save rotated image in image-mode

save rotated image in image-mode

[Peter Münster]

Hi,

I would like to rotate an image by 90° and save the result. How could I
do this please?

It seems, that "i r" and "s r" change only the display...

TIA for any hints,

Hi,

I don't know if you can do that in image-mode… but you can in
image-dired-mode.  Here is the recipe:

            - Open the image directory in dired
            - Mark the image file with 'm'
            - 'C-t d' (image-dired-display-thumbs)
            - Then type 'R' to rotate 90° clockwise or 'L' for counter
              clockwise
              
Emacs will ask if you want to erase the original file with the
transformed one.

Sorry, I should have mentioned, that I know about this possibility.
The question is really about image-mode, without using image-dired-mode.

It seems, that this is not implemented. Should it? Would it make sense
to send a feature request?

Maybe someone more knowledgeable will chime in but I also don't think it
is implemented.  It could be a good idea to have it in image-mode and
maybe you could code it yourself, no?
