Function pango::shape

pub fn shape(text: &str, analysis: &Analysis, glyphs: &mut GlyphString)
Expand description

Convert the characters in @text into glyphs.

Given a segment of text and the corresponding Analysis structure returned from itemize(), convert the characters into glyphs. You may also pass in only a substring of the item from itemize().

It is recommended that you use 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 shape_item().

Note that the extra attributes in the @analyis that is returned from itemize() have indices that are relative to the entire paragraph, so you need to subtract the item offset from their indices before calling shape().
