NAME

       fribidi_log2vis - get visual string

SYNOPSIS

       #include <fribidi.h>

       extern 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       This  function  is  obsolete because it only handles one-line paragraphs.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  occurred  (memory  allocation  failure
       most probably).
