I replaced step 5 with step 6 by extracting the logic code of
org-link-beautify, but I found it does not have center-line. That's
really weird.
1. =$ emacs -Q=
2. install package =[M-x package-install RET org-link-beautify RET]=
3. load the package =[M-x load-library org-link-beautify RET]=
4. open an Org file which has content which has a "file:" link to a video file (You can replace
the video file link as yours) :
#+begin_src org
,* headline 1
link [[file:~/Downloads/3veEPJrQrV1EtpH9.mp4]]
#+end_src
5. enable minor mode =[M-x org-link-beautify-mode RET]=. This mode will auto thumbnail for video
file and display it with /text-property/.
6. reproduce without org-link-beautify
#+begin_src emacs-lisp
(let ((start (point))
(end (save-excursion (forward-word) (point))))
(org-link-beautify--add-overlay-marker start end)
(put-text-property
start end
'display (create-image "~/Downloads/.thumbnails/3veEPJrQrV1EtpH9.png" nil nil :ascent 'center :max-height 512))
(make-local-variable 'image-map)
(define-key image-map (kbd "<mouse-1>") 'org-open-at-point))
#+end_src
7. The displayed thumbnail on link has a center-line.
8. But open the generated thumbnail image file =file:.thumbnails/3veEPJrQrV1EtpH9.png= with external
program, it does not have this center-line.
