Pango.log2vis_get_embedding_levels
Description: Reference for Pango.log2vis_get_embedding_levels

### 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.
