Question: How can I remove annotation border?

[chanhlt12]

I am trying to add a rect annot to PDF file.
And I don't want to see its border.
I tried to set border to None, but it does not work.
Here is my code:

import fitz

doc = fitz.open()
page = doc.newPage()
rect = fitz.Rect(0,0, 100, 100)
annot = page.addRectAnnot(rect)
fill = (0.3, 0.6, 1.0)
annot.setColors(fill=fill)
annot.setBorder(border=None)
annot.update()
doc.save("out.pdf")

There is always a red border around the rect annot as below.

Please teach me how to make it disappear.

This is a bug - fixed in coming version 1.18.5. At the moment, you can only setBorder(width=small) with a small value, or fill color equal to stroke color, such that the border goes unnoticed.
OR
Download a pre-release from here if you are Linux or OSX. If Windows, drop me a note and I'll upload the version fitting your fitz.__doc__ profile.

In this version, you can do this:

import fitz

blue = (0, 0, 1)
doc = fitz.open()
page = doc.newPage()
r = fitz.Rect(10, 10, 100, 100)
annot = page.addRectAnnot(r)
annot.setColors(fill=blue, stroke=[])  # [] ensures omitting the color value
annot.update()
doc.save("x.pdf")

Solved by v1.18.5 being uploaded now.
