隐藏/禁用Chrome PDF Viewer上的下载按钮

Question

I'm looking for a way to hide or disable the download button that appears in the Chrome PDF viewer. I have disabled the print button using the protection script of fpdf(http://www.fpdf.org/en/script/script37.php), but it doesn't help with the download button. The PDF is currently being opened in a new window via :

window.open(URL, "", "resizable=yes, scrollbars=yes, titlebar=yes, width=1024, height=900, top=10, left=10");

I realize this won't stop any somewhat informed user from saving/printing the PDF, but the client is insisting on this "security measure".

If I inspect the element using Dev Tools and add display: none it does what I want, but I'm not sure how to add that by default in the new window that opens.

Since you are delivering pdf file directly into the browser, displayed using Adobe Reader ActiveX, how can it be possible to prevent file download, since the files are displayed after downloaded into your temp directory?

So it is not possible using ANY JavaScript library.

The only way to secure your master PDF files is by creating Images for each page and present those to the user on the web via your own interface (html, flash etc).

You may use ImageMagick along with GhostScript for this.

You may go through veryinteractivepeople

Hope this helps. (:
