fribidi_log2vis(3)	      Programmer's Manual	    fribidi_log2vis(3)

NAME
       fribidi_log2vis - get visual string

SYNOPSIS
       #include <fribidi.h>

       FriBidiLevel fribidi_log2vis
       (
	    const FriBidiChar *str,
	    const FriBidiStrIndex len,
	    FriBidiParType *pbase_dir,
	    FriBidiChar *visual_str,
	    FriBidiStrIndex *positions_L_to_V,
	    FriBidiStrIndex *positions_V_to_L,
	    FriBidiLevel *embedding_levels
       );

PARAMETERS
       const FriBidiChar *str
	      Input logical string.

       const FriBidiStrIndex len
	      Input string length.

       FriBidiParType *pbase_dir
	      Requested and resolved paragraph base direction.

	      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.

       FriBidiChar *visual_str
	      Output visual string.

       FriBidiStrIndex *positions_L_to_V
	      Output mapping from logical to visual string positions.

       FriBidiStrIndex *positions_V_to_L
	      Output  mapping  from  visual  string back to the logical string
	      positions.

       FriBidiLevel *embedding_levels
	      Output list of embedding levels.

DESCRIPTION
       This function converts the logical input string to  the	visual	output
       strings as specified by the Unicode Bidirectional Algorithm.  As a side
       effect it also generates mapping lists between the two strings, and the
       list of embedding levels as defined by the algorithm.

       If  NULL is passed as any of the the lists, the list is ignored and not
       filled.

       This function is obsolete because it only handles one-line  paragraphs.
       Please consider using other functions instead.  Deprecated.

RETURNS
       Maximum	level  found  plus  one,  or zero if any error occured (memory
       allocation failure most probably).
