Function

Pangolog2vis_get_embedding_levels

Declaration [src]

guint8*
pango_log2vis_get_embedding_levels (
  const gchar* text,
  int length,
  PangoDirection* pbase_dir
)

Description [src]

Return the bidirectional embedding levels of the input paragraph.

The bidirectional embedding levels are defined by the Unicode Bidirectional Algorithm available at:

http://www.unicode.org/reports/tr9/

If the input base direction is a weak direction, the direction of the characters in the text will determine the final resolved direction.

Available since:1.4

Parameters

text const gchar*
 

The text to itemize.

 The data is owned by the caller of the function.
 The string is a NUL terminated UTF-8 string.
length int
 

The number of bytes (not characters) to process, or -1 if text is nul-terminated and the length should be calculated.

pbase_dir PangoDirection
 

Input base direction, and output resolved direction.

 The data is owned by the caller of the function.

Return value

Returns: guint8*
 

A newly allocated array of embedding levels, one item per character (not byte), that should be freed using g_free().

 The data is owned by the called function.
