automatically before an <img> tag.
If you want graphics to start in a new line, you must use the <br/> tag in devices that return the value false. In mobile devices that meet this condition, this could result in the insertion of a blank line, which you want to avoid due to space restrictions on small screens.
The same arguments for the use of this method apply to all methods that concern line breaks into new lines.
