I am trying to open images in image-mode and apply some modifications and finally save the image with image-save. Please refer here: https://www.gnu.org/software/emacs/manual/html_node/elisp/Showing-Images.html

Something strange happens that some times buffer reverts to the original image! But most commonly, I have the buffer to an image, but image is saved untransformed!

So, what's going wrong here?!

  • So, as an example, you are opening e.g. a PNG file, rotating it 90 degrees and then you try to save the rotated image to a file - is that correct? – NickD Jul 08 '21 at 02:25
