I am trying to display PDF file on the web without download option and copy option.
Then I found this https://books.google.co.in/books?id=kwBvDwAAQBAJ&printsec=frontcover&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false
Can you tell me how can I achieve this on my website?
What mplungjan said in his comment is correct. Anything that is put on the web can be copied one way or another. It appears that the google site you linked to is just showing an image of each page (see https://books.google.co.in/books/content?id=kwBvDwAAQBAJ&pg=PP1&img=1&zoom=3&hl=en&sig=ACfU3U0s8V3HjcApLeNwIGStMQlzZFaotA) with transparent pixels over each image to make it so you can't right-click to save the image. But it's easy to see what they're doing by viewing the source in the inspector.
If you don't want your users to be able to download the entire file, you could break it up into multiple small files (or images, like google is doing in your link) that would make it a little harder for them to get the files. But you can't really stop them from downloading anything.

My issue is that I have to deploy a local server (without internet), so I cannot use Google Doc Viewer in this case. All I want is to restrict the user from download or printing the document. I have tried hiding or removing the toolbar in JS but it is not working out.
You may be able to disable the toolbar somehow, but that isn't good enough to keep users from downloading or printing it anyway, and nothing you can do will be. If a person can see something, they can copy it, no matter what you try to do to stop them (and all trying will do is inconvenience legitimate users). Previous similar questions:

disable downloading of image from a html page

Although those talk about images, the exact same reasoning applies to PDFs.
I do have a pdf embeded in to the page. It does work and it has it's own buttons, like print, download, rotate, zoom-in, zoom-out.
Is it possible to control these buttons from javascript? I want to show the pdf, but the buttons for download and print I want to control by myslef, with different design and placements outside of the embeded element.
TO sum up, I want to hide all buttons which is shown to the user from the default pdf viewer, except the page number, and I want to separately create donwload and print button with my own design but with the same functionality.
I've done a little bit of research and I found this: https://bugs.chromium.org/p/chromium/issues/detail?id=135146
which is yet has unknown status. Does it mean the API for Chrome pdf viewer doesnt exist? I couldnt fine any.
Another solution is to integrate PDF.js in my own web app, which is heavy (almost 2.6mb zipped) and time consuming.
Any idea is welcome.
At work they want to do this to prevent people from downloading images easily from our site. They won't go the disable right click option, so they want to do what Flickr is doing:
http://www.flickr.com/photos/scg/12332332454/sizes/l/
If you right click and try to download that image it downloads the entire html page instead. Can this be done via JS or is it something handled by the server?
I know all this goes against usability and doesn't actually prevent people from ripping off images but it's what the ticket I'm assigned asks for.
I have a link as:
PDF
I want to set a tooltip for this link and in tooltip display the same pdf file.
That means i want to display the contents of testpdf.pdf file in tooltip when mouse over the link.
I searched that for in google, but there have no link siutable for me.
There have a lot of model for image ,text in tooltip.
How can I do this?
Anyboady have any solution?
Displaying a PDF generally involves launching a browser plugin, such as Adobe Reader, which has its own menu bar, toolbar, and so on. Cramming that into a small space like a tooltip probably isn't very practical.
You'd be better off rendering a thumbnail image — maybe use a PDF library on the server for this — and showing that in the tooltip.
You can try pdf.js
It renders PDF files onto canvas..
But in my opinion it is not a good solution at all, when the PDF is big, it will take some time to load it into the tooltip..Better is to create a thumbnail on the server and display it as a standard image..
Here is how to do that with PHP
I think that requires the browser to have a plugin to display PDF inline instead of downloading it. Once this is ensured, you can set the target of your tooltip to the URL pointing to PDF. What tooltip library are you using, btw?
I want to give the user possibility to paste an image into a webform. I don't need to display the image, all I need is the image's location.
I know it's possible because the guys at CKEditor(and other editors) are doing it.
If you go here, http://ckeditor.com/demo and paste an image you copied and then right click on it and go to image properties you'll see they have the image's address.
How can this be done?
Thanks
It is not possible because giving a browser the possibility to access local files, which have not been added to be uploaded explicitly by the user, opens a variety of very dangerous security holes that would certainly be super-exploited by hackers.
A good solution would be to give the posibility to upload using Ajax and link the images in the document once they are available in the server.
Take a look at “Sending files using a FormData object” part of the Using XMLHttpRequest document at Mozilla Developer Network.
