Function
Pangoshape
Declaration [src]
void
pango_shape (
const char* text,
int length,
const PangoAnalysis* analysis,
PangoGlyphString* glyphs
)
Description [src]
Convert the characters in text
into glyphs.
Given a segment of text and the corresponding PangoAnalysis
structure
returned from pango_itemize()
, convert the characters into glyphs. You
may also pass in only a substring of the item from pango_itemize()
.
It is recommended that you use pango_shape_full()
instead, since
that API allows for shaping interaction happening across text item boundaries.
Some aspects of hyphen insertion and text transformation (in particular,
capitalization) require log attrs, and thus can only be handled by
pango_shape_item()
.
Note that the extra attributes in the analyis
that is returned from
pango_itemize()
have indices that are relative to the entire paragraph,
so you need to subtract the item offset from their indices before
calling pango_shape()
.
