How to Merge Multiple PDF Files Into One PDF
Merge 2 pdf files in iOS
any other method to merge pdf file with annotation
Please Help me
For adding annotations to a PDF document I suggest you use this library which provides a sample code of PSPDFKIT. Also please follow this link which has loads of methods and libraries to add annotations to a PDF file. The first one is the PSPDFKIT itself which is free as a demo version but includes namely all kinds of functionalities you would need generally.
Create PDF Annotations in iOS
If you have Adobe Acrobat Pro you can:
open one of the pdf you want to merge
open the menu Comments (top right)
under "Comments List" click on the option icon cf the printscreen
select Import data file and select the second pdf

how about PDFTron package

Answer
can anyone know how to implement annotation in flutter app by using syncfusionpdf package?
We can able to add, remove and modify the annotations from the PDF document using Syncfusion Flutter PDF. Please find the documentation to do the same from https://help.syncfusion.com/flutter/pdf/working-with-annotations. And please find the android studio sample from https://www.syncfusion.com/downloads/support/directtrac/general/ze/AnnotationsSample-535190409. Please find the feature list supported by Syncfusion Flutter PDF from https://help.syncfusion.com/flutter/pdf/overview#key-features-of-syncfusion-flutter-pdf.
I can't edit the existing document page.
We can able to add text, images, headers and footers, lists, tables, bookmarks, document security and annotations in new and existing PDF document. But as of now we do not have support to remove or edit text and images in an existing PDF document.
I implemented but the annotation is not visible in my app.
We cannot able to reproduce this issue in our end. Please provide the below details to validate further in this. 1) Which viewer you are using to view the PDF document. 2) Device or browser details. 3) Sample output PDF document with added annotations
In our application we are using Itext Pdf 5.5.3 library.
We have checked with some of the pdfs in which Checkboxes displayed correctly(check/uncheck) .
However there are some pdf with RadioBoxes and do not display radiobutton(on/off) correctly.
I also use this link to validate pdfs and java code
String[] values = form.getAppearanceStates("Checkbox");
return null values.
Also tried Itext RUPS and found that pdf which are working shows Form Field Names in RUPS Form Tab. And PDfs which are not working do not display form fields.
I tried generating pdf from word document and it doesn't display form fields in RUP , neither I can check/uncheck checkbox in Adobe Acrobat Reader.
What could be the solution to display radiobutton with check on / off ?
Edit -
I had created sample web application to reproduce the issue.
Please setup attached web application and let me know the fix for the issue.
Please download from this link
You have successfully discovered the difference between interactive PDF forms and "flat" PDF documents that look like a form to the human eye, but that aren't interactive forms.
To make the "flat" forms interactive, you need to open those flat documents in PDF editing software (e.g. Adobe Acrobat) and you need to add a form field manually.
You can ask Acrobat to guess where it should add fields, but Acrobat will be wrong in many cases for obvious reasons. You always need a human if you want it to be done correctly.
As for creating an interactive PDF from Word... Forget about it. Use OpenOffice or LibreOffice.
I have a requirement to read a pdf file having tabular format data only like in excel file. I need to extract the cell value of given pdf file.
Is it be anyhow possible using itext API. If you have something to share then please share it or any other solutions?
The PDF format is just a canvas where text and graphics are placed without any structure information. As such there aren't any iText-objects in a PDF file. In each page there will probably be a number of Strings, but you can't reconstruct a phrase or a paragraph using these strings. There are probably a number of lines drawn, but you can't retrieve a Table-object based on these lines.
In short: parsing the content of a PDF-file is NOT POSSIBLE with iText.
You can try this! This lets you read PDF pages.
I recently ran into this problem. I wasn't able to make it work with itext.
An alternate solution I found was to open a PDF document in Adobe and export it to xml. At least with my PDF's it preserved the table information and then I was able to programmatically work with the XML to generate tabular files like excel etc.
The other issue I ran into was that Adobe only lets you export one file at a time and I had lots of files. Luckily Adobe also has a merge function. I ended up merging all the files together and then exporting them as one big XML file and working with that file to generate what I needed.
I am using mupdf to render PDFs in my c++ application but I also need to edit PDFs (inserting a picture for example) but I cannot for the life of my figure out how - it's not documented very well. Ghostscript says that there is an API in mupdf to modify PDFs here http://www.ghostscript.com/MuPDF.html.
Ultimately I am hoping to be able to edit PDFs using MuPDF rather than using another library.
Any help would be appreciated, thanks!
The modification API in MuPDF is for editing the structure of a PDF (such as reordering pages, adding or removing annotations, etc) at a fairly low level. The graphics in PDF are based on a "content stream" object containing the commands for drawing a page using a subset of PostScript. There are no functions for editing these graphics content streams in MuPDF.
However, if all you want to do is add an image on top of the page, you can do so by creating an annotation object for the page. You'll need to create the PDF dictionary objects for the annotation, an image object, an appearance stream to draw the image object, and hook them up to the page. You'll need a good understanding of the PDF format to do this though.
You'll want to use the latest git checkout of MuPDF since we've recently (post 1.0 release) added some convenient functions for editing objects and updating streams with new content.
I know that forms in .pdf made by Adobe Acrobat can act like questionnaire or application blank for filling input fileds and saving results, but is it possible in a way to add more interactiviry to them
- add file upload or attachment to resulting document?
It's kind of possible.
You'll need to add Javascript code to your documents. The code should show Browse For File dialog and import selected file to the document. Please have a look at Import Named File Attachment script (at the bottom of the page). I doubt that this solution will work in Adobe Reader or alternative PDF viewers, but Acrobat Professional should do the trick.
Another solution is given is this thread on Adobe forums:
...I figured out a roundabout way to attach files in adobe reader (not
the full blow adobe acrobat reader). Via Adobe Acrobat 9 Pro I
created a blank form with the "comment/mark up" tools enabled. Then I
merged that file with the other PDF form that was formatted with
fields, radial buttons etc. I had to create the blank form for the
attachments separately because if I tried to enable the "comment/mark
up' tool on the form with fields and radial buttons it disabled the
fields. ... The comment markup tool then allowed me to attach files
via the "attach file as a comment" option.
