PgMiscellaneous.log2visGetEmbeddingLevels

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.

log2visGetEmbeddingLevels

Parameters

text string

the text to itemize.

length int

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

pbaseDir PangoDirection*

input base direction, and output resolved direction.

Return Value

Type: ubyte*

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