From the package imagex, I use the function imagex-sticky-maximize to maximize the image files to the current window.
This works like a charm on Windows 7 x64 with Emacs 25.0.50 However, with the same Emacs setup, I'm trying out Linux Ubuntu. I use the latest Emacs snapshot:
GNU Emacs 25.0.50.2 (x86_64-pc-linux-gnu, GTK+ Version 3.16.7) of 2015-10-28
Everything in Emacs works, except the function imagex-sticky-maximize. Then I get the error when I want to maximize the image:
image+: (file-error Searching for program No such file or directory convert)
I see the pictures (JPEG, PNG, everything) in Emacs buffer. So image display works.
When I look in the source code of imagex-sticky-maximize in order to understand why this problem arises on Linux, and not on Windows:
(defun imagex-sticky-maximize ()
"Maximize the point image to fit the current frame."
(interactive)
(imagex-sticky--convert-image
(lambda (image)
(imagex--maximize image))))
Given the error message, seems the imagex-sticky--convert-image could be the culprit. Looking further in the source:
(defun imagex-sticky--convert-image (converter)
(catch 'done
(let (err)
(condition-case err1
(let ((display (imagex-sticky--current-ovprop-display)))
(when display
(cl-destructuring-bind (image ov) display
(let ((new (funcall converter image)))
(plist-put (cdr new) 'imagex-manual-manipulation t)
(overlay-put ov 'display new))
(throw 'done t))))
(error
(setq err (append err err1))))
(condition-case err2
(let ((display (imagex-sticky--current-textprop-display)))
(when display
(cl-destructuring-bind (image begin end) display
(let ((new (funcall converter image)))
(plist-put (cdr new) 'imagex-manual-manipulation t)
(imagex--replace-textprop-image begin end new))
(throw 'done t))))
(error
(setq err (append err err2))))
(when err
(imagex--message "%s" err))
(imagex-sticky-fallback this-command))))
I see no possible causes that could suggest why this fails on Linux and works on Windows. Any suggestion?
