How to change the highlight color in pdf using fitz module in python

问题

Hi I am trying to change the highlight color in a pdf but not able to do so. The default highlight color is yellow but i want to change it Following is my code:

    import fitz

    doc = fitz.open(r"path\input.pdf")

    page=doc[0]
    text="some text"
    text_instances = page.searchFor(text)


    for inst in text_instances:
        highlight = page.addHighlightAnnot(inst)
        highlight.setColors(colors='Red')
        highlight.update()


    doc.save(r"path\output.pdf")    

Also how do i search for the entire pdf together and not just one page

and how can i highlight text on an image given in a pdf

回答1:

I think the setColors expects a dictionary, check the documentation here

import fitz

doc = fitz.open("test.pdf")


page = doc[0]

text = "result"

text_instances = page.searchFor(text)

for inst in text_instances:
    highlight = page.addHighlightAnnot(inst)
    highlight.setColors({"stroke":(0, 0, 1), "fill":(0.75, 0.8, 0.95)})
    highlight.update()


doc.save("output.pdf")
