How do I add a clickable area with an external link?

[steinerlein]

Hi, I'm looking to add clickable links to existing PDFs.
I can already retrieve the location of corresponding Text and I can also construct the file destination.
However, it is unclear to me how to actually insert a clickable area.

Here's what I have so far:

import re

doc = fitz.open("RST-004285_00.pdf")

page = doc[0]
blocks = page.get_text("blocks")
blockRects = []
for block in blocks:
    stringPart = block[4]
    parts = stringPart.split("\n")
    try:
        if re.search("rst", parts[2].lower()):
            print(parts[2]+"-"+parts[3])
            blockRects.append(fitz.Rect(block[0], block[1], block[2], block[3]))
    except IndexError as e:
        pass

for block in blockRects:
    page.add_squiggly_annot(block)
    blockLink = fitz.Link
    blockLink.rect = block
    blockLink.uri = "C:/Users/Farid/Desktop/test.pdf"
    blockLink.is_external = True
    page.insert_link(blockLink)
    
doc.save("a-squiggly.pdf")

I understand handling links is a new feature and if it's not possible to do what I want, please let me know :)

Thanks!

On the contrary: it is quite an old feature 😉and you sure can do it.

Some background:
Links and annotations used to be supported for all document types in MuPDF. Annotation support has then been restricted to PDFs at some point.
In PyMuPDF, annotations have been added much later than links. This is why they are handled via a differently looking API.

There is page.insert_link(link) to insert a new link on a page. The argument must a dictionary as described here, look at section heading "Description of get_links() Entries".
