PDF File preview

Hi,
in Salesforce lightning in files or Notes/Attachments of a contact or account you can see a preview of the first page from a stored pdf.
How is that possible?

Here is the code which I extract from the page.

Hello,

Behind the scenes lightning framework does this work while uploading the file, some code creates a thumbnail while uploading the file which can be done using some javascript.

There are multiple javascript & jquery plugin available to perform such operations. I cannot say that which plugin or code is used by lightning behind the scenes but this is possible using scripting.

Here is a jQuery plugin for an example (http://www.phpgang.com/how-to-show-image-thumbnail-before-upload-with-jquery_573.html

Hope you find this helpful.
