shape
Convert the characters in @text into glyphs.
Given a segment of text and the corresponding PangoAnalysis
structure returned from func@Pango.itemize, convert the characters into glyphs. You may also pass in only a substring of the item from func@Pango.itemize.
It is recommended that you use func@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 func@Pango.shape_item.
Note that the extra attributes in the @analyis that is returned from func@Pango.itemize have indices that are relative to the entire paragraph, so you need to subtract the item offset from their indices before calling func@Pango.shape.
Parameters
the text to process
the length (in bytes) of @text
PangoAnalysis
structure from func@Pango.itemize
glyph string in which to store results
