Creating a 'scratch off panel' within a PDF document

[tony8028]

Hi everyone

My client wants to create a PDF doc that has a game ticket style function, ie a little panel that a user will 'scratch off' to see what they have won.

Is there such a technology within PDFs that I could use to replicate this?

thanks!

You can make a thing visible when someone clicks somewhere. That could be a bit like the mechanical aspect.

If you are thinking of making this have real prizes according to what people scratch, forget that -- a motivated person could easily find out what is hidden and make the right scratches.

Thanks for the response.

How do you make things visible based on a click?

The way the tickets work is that the customer scratches off all of the panels so they cant really cheat as such as they are only dealing with the cards they are dealt.

You can use a field button which changes the displayed icon when the mouse moves over it.

No.

There is something similar, actually. You can draw the "cover" using the Pencil commenting tool and then the users can "scratch it off" using the Eraser commenting tool. However, they can also just click the Pencil comment and press Delete to remove it all at once...

Thanks for this info.

Would these solutions all the require the user to own the full version of acrobat or will this also work on the free vanilla version?

It will work with the free Reader.
