Subject: bug#54862: 28.1; window-text-pixel-size sometimes fails to report accurate pixel-width
Date: Mon, 11 Apr 2022 20:48:03 +0200 [thread overview]
Message-ID: <m2h76za23g.fsf@metalevel.at> (raw)
To reproduce this regression, please invoke Emacs with:
$ emacs -Q
and then evaluate the following form:
(let ((width 20))
(= width (let* ((height (line-pixel-height))
(data (with-temp-buffer
(insert (format "P1\n%s %s\n" width height))
(dotimes (_ height)
(insert (make-string width ?1) "\n"))
(buffer-string))))
(insert " ")
(let ((from (point)))
(insert-image `(image :type pbm :data ,data :ascent center) "t")
(car (window-text-pixel-size nil from (point)))))))
The expected result, obtained for example in Emacs 26.1 and 27.1, is: t.
Whereas with Emacs 28.1, evaluating the form unexpectedly yields: nil.
If possible, could you please restore the previous behaviour?
Thank you and all the best,
Markus
