And this is now implemented, documented and pushed. Feel free to tweak
the logic. :-)
This defaults to 'auto, which means that it uses the dubious heuristic
"a character on a 'normal' screen is 10 pixels wide".
(defun image-compute-scaling-factor (scaling)
(cond
((numberp image-scaling-factor)
image-scaling-factor)
((eq image-scaling-factor 'auto)
(let ((width (/ (float (window-width nil t)) (window-width))))
;; If we assume that a typical character is 10 pixels in width,
;; then we should scale all images according to how wide they
;; are. But don't scale images down.
(if (< width 10)
1
(/ (float width) 10))))
(t
(error "Invalid scaling factor %s" image-scaling-factor))))
I don't have any statistics to back that up, though. Anybody have any
feelings on the "10" thing?
