Can I scroll inline images horizontally?

Can I scroll inline images horizontally?

[Felix E. Klee]

Hi,

I use imaxima-mode to interface with the computer algebra system Maxima. This mode renders formulas as inline images. However, often the images are too wide to find in the emacs buffer. Therefore I would like to scroll them horizontally. But scroll-left and scroll-right only work if there is also a long line of text. So in order to view these formulas, I first have to create a long line of text and then I can use scroll-left and scroll-right.

Is there some way to tell EMACS that I want to scroll horizontally even if there aren't any long lines of text?

In a way, there is.  You have to implement the feature.  Many people
will be happy if you do.  (Displaying tall images also needs work.)

Perhaps this deserves more looking into.  I have buffers that contain
nothing but a jpeg image, and I can scroll them horizontally using
(scroll-left) and (scroll-right).

I insert an image into the current buffer using:
     (insert-image (create-image "rms.jpeg") (point))

I scroll them vertically using:
     (set-window-vscroll nil (+ (window-vscroll) .5))))
and
     (set-window-vscroll nil (- (window-vscroll) .5))))
