* Change appearance of selected image

Hello,

I'm getting more and more used to view photos in Emacs. I now have a
buffer with thumbnails and when I move in that buffer the image is
selected as expected. However, the selected image is hardly visible as
being selected. A thin dark rectangle is drawn around it. How can I
change that? And how can I make Emacs draw/display another rectangle
around an image, so it may appear as “marked”?

Thanks! and kind regards
Eike

I guess you are speaking of `image-dired'?

You should be able to find that as a user option.  Try to browse options
with

   M-x customize-group image-dired RET

Seems this is not implemented (yet).  A feature request (M-x
report-emacs-bug) might be appropriate.  But it might be the case that
this was not implemented by intent.


Regards,

Michael

Hello Michael,

thank you for your reply!

Sorry, I was not precise: I'm using `(insert-image (create-image
…))'.

I didn't really think of image-dired, but I can probably make use of it,
it looks quite feature-rich. 


Kind regards

Looking at the code, there seems to be no way to change the width of the
box that's drawn around images (when the cursor is on them).  You can,
however, change the colour.  I use a red cursor myself:

(setq default-frame-alist
      (nconc (list '(mouse-color . "red")
		    '(cursor-type . box)
		    '(cursor-color . "red"))
	     default-frame-alist))

Hm...  I don't think Emacs has any built-in functionality for doing
that.  I think you'd have to create a new image that has the border you
want, and then composite the thumbnail onto it.

Then (I'm cusious), why it useful to change how the image is drawn when
it is "marked" (do you mean that it is part of an active region)?

I was thinking of making a function that marks an image to be able to do
some actions with the selection, like copying, deleting etc. (what I can
do in dired). Working with photos from cameras in dired is not so easy
otherwise.

Kind regards
Eike

Well, this indeed matches image-dired quite well, I think.  You can mark
images in image dired, but I think you get no visual feedback.

But the cool thing is that the image-dired is connected with a standard
dired buffer (where the marks then appear and you can do all things one
can do from within dired).  Just try it.


Michael.

Thanks!! That is really helpful. And its good enough for me to recognize
selected images. The only side effect is that the normal cursor is red,
too :) but, that's ok for me.

Yes, I was thinking about that, too. But I was hoping that I just missed
some vars to set :)

Thank you! and kind regards

That sounds indeed like what I want (except the visual feedback).  I'll
look into it. Thank you!
