Hi all,
I'm trying to measure strings in an Emacs buffer. The current code is yielding
surprising results:
(progn
(save-excursion
(insert #("s " 1 2 (display (space :width (50))))))
(window-text-pixel-size nil (point) (1+ (point))))
On my machine a single 's' is 8 pixels wide, but this snippet returns 58.
The following snippet, however, returns 8 as expected:
(progn
(save-excursion
(insert "s "))
(window-text-pixel-size nil (point) (1+ (point))))
It seems that adding a display property on the space changes the return value
of window-text-pixel-size; is that expected?
Thanks,
Clément.
