From: Matt Huszagh <huszaghmatt <at> gmail.com> To: bug-gnu-emacs <at> gnu.org Subject: 28.0.50; shr displays inline images on new line Date: Sun, 10 Oct 2021 10:50:52 -0700
shr appears to display all images on their own line, irrespective of
whether they are intended to be inline. An example of this can be seen
at https://en.wikipedia.org/wiki/Chain_rule:
(eww "https://en.wikipedia.org/wiki/Chain_rule")
For example, the equation showing h as the composition of f and g is
displayed on its own line, but should be displayed in line with the
surrounding text (as confirmed by viewing the page in a GUI-based
browser such as Firefox).
I took a quick look at the shr source code but couldn't determine why
this was actually happening. In particular, I couldn't find anything
in the shr-put-image function that might cause this. Using the above
example, the text that is overlayed with the image is
"{\\displaystyle h=f\\circ g}"
The insert-image function documentation indicates that the image
should be displayed at the location of that text. I additionally
tested this by downloading the SVG image file and using some simple
elisp code:
cd /tmp
wget https://wikimedia.org/api/rest_v1/media/math/render/svg/a14345f3938c66b1fde08e18d8b301a59c5775a5
(let ((data (with-temp-buffer
(insert-file-contents "/tmp/img/a14345f3938c66b1fde08e18d8b301a59c5775a5")
(buffer-string))))
(with-current-buffer (get-buffer-create "*test*")
(insert "some text ")
(insert-image (create-image data 'svg t :ascent 100) "{\\displaystyle h=f\\circ g}")))
The image displays inline as expected.
Why is shr displaying the image on its own line? How can I remedy
this?
Thanks!
Matt
