example usage

1. invoke org-xopp-new-figure and choose a name for the new .xopp file
2. a link will be inserted in org mode, hit save (in org)
3. draw something in the xournalpp window that opens, then hit save in xournalpp
4. reload org file (kill/reopen or using find-file)
5. the figure you drew will be inserted in the org document without the background (transparent and trimmed with background removed).

installation

using elpaca:

(use-package org-xopp
  :after (org)
  :ensure ( :host github :repo "mahmoodsh36/org-xopp" :files (:defaults "*.sh"))
  :config
  (org-xopp-setup))

using straight:

(straight-use-package
 '(org-xopp :type git :host github :repo "mahmoodsh36/org-xopp" :files (:defaults "*.sh")))
(with-eval-after-load 'org
  (require 'org-xopp)
  (org-xopp-setup))

features

• two org links are defined, xopp-figure and xopp-pages, the first is used for figures (single-page drawings) and will be extracted and previewed in org, the latter is embedded in the pdf exports as part of the document (without extracting figures).
• xournalpp pages are embedded into org’s pdf/latex exports
• images are rendered asynchronously so they dont affect org-mode’s startup time

requirements

• imagemagick: convert command should be available.
• xournalpp

todos

• only regenerate pdf/image files if the corresponding .xopp files have changed
• handle edge cases (errors in image generation, etc)
• live sync of figures (automatically display changes in org every time a linked .xopp file is modified)
• more customization options
• implement image centering (the behavior in the picture is from my config and depends on functionality from the dev branch of org-mode)
