TOPIC: Hide a part of the pdf in pdf preview?

Watching your demo, I noticed that the pdf preview means getting the complete pdf on your screen. This is very easy to copy with a screenshot.

When I offer a pdf preview, I would like this to be just half a page of the complete pdf. The rest of the pdf should be invisible.
Is is possible to show only half a page of the complete pdf?

PDF preview and PDF for sale are DIFFERENT documents

In our case it's just to show the functionality, in your case you will preview only first page or two of your documents, so don't worry documents can not be stolen via preview!

Cheers!

Thankyou for your reply. Just one moer question:

Is half a page also possible?

It works like this:

You select a PDF for sale and upload it
Then click on the "Click here to add preview" link and you add a PDF file for preview.

Basically you upload both the preview and the pdf for sale, this way you can put anything you want as preview.

Sounds great. I'll check it with my webmaster. Thankyou for your reply.

Is it possible to give your customer a code which allows him to download all the pdf-files during a certain period?

For instance, customer pays a fee for a year and during this year he can download all the pdf's as much and as often as he wants to?
