I am creating a web page which has Video, Study Material in PDF or PPT format.
I want to secure all the Videos, PDF & PPT's, the user cannot download or save it.
And also all the file are stored on my server not on another.
i know Slideshare.net or youtube video embed etc... i guess all this are not secure.
Is there any plugin or any mechanism where my feature are fulfilled??

I have a webform with and want to open it on smartphone - than take pictures of some documents which need to be merged in one PDF, and on the end this file need to be uploaded to server.
My solution is to use Google Drive to upload PDF (scan) to GDrive and then somehow download this file from gdrive to server via some sort of widget (any links appreciate) installed on website.
Maybe someone have a better idea?
I know its late but my answer might help others. I also face the same challenge and implemented a custom solution based on Javascript and Since you are using web form so this solution will perfectly fits on your need.
You have to use JSPdf javascript library, JSPdf provide you pdf object in your browser and you can upload it download it and there are many other thing to play with.
First you have to initialize JSPdf object as per your requirement. I am creating PDF with page size width:500px and height 500px.
pdf = new jsPDF("l", "pt", [500,500]);
Simply when you will take picture from camera you will have each picture in form of base64, that base64 format you have to insert in JSPdf object
pdf.addImage(imgData, 'JPEG', 0, 0);
you can repeat the above code to add pictures from camera as much as you want, at the back-end these images are compiling and creating pdf document where each page have each images in sequence.
Once you are done, you can get PDF object in form of base64 object using below code that you can upload to any server.
pdf.output('datauristring')
above is only pdf part, you can find complete working example including camera part here Javascript Component to Scan Document
as I state on the title, I want to develop a project that having ability to open PDF file within the App (React Native), then later we can add annotation, notes, and sign on the PDF (put writing).
The pdf is from the server, so I assume we can call some kind of library that can open pdf and edit and have those features.
I tried browsing about it and found that PSPDFKit can be a solution, but the pricing is pretty much expensive. Is there any other library that can be use for this purpose?
We are working on creating mobile app using sencha touch frame work. one of our requirements is when user hits view pdf, the user entered form details which stored locally has json format should be rendered and view as pdf and also it can be saved as a pdf locally.
i found that itext is one of the java library which is widely used for pdf generation. but i couldn't find any article inter relating both sencha touch and itext. let me know is that a possible way or any other method available for json to pdf generation in sencha touch.

java has nothing to do with javascript.
A quick Google search of "javascript pdf generation" lists some libraries that may work but getting them to run on a device might be more trouble than its worth id look at submitting the form results to a server and downloading the resultant PDF.
this might point you in the right direction:

Is there any alternative way to view PDF files on the web instead of using Acrobat Reader? I need to control the viewer to programmatically trigger the printing of the document.
The source of the PDF should come from a webservice URL / AspX
The easiest I would think is to use the Google Doc Viewer:
<iframe src="http://docs.google.com/viewer?url=**PathToMyPdfFile.pdf**&embedded=true" width="600" height="780" style="border: none;"></iframe>
You need to host your PDF files somewhere online, may be in a file in your public website ( it needs to be a public site) and put the link to the PDF file in "PathToMyPdfFile.pdf" in the iFrame above. Then set the width and height you need.
Google even generates this code for you here:
https://docs.google.com/viewer
Then simply put this iframe anywhere in the body of your page where you want to display your PDF. This also supports many other file formats too.
There are quite a few options for document views online, some open source others proprietary. Personally, I've had good experiences with Flex Paper. This will allow you to include the document view on your website, and there are some developer resources which will allow you to integrate it with the functionality you're looking for.
For demos, see here: http://flexpaper.devaldi.com/demo/
You can use FoxIT PDF viewer. It's free and programmable.
I am trying to build a mail client app. for ipad that allows you to attach files.
Currently this feature is not supported by native mail.app
I checked some app like good reader and pdf reader lite that allows you to send one file in your email.
They embed the pdf file in the body of email.
So my question is, how are they doing it.
Are they using any kind of APIs(which one) or are are they embeding the pdf in HTML?
Thanx.
