index_to_pos


Description:

public Rectangle index_to_pos (int index_)

Converts from an index within a Layout to the onscreen position corresponding to the grapheme at that index, which is represented as rectangle.

Note that pos->x is always the leading edge of the grapheme and pos->x + pos->width the trailing edge of the grapheme. If the directionality of the grapheme is right-to-left, then pos->width will be negative.

Parameters:

pos
