Thanks,
I can confirm that running (clear-image-cache) removes them from the X
server.
However I can't see that it is done every 100 redisplays. If it were I
would expect the code below to never create more than 100 (+ the ones
that were there before it started) pixmaps in X11. Letting it run while
writing this mail it now has reached above 3000 pixmaps according to
xrestop.
(defun aw-svg-image-test-update (buf)
(interactive)
(with-current-buffer buf
(erase-buffer)
(insert-image (create-image (format "<svg width=\"50\"
height=\"50\"><rect x=\"0\" y=\"0\" width=\"100\" height=\"100\"
fill=\"#%02x%02x%02x\"/></svg>" (random 255)(random 255)(random 255))
'svg t))))
(defun aw-svg-image-test-kill-buffer-hook ()
(cancel-timer aw-svg-image-test-timer))
(defun aw-svg-image-test ()
(interactive)
(with-current-buffer (generate-new-buffer "*aw-svg-image-test*")
(display-buffer (current-buffer))
(make-local-variable 'aw-svg-image-test-timer)
(add-hook 'kill-buffer-hook 'aw-svg-image-test-kill-buffer-hook nil t)
(setq aw-svg-image-test-timer (run-at-time nil 0.2
'aw-svg-image-test-update (current-buffer)))))
