PDF to notes

Using the poppler library (https://poppler.freedesktop.org/) the add-on converts a PDF file into notes.

• Question/prompt extracted from each page (the first line of text)
• Convert PDF pages to separate "normal" (front/back) notes or separate clozes in a single cloze type note.
• PDF pages inserted as images or HTML (using poppler pdftoppm and pdftohtml).

• PDF file (can be multiple): select file(s) to convert.
• Deck: Which deck the added note(s) will be inserted into.
• Note type: Which note type to use for insertion, supports "normal" (front/back) note types as well as cloze note types.
• Subdeck: If checked a subdeck (with the PDF file name as title) will be created for each file. Note that if note type is a cloze style note there will be one subdeck for each note.
• Front ("normal" (front/back) note type): Which field to insert the "question" (first line of text in the page) in.
• Back ("normal" (front/back) note type): Which field to insert the "answer" in.
• Title field (cloze note type): Which field to insert PDF file name as title (for note types, such as the built-in cloze, that do not have a suitable field for this, select ).
• Cloze field (cloze note type): Which field to insert clozes into. Clozes are inserted as prompt: {{c1::
  answer}}
  where prompt is the first line of text extracted from the page and answer is either an image of the page or a
  with the page HTML.
• Format: Format to insert the pages in, either as images (will preserve exact layout and work well on all screen sizes but no editable/selectable text) or HTML (does not give perfect results on any screen, especially not small screens but text can be copied/edited).
• Configurable keyboard shortcut (default Ctrl+Alt+P) to open dialog from main window
• Fit width/height: output will be scaled proportionally to fit inside the specified box (0 means not constraint in that direction, i.e. 0 x 0 means no scaling and 600 x 0 means output will be 600 px wide and height scaled proportionally).
• Return will select the current item (same as space) whereas Ctrl+Return will start the import and Escape will cancel the dialog.

Installation

• Windows binaries of poppler are packaged in the addon (https://github.com/oschwartz10612/poppler-windows).
• On many Linux installations it is included in the default install, otherwise install with a package manger, for instance apt: sudo apt install poppler-utils.
• On macOS it can be installed with the homebrew package manager: brew install poppler (untested as I don't have access to a Mac).
