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().
