Highlight URI

trungng2006 · 11-09-2020, 10:11 AM

I would like to ask how to extract highlights URI.
I want to organize the highlights in another apps and have a small link to remember the position of the highlight, so each time i click the link, it will open up the book in calibre at that highlight position.

For example:
If i extract the highlight and use it in another app, then zotero would give me this URI. Everytime i click it, the PDF file would open up to the highlight position.
(<a href="zotero://open-pdf/library/items/XFXYVKUP?page=24">

Use the browser viewer in the content server and simply copy paste the URL whenever you need a reference. Or if you want to use the standalone viewer, in the viewer controls click Go to and then choose location and there you can copy paste that location and if you need to open the viewer at that location, use

ebook-viewer --open-at "copied_location" file.epub

Oh and in the next calibre release you can get the URL to use with the standalone viewer directly from the Go to->Location page in the viewer controls.

=> i just test this, it is very nice! thank you!

I would also like to ask 1 more question:
I can open book at the location by using this URL:
calibre://view-book/_hex_-43616c69627265/6435/EPUB?open_at=epubcfi(/12/2/4[x9780593083536_EPUB^-4]/2/64/1:69)

I can locate this in the highlight export:
(/12/2/4[x9780593083536_EPUB^-4]/2/64/1:69)

However, i cannot find this "_hex_-43616c69627265" number. May I ask how do I obtain this Hex number?

trungng2006 · 11-13-2020, 02:46 AM

i just found out the hex is "calibre" (applied to all book location URL)

but now i realized i still missing the /12/ in the epubcfi url

epubcfi(/12/2/4[x9780593083536_EPUB^-4]/2/64/1:69)

start_cfi: 2/4[x9780593083536_EPUB^-4]/2/64/1:69

https://manual.calibre-ebook.com/url...ecific-library and the initil number is 2 * the spine index of the file containing the position.

trungng2006 · 11-13-2020, 09:20 AM

Thank you for your prompt reply!

About the initil number, if this is calculated from the spine index, then i think it should be 2*spine index +2?
Could you please help reconfirm?

yes, see the http://idpf.org/epub/linking/cfi/epub-cfi-20111011.html for details.
