Which means I can use this:
(defun window-height-pixels ()
(let ((line-pixel-height-ratio (/ (+ (frame-pixel-height) 0.0) (frame-height)))
(column-pixel-width-ratio (/ (+ (frame-pixel-width) 0.0) (frame-width))))
(ftruncate (* (window-height) line-pixel-height-ratio))))
(defun window-width-pixels ()
(let ((column-pixel-width-ratio (/ (+ (frame-pixel-width) 0.0) (frame-width))))
(ftruncate (* (window-width) column-pixel-width-ratio))))
I see that the frame-pixel-functions is including window
decorations and stuff, but I guess it can work for my
purposes anyway.
Thanks!
