We are trying to support comments within PDF's. Basically we would like to display the note icon on the PDF and when the user taps on the icon, the details of the note are displayed. Is this currently supported within FPK without custom programming? If not, can you provide some direction on how we would build this? Thanks!

    Hello John,
    currently FastPdfKit doesn't support standard pdf notes on the pdf itself.

    However we are working on that.

    Do you need to display preexisting pdf notes or use custom ones?

    Best regards,

    We need to be able to display notes are were created in preview or acrobat and already exist in the doc.

    Can you give us a timeline of when this might be supported. We have purchased FPK for multiple clients and this is a huge request.

    Hello Matteo,

    Any updates on this? Also, I am wondering if this may be something we could develop ourselves given some direction from you?

    Thank you,

    Would be fine for you to get a dictionary with all the info required to display the annotation (for example as an overlay view)? Basically, this will expand on the -annotationsForPage: method by returning more information in the case the annotation is of type Text.

    Yes, that would work. Is this dictionary available today or would you push an update soon to support this?

    The latter, on the devel branch of the repo. It will likely be an FPKTextAnnotation object rather than a dictionary.

    That's great! When can we expect this to be part of a stable build?

    So do you have an ETA (Date) on when this would be in a stable build?

    We have purchased this toolkit for a client project and they want to push a build live next week. This feature is a deal breaker for the client. Is there a way you can give us an estimate on when this might be supported? If not we may be forced to use another toolkit for this project.

    Thanks for your help!

    Hello John

    We are prepping the above mentioned solution. Due to the structure of the pdf document, it require a bit of work to be done. I'm confident I should be able to provide to you a testable solution within 24-48 hours. I'll keep you up to date.

    That's great news. We really have a big push on this with our client on a very high profile project. Please let me know if this timeline changes. Also let me know when this is ready in GitHub. Thanks again!

    We have added a function to get the entire annotation structure as a Cocoa-friendly object, -cocoaAnnotationsForPage:. The details are in the MFDOcumentManager's header.
    We are also writing an implementation as Widget (FPKExtension) if you are interested in playing with them, that will give some sort of text annotation support out of the box.
    I tried to make public the stream renderer for the annotation appearance stream(s), but it has too many private dependencies still. It's likely you have write your own if you are willing to use the embedded appearance in the pdf annotation rather than 'force' the look of the annotation at application level.

    Just one more note regarding the appearance: most pdf readers just does not consider the appearance stream and override with their own graphic: that is the way Apple's preview works.

    If you accept a suggestion: just use your own picture.

    I just found this thread and anted to ask whether there is a possibility to store the annotations yet. Reading them is nice, but I would require writing the, also.
