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 data is owned by the caller of the function.

Return value

Type: 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.
