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
.
