How do I add annotation to existing PDF

I own date for add annotation that title & contents & pageNo & coordinate value.I want include annotation to existing PDF utilizing these information. I tryed to add annotation to existing PDF using pdfbox( Java). I might add annotation new page that was placed into the tail end of an existing page, However I can not include annotation to existing pages due to the fact that of can not understand how to access existing pages and ways to add annotation to page.

To include annotation to existing an page, do this:

PDPage page = (PDPage) doc.getDocumentCatalog().getAllPages().get(0);
List annotations = page.getAnnotations();

To see where your annotation is, either click in Adobe Reader on the last page on “Comments”, “Remarks list”. To make the annotation more noticeable, include this:

PDGamma colourBlue = new PDGamma();
colourBlue.setB(1);
txtMark.setColour(colourBlue);

Is there any good tool readily available for PDF annotations in the browser? Situation – User sees the PDF in browser, marks annotations, annotations then save in database. When user opens the PDF once again, the annotations are applied to PDF after rendering.

Annotations connected in some way to the content underlying it or simply sticky notes at X, Y area at page Z? Then your question needs connecting the browser display screen and zoom level to page coordinates, if its only annotation at X.Y on page Z.

I wish to include text or annotation in the exsting pdf file to interpret some crucial words.

In the beginning I tried the pyPdf & reportlib to combine t he initial pdf file & new produced interpretion pdf file, but it does not work. Since the initial file keep out all the words of interpretation pdf and make brand-new pdf file unnoticeable. If I check to combine 2 new created interpretion pdf file into one, it works well.

I am trying to create a pdf annotator utilizing PDF.js and a HTML5 drawing app to produce a JSON file.

Hypothes.js supports text annotation of PDFs (by means of PDF.js and Annotator). The plan at The Hypothesis Job (a non-profit … likewise where I work, fwiw) is to upstream the PDF related functions that have been made to its personalized Annotator, so they’ll be available to more designers.

Here’s an example of Hypothes.is filled on a PDF via a proxy. The very same functionality is offered without the proxy using a bookmarklet in Firefox or the Hypothes.is Chrome extension.

Furthermore (if you’re wanting shape drawing on top of PDF.js rendered PDFs), you might have a look at the Annotorious polygon preview. Much like what you’ve described, plus annotation, plus storage … though I do not think it deals with PDFs … simply images.

There is also continuous work being done at the W3C to construct an interoperable annotation data design. Checkout the Annotation Working Group to learn more.

Finally, PDF.js is also getting work done to it now to support PDF-level annotations. Eventually, it needs to provide PDF.js a strong foundation for exposing annotations packed from other sources.

This might be an old thread but simply in case somebody else stumbles upon this post, there is a layer called Annotationeer that allows you to create annotations. This can be modified to likewise to deal with images rather of its default combination to pdf.js.
