Use buttons that have no fill and no stroke and place them over the icon artwork. Should work but and this is a very big but, interactive PDF on mobile devices is still a bit of a crapshoot. The reader app will determine how well they work.
So, the $64,000 question: What app are you using?
Definitely PDF Expert will work on an iPad ($US 9.99 from Readdle). Acrobat DC (formerly Reader) for iPad will NOT work. I haven't done a recent test on other apps.
PDF expert is a no go - as not realistic to ask clients to pay additional and install readers etc.
Bob: I suppose it's down to the mobile device, so it could be any pdf reader that is installed on the users device.
What I did was hyperlink them but set the next page manually and the previous page manually.
Interactive PDFs should be easier than this.
You’re preaching to the choir.
Any reason why the option for Hyperlinks to move to the next page is not there?
You can this functionality in Acrobat, but it's missing from InDesign.
Are you referring to the hyperlinks panel or the buttons and forms panel?
Sorry, but I never use it for the work I do. I always wind up using buttons.
Way more flexibility for me.
Bob, is this what you are suggestion.
Overlay "hotspot" button.
Include interactivity in the hotspot.
Can you confirm this works on the ipad?
It's always app specific. With which app? Many (most?) won't support button interactivity.
It is indeed what I would do, but as Steve points out, you need to test anything for mobile on a device with the intended app.
I wish it were as simple as a yes or no answer but with interactive PDF on mobile devices, it’s still the wild west.
We've agreed for the client to use Acrobat Reader, which works with the tests we did.
Thanks for the advice.
