NAME

       mdraw_text_per_char_extents -

SYNOPSIS

       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 * overall_logical_return)

DESCRIPTION

       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 num_chars_return.

       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.
