how to find de text's xref？

Text does not have that!
Use redaction annotations.

[JorjMcKie]

There is a detailed example in the utilities repo for removing an image.

[better319]

ok,i got it ,but i haven't found the example for del text.
would you like to help me find the url?
THK!

[JorjMcKie]

Look up Page.add_redact_annot() in the documentation.

[better319]

yes, it's a magic work,

`
r = fitz.Rect(1, 1, 700, 20)

page.add_redact_annot(r, text="", fontname=None, fontsize=11, align=0, fill=(1, 1, 1), text_color=(0, 0, 0), cross_out=True)

page.apply_redactions(1)

`
page.apply_redactions(1) #1or 0 all the same?

and the rect was created by myself,

how to get the word's Rect(like:"name:xxxxx")

page.??? which one return rect?

THK!

[JorjMcKie]

You hate reading documentation, don't you 😂?
At least read the tutorial and the recipes please!

Here are some candidates:

• page.search_for("needle")
• page.get_text("words") then search for the word you like

Other text extraction variants also give you the font name and size and color or properties like bold, italic, ...

... and of course all that is no bug ... not even an issue, therefore I moved this to Discussions.
