You may want to add org in Package-Requires list.
Note that org-add-link-type is deprecated for org-mode 9.0.

This function is obsolete since Org 9.0;
use `org-link-set-parameters' instead.

Until this package goes to Melpa, it would be nice to have a configuration snippet in the README to install automatically org-krita. quelpa-use-package can do it as follows:

  (use-package org-krita
    :ensure t
    :quelpa (org-krita :fetcher github :repo "lepisma/org-krita" :files ("*.el" "resources"))
    :config
    (add-hook 'org-mode-hook 'org-krita-mode))  

The line above is doubtful. This is why:

1. org-krita-insert-new-image ask for a filepath (without specifying any constraints). Suppose the user fed it /path/to/myimage, then resources/template.kra is copied to /path/to/myimage.
2. The line 100 try to compute the .kra path by substituting the extension to .kra (or appending .kra if there is no extension). Consequently, (expand-file-name (f-swap-ext "/path/to/myimage.kra" "kra")) evals to "/path/to/myimage.kra". Then, krita try to open "/path/to/myimage.kra" which doesn't exist.

Conclusion:

• If the filepath fed doesn't have an extension or have another than .kra, then it's not possible to edit the canvas.

I'm not sure why the extension should be added/substituted (maybe for windows ?), but at least the file should be renamed accordingly & this behaviour should be documented somewhere (e.g. prompted).

Hi @lepisma ,

Nice macro. Yet could not figure out configuration info. Appreciate if you post.

Cheers, and stay safe,

Hey, thanks for the neat tool! I couldn't get the 'org-krita-insert-new-image' to work interactively. I have reworked the function to remove the arguments, which fixes the issue.

From this answer of emacs.SE, we can display online image in an Org buffer (actually only .png, still requires some investigation for others). It would be interesting to integrate the feature of org-yt (which is not a complete package as its purpose was answering an emacs.SE question). Some features I can imagine are the following:

• Consider the link [[krita:<https-link>]]
  • Display the online image whose the url is <https-link>.
  • Edit it with C-c C-o (as it was an offline .kra), save the edited image to a .kra and overwrite the old link (prompt if necessary).
  • Export to pdf & html with possibly mixed online and edited images.

An interesting workflow would be, for instance, using org-protocol-capture-html to capture a web page as an Org buffer, then be able to edit the online images captured.

Hi, I just wanted to let you know, that i ported org-krita for xournalpp.

I'm sure I'm doing something wrong, but I don't seem to be able to get actual previews. When I toggle the mode on (org-krita-mode) the links just turn into boxes with horizontal lines through the middle no matter what the actual krita .kra contains.
