My project has started in December and thus everything has been designed for 1024x768.
In the meantime the iPad 3 has arrived.
My folio is fully in PDF format. Only the images have a slight raster effect.
I have fully tested the folio on iPad 3 and they are no differences compared to iPad2.
My app has been submitted to iTunes Connect.
What are Apple's app reviewers doing if the app contains a folio only designed for 1024x768 but in PDF format ?
Bob B recomends two renditions.
You create a single 1024 ID file with the high res images scaled down in ID to fit 1024 format.
Export one rendition using 1024 in Folio Builder, then create another using 2048 in Folio Builder. The current set of tools resamples most content including slideshows to the resolution of the rendition defined in Folio Builder.
I have done this and it works in testing although the latest issue of our mag has not yet been submitted to Apple. Maybe someone who has completed the process can continue this thread?
Yes, Graham, I'm doing this now. Everything works brilliantly in testing. Then, once you Publish the folios to the Distribution Service, both renditions become invisible on an iPad 3 - in Content Viewer and in the development app. I still haven't found a solution.
I am not duplicating the InDesign files but exporting two renditions from the same set. All my images are hi-res so they will export appropriately to 1024 and 2048 renditions automatically. However, my magazine contains hundreds of additional images in web view galleries. I didn't have time to prepare two sets of HTMLResources (one for each rendition), so I just prepared a 2048 set in the knowledge that iPad 1 and 2 owners can still get the benefit by pinching and zooming in these web galleries.
All sorted now, I think. It was a case of telling everyone to get out of the car, slamming the doors, and telling everyone to get back in again. Then doing this again, and again, and again, for 12 hours.
