does create-image caches??

does create-image caches??

[Xah Lee]

i have this function which returns the image file's width and height
as a list, of a given image file path.

(defun get-image-dimensions2 (img-file-relative-path)
  "Returns a image file's width and height as a list."
  (let (tmp dimen)
    (setq tmp
          (create-image (concat default-directory img-file-relative-
path)))
    (setq dimen (image-size tmp t))
    (list (car dimen) (cdr dimen))
  )
)

My problem with this is that, suppose i have a image x.png. Now, i run
this function to get its dimensions. Now, i crop x.png so its
dimension is changed. But when i run this function again, the
dimension doesn't change.

Seems emacs somehow has cached size of previous tmp img. How to fix
this?

Thanks.

Try `clear-image-cache'.
