mdraw_text_per_char_extents(3m17nVersion 1.5mdraw_text_per_char_extents(3m17n)

       mdraw_text_per_char_extents - Compute the text dimensions of each
       character of M-text.

       int mdraw_text_per_char_extents (MFrame * frame,	MText *	mt, int	from,
       int to, MDrawControl * control, MDrawMetric * ink_array_return,
       MDrawMetric * logical_array_return, int array_size, int *
       num_chars_return, MDrawMetric * overall_ink_return, MDrawMetric *

       Compute the text	dimensions of each character of	M-text.

       The mdraw_text_per_char_extents() function computes the drawn metric of
       each character between from and to of M-text mt assuming	that they are
       drawn on	a window of frame frame	using the mdraw_text_with_control()
       function	with the drawing control object	control.

       array_size specifies the	size of	ink_array_return and
       logical_array_return.  Each successive element of ink_array_return and
       logical_array_return are	set to the drawn ink and logical metrics of
       successive characters respectively, relative to the drawing origin of
       the M-text. The number of elements of ink_array_return and
       logical_array_return that have been set is returned to

       If array_size is	too small to return all	metrics, the function returns
       -1 and store the	requested size in num_chars_return.  Otherwise,	it
       returns zero.

       If pointer overall_ink_return and overall_logical_return	are not	NULL,
       this function also computes the metrics of the overall text and stores
       the results in the members of the structure pointed to by
       overall_ink_return and overall_logical_return.

       If control->two_dimensional is nonzero, this function computes only the
       metrics of characters in	the first line.
