Function

Pangoshape_item

Declaration [src]

void
pango_shape_item (
  PangoItem* item,
  const char* paragraph_text,
  int paragraph_length,
  PangoLogAttr* log_attrs,
  PangoGlyphString* glyphs,
  PangoShapeFlags flags
)

Description [src]

Convert the characters in item into glyphs.

This is similar to pango_shape_with_flags(), except it takes a PangoItem instead of separate item_text and analysis arguments. It also takes log_attrs, which may be used in implementing text transforms.

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 do not pass the full paragraph text as paragraph_text, you need to subtract the item offset from their indices before calling pango_shape_with_flags().
