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.

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.

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
I would like to edit an existing pdf document,most probably comes from the server. My requirement is to edit the pdf document. Here editing means i want to add some text at some particular place. Whenever user clicks on a document at some place where he wishes to enter the text, keyboard should appear and can able to write some text. In the same way, he should be able to delete some of the text which he doesn't want to use in the existing document. After all these manipulations he should be able to save the document. I have been trying with fastpdfkit framework, everything is possible but entering text and deleting is not working which is the main requirement for me. Anybody who had worked with this kind of requirement could probably help me.
you can try with fastpdfkit.
Download the sample code form github and make use of it.
Try following demo of Leaves framework
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 wanted to create a PDF with a Text Annotate. I came across the 3rd Party library called libharu. Can anybody tell me how to create a PDF with a text annotate using this library or any documentation related to it.
The libharu site has an example of annotation in C.
