Does QuickPDF Library supports Search & Replace Text function?

For example, I want to search for [This information is For:] and replace it with person's name.

Thanks,

Pranav...

Hi Pranav!

You can try the embedded text extract funcionalities.
There are options to get informations like used font,
fontheight, fontcolour and the whole text coordinates
while extraction, too.
So you can extract the text page by page,
search for your text and with the draw functionalities
you can fill the background on the same coordinates with
white colour and on the same position you can write your
new text.

This you can do with QuickPDF. This is not a real search
and replace but it looks like ;-)

Cheers and welcome here,
Ingo

PDF files are not designed for Search and Replace which is why most libraries only allow you to add / append commands to an existing PDF file.

There are some options.

1. DrawText(x,y, text) - but you would need to know where the text is.

2. Use form fields and then you can flatten their contents.

If you are loading existing PDF files that you have no control of then you may be out of luck.
