i've written that it's only theoretically ;-)

Robert,

what you want to do is not possible with QuickPDF (at least I cannot imagine any way). Deleting one portion of text from a pdf would require the adjustment of each following text (in short, text in PDF is mostly a collection of letters with position for each letter). So you would have to implement your own algorithms for line breaking, page breaking, ...

The way to hide the text by a form field would still make text extractable as it is not deleted from pdf.
So if you want to do some real editing on a pdf use Adobe Acrobat.


best regards,

Hi!
You can test it yourself.
Do it and then make textextraction... Is it still there?
I can't add anything to the library and i can't say if "yes" or if "not" ...
I'm a user - not the producer.
Cheers, Ingo

If I do this is, does the old text along with the white drawbox objects still exist in that location or does your pdf save functions clean up the overlapping objects? If it doesn't clean up, won't your extract text functions then list the old text as well? If this is the case, then couldn't you just add an objectid to each object you read when converting the pdf to your internal objects and just expose this objectid to all your routines. Then you could simply add a DeleteObject(objectid). This would also allow for a GetObject(objectid), and allow for direct editing of objects. This would open up your PDF library to all kinds of interesting routines.

Thank you,
Robert

Hi Robert!

With the textextractfunctions you can get the rectangle points of the strings (x1, y1, x2, y2, ...). With drawbox-functions you can overwrite the string-locations with color white (for example)... That's your deletion. Now you have these position-points the old textstring and you can use the draw-functions to insert your new textstring ... so you see it's possible to create a pdf-editor but it's only theoretically ;-)

Cheers, Ingo

If I want to change a piece of text or delete it or replace it with a formfield,
how is it done or is it possible. Is it possible to create a pdf editor with your library?
 
Thank you,
Robert
