Description: Reference for Pango.log2vis_get_embedding_levels

### Function

# Pangolog2vis_get_embedding_levels

since: 1.4

#### 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.

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`

  Type: `const gchar*`

  The text to itemize.

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

`length`

  Type: `int`

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

`pbase_dir`

  Type: `PangoDirection`

  Input base direction, and output resolved direction.

  The argument will be modified by the function.
  The caller of the function takes ownership of the returned data, and is responsible for freeing it.

#### Return value

Type: An array of `guint8`

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

The caller of the function takes ownership of the data, and is responsible for freeing it.
