NAME

       fribidi_get_par_direction - get base paragraph direction

SYNOPSIS

       #include <fribidi.h>

       FriBidiParType fribidi_get_par_direction
       (
	    const FriBidiCharType *bidi_types,
	    const FriBidiStrIndex len
       );

PARAMETERS

       const FriBidiCharType *bidi_types
	      Input list of bidi types as returned by fribidi_get_bidi_types().

	      Possible values for a const FriBidiCharType are as follows:
	      FRIBIDI_TYPE_LTR	Left-To-Right letter.
	      FRIBIDI_TYPE_RTL	Right-To-Left letter.
	      FRIBIDI_TYPE_AL	Arabic Letter.
	      FRIBIDI_TYPE_EN	European Numeral.
	      FRIBIDI_TYPE_AN	Arabic Numeral.
	      FRIBIDI_TYPE_ES	European number Separator.
	      FRIBIDI_TYPE_ET	European number Terminator.
	      FRIBIDI_TYPE_CS	Common Separator.
	      FRIBIDI_TYPE_NSM	Non Spacing Mark.
	      FRIBIDI_TYPE_BN	Boundary Neutral.
	      FRIBIDI_TYPE_BS	Block Separator.
	      FRIBIDI_TYPE_SS	Segment Separator.
	      FRIBIDI_TYPE_WS	WhiteSpace.
	      FRIBIDI_TYPE_ON	Other Neutral.
	      FRIBIDI_TYPE_LRE	Left-to-Right Embedding.
	      FRIBIDI_TYPE_RLE	Right-to-Left Embedding.
	      FRIBIDI_TYPE_LRO	Left-to-Right Override.
	      FRIBIDI_TYPE_RLO	Right-to-Left Override.
	      FRIBIDI_TYPE_PDF	Pop Directional Flag.

       const FriBidiStrIndex len
	      Input string length.

DESCRIPTION

       This  function  finds  the  base direction of a single paragraph, as defined by rule P2 of the Unicode Bidirectional Algorithm available at
       http://www.unicode.org/reports/tr9/#P2.

       You typically do not need this function as fribidi_get_par_embedding_levels() knows how to compute base direction itself, but you may  need
       this to implement a more sophisticated paragraph direction handling.  Note that you can pass more than a paragraph to this function and the
       direction of the first non-neutral paragraph is returned, which is a very good heuristic to set direction of the neutral paragraphs at  the
       beginning of text.  For other neutral paragraphs, you better use the direction of the previous paragraph.

RETURNS

       Base pargraph direction.  No weak paragraph direction is returned, only LTR, RTL, or ON.

       Possible values for a FriBidiParType are as follows:
	      FRIBIDI_PAR_LTR	Left-To-Right paragraph.
	      FRIBIDI_PAR_RTL	Right-To-Left paragraph.
	      FRIBIDI_PAR_ON	DirectiOn-Neutral paragraph.
	      FRIBIDI_PAR_WLTR	Weak Left To Right paragraph.
	      FRIBIDI_PAR_WRTL	Weak Right To Left paragraph.
