I like the idea of inline image display too, but hit the similar
problems.  After reading the code in org.el, I found that the inline
image file link has to start with either "file:" or "./".

For example, the following two links are OK:

   [[file:~/images/myImage.png]]
   [[./figures/org-mode-unicorn.svg]]

but the following two are not:

   [[Screenshot.png]]
   [[~/images/myImage.png]]

Here is a small patch that seems to work well for me, but I'd like
Carsten to check whether it may break anything:

This one I do not want to support, because it limits what other things  
we
can do with links.

>   [[~/images/myImage.png]]

This one on the other hand should be supported, I like that.  Can you  
please modify the patch accordingly?  I believe this will also require  
corresponding changes in the exporter(s) somewhere...

Thanks!

OK, I modified the patch a little bit and came up with a version (see
below) that can handle the following 7 cases.  Please check if it looks
good to you.  I don't see any needed exporter changes so far...

Hi Baoqiu,

thanks for the patch, I have applied it.  Hopefully this will work in  
the
export backends, but it might - otherwise we will see bug reports soon  
enough...

Thanks, Carsten.  I have tried my test case for LaTeX, DocBook, and HTML
exporters and everything seemed to work.

Wow -- adding images to an org file

[Nathan Neff]

I just saw Andreas's screenshot here:

http://orgmode.org/worg/org-screenshots.php

If you zoom in to his screenshot,
http://orgmode.org/img/screenshots/org_andreas.jpg

You can see how he adds images to his org files.
All that I had to do was put this into my emacs init file:

(defun org-dblock-write:image (params)
  (let ((file (plist-get params :file)))
     (clear-image-cache file)
     (insert-image (create-image file) )))

Then, put this in an org-file:

#+BEGIN: image :file "~/Documents/personal/foo.png"
#+END

And run C-c C-c (or is it C-c C-x C-u)?

Anyway, Cool stuff!

Another way to have images in org-mode documents is to use the "iimage"
minor mode, which handles  inline images:
http://www.netlaputa.ne.jp/~kose/Emacs/iimage.html

For additional documentation:
http://orgmode.org/worg/org-configs/org-config-examples.php#sec-2_2

It's pretty nifty.

At that place, I find this code:
(add-to-list 'iimage-mode-image-regex-alist (cons (concat "\\[\\[file:\ 
\(~?" iimage-mode-image-filename-regex "\\)\\]") 1))
  (defun org-toggle-iimage-in-org () "display images in your org  
file" (interactive) (if (face-underline-p 'org-link) (set-face- 
underline-p 'org-link nil) (set-face-underline-p 'org-link t)) (iimage- 
mode))
I guess I could actually add the above code to org.el, so that the  
only thing to do for a user would be to turn on iimage-mode.
What is the purpose of toggling the underline property of the link face?

It puts a horizontal line through the middle of the displayed image
(haven't checked if that's fixed in latest emacs).

I see.

We have now native inline image display in Org-mode, you can toggle it  
with

C-c C-x C-v

This implementation uses overlays instead of text properties and  
therefore does not interfere with font-lock.

In short

What I have to do (minimal code in .emacs and .org) to display an image?


This image will be maintained when I export the file?

iimage could be included in org distribution?

Update to current Org-Mode and from the on press


    C-c C-x C-v

Yes.

Not neccessary anymore.

I'm using Org-Babel and R, and when I use C-c C-c to update the output
from a block of code, the image in emacs doesn't change.

Ideas? v6.36

Thanks.

Hi Russell,

I struggled with this when images were text properties, i.e. before
Carsten's implementation using overlays (thanks for C-c C-x C-v
Carsten!)

I think the answer may be clear-image-cache. I just tried that and C-c
C-x C-v showed the new image afterwards. I'm not sure whether the
following is acceptable in terms of emacs ecology, but it seems to do
the trick:

--8<---------------cut here---------------start------------->8---
diff --git a/lisp/org.el b/lisp/org.el
index c52aeb0..85f1219 100644
--- a/lisp/org.el
+++ b/lisp/org.el
@@ -15507,6 +15507,7 @@ with a description part will be inlined."
   "Remove inline display of images."
   (interactive)
   (mapc 'delete-overlay org-inline-image-overlays)
+  (clear-image-cache)
   (setq org-inline-image-overlays nil))
--8<---------------cut here---------------end--------------->8---

Note also that we can make image display happen automatically after
executing a babel block:

(add-hook 'org-babel-after-execute-hook 'org-display-inline-images)

In fact that was what I had in mind when adding that hook; it was just
waiting for Carsten's function. So in my mind this gets us some of the
way towards org-babel as an "interactive notebook", as discussed in
another recent thread.

Dan

p.s. For what its worth, here is the code I was using to make images
appear using text properties and Org font lock. I was intending to post
this when I was happy with the image refresh stuff, but it is probably
redundant in light of the new functions using overlays. A certain amount
of messing about with image redisplay and cache functions is evident.

--8<---------------cut here---------------start------------->8---
(defun dan/org-fontify-image-links (limit)
  "Display links to images as images.
If the description part of the link is empty display the image,
otherwise do nothing. This function is intended to be called
during font-lock fontification."
  (let ((case-fold-search t) file image)
    (and dan/org-display-inline-images
         (re-search-forward
          (concat "\\[\\[file:\\(" iimage-mode-image-filename-regex "\\)\\]\\]") limit t)
         (setq file (match-string 1))
         (setq file (iimage-locate-file file (list default-directory)))
         (setq image (create-image file))
         (add-text-properties (match-beginning 0) (match-end 0) (list 'display image))
         ;; (clear-image-cache)
         (image-refresh image)
         ;; (redisplay)
         ;; (redraw-frame)
         ;; (redraw-display)
         ;; (image-refresh image)
         )))

(setq dan/org-display-inline-images t)
(add-hook 'org-font-lock-hook 'dan/org-fontify-image-links)
--8<---------------cut here---------------end--------------->8---

Yes, when you change an image on the disk, you need to clear the cache
to make sure it is not being pulled out of the cache.  image-refresh  
will
just clear the cache for an individual image, and make it redisplay in  
his way.

I have applied you patch, but I am clearing the cache before  
displaying the new images.  When removing the org images, it is  
possible that the image cache still contains other images.

I have also added new arguments to org-display-inline-images which  
will allow you
to call it in a way hat it refreshes existing images without clearing  
the entire cache.  Maybe you can do that in order to update after  
babel operations?

I did not know you were working on this, sorry for stepping on your  
toes here.
Let me know if you think we should go back to text properties and font- 
lock.
