mdraw_per_char_extents(3m17n)

NAME
mdraw_per_char_extents - Obtain per character dimension information.

SYNOPSIS
void mdraw_per_char_extents (MFrame * frame, MText * mt, MDrawMetric * array_return, MDrawMetric * overall_return)

DESCRIPTION
Obtain per character dimension information.

The mdraw_per_char_extents() function computes the text dimension of each character in M-text mt. The faces given as text properties in mt and the default face of frame frame determine the fonts to draw the text. Each successive element in array_return is set to the drawn metrics of successive characters, which is relative to the origin of the drawing, and a rectangle for each character in mt. The number of elements of array_return must be equal to or greater than the number of characters in mt.

If pointer overall_return is not NULL, this function also computes the extents of the overall text and stores the results in the members of the structure pointed to by overall_return.
