representing text before split_index, which should be freed with [pango.glyph_item.GlyphItem.free].
GlyphItem.split
pango.glyph_item.GlyphItem split(string text, int splitIndex)Modifies orig to cover only the text after split_index, and returns a new item that covers the text before split_index that used to be in orig.
You can think of split_index as the length of the returned item. split_index may not be 0, and it may not be greater than or equal to the length of orig (that is, there must be at least one byte assigned to each item, you can't create a zero-length item).
This function is similar in function to [pango.item.Item.split] (and uses it internally.)
Parameters
text | text to which positions in orig apply |
splitIndex | byte index of position to split item, relative to the start of the item |
Returns
the newly allocated item
