I'm using the Overlay creator panel to build a vertical scrolling text panel on a page. As I am saving the folio as a PDF the text within the scrolling (pan) container looks different to the non scrolling text columns. I assume this is because the pan function is converted to PNG or JPG and not built as PDF. Is there a way to build scrolling text panels and retain the sharp scalable PDF text? The only solution I can see is to build the folio as a PNG which withh mean larger file sizes. Help!
You're correct, the text inside the scrolling container is getting rasterized at folio creation time, whereas the rest of the text is getting rendered at display time by the PDF engine on the device. This will result in slight differences in appearance on the device, however if you are creating your folios correctly it shouldn't be a sharpness difference.
Are you trying to create content for the new iPad? If so, make sure you are creating your folio in folio builder at 2048x1536. When you add the InDesign document as a PDF article to a folio that size we will rasterize the scrollable frame content at a resolution high enough to look sharp on the new iPad.
I'm still working at the 1024x768 resolution and viewing on an iPAd 2. The difference on the device screen between the rastered type and the non rastered type is very noticable in standard view as well as zoom.
There will be a difference between the straight PDF and the content inside the scrollable frame. That is, unfortunately, the way it works today. I'm not aware of any workaround if you want to use the zoom capability of PDF articles.
Not so bothered about using the zoom functionality, but the type needs to look the same at standard sized viewing. I will have to save as PNG I guess. It will be interesting to see if this still happens with folios set up for the new iPad. If it does, then designers won't be ale to use scrolling as part of a pdf formatted app, as it looks bad.
I'll add that even if you switch to PNG you will see a slight difference in text weights between text in a scrollable frame and text on the page itself. This is a known difference between how the two are rasterized.
