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.
