What you're missing is that for the most part these flipbooks are flash based and will not play mobile devices. I'm not sure what you mean by resizing back to neutral.
FWIW, which may well be nothing, I hate these things and will close any website that presents me with one.
I do know what you mean, that flipbooks are flash based.
We used to upload our PDF of our magazine to a website called PageGangster. They would convert it and I could customise the flipbook before 'activating it'. Pagegangster would host the magazine and we would link to in on our website.
It was a fully functioning flipbook with all the bells and whistles AND it was compatible with all devices and operating systems.
The resizing issue is that the flipbook appears on screen and when you try to zoom in on it. everything around the book will zoom in, but the book itself will not zoom. it resizes back to the original it loaded as. It will not let me zoom in and out on a page.
Basically we are looking for a way to use InDesign to create the same experience PageGangster was providing us with. Pagegangster has since gone under/will not respond to emails so we are unable to ask them for more information.
Does anyone know how they were able to create a flipbook that was compatible with all devices and operating systems?
