We had someone test this internally using CS5.5 and CS6, and v20 of our tools. When the folio was created as PDF, and then multiple articles were imported, the resulting articles are indeed PDF as expected. While you may see a progress window flash past and reference creating a PNG, that is likely for the thumbnail icons used for TOC navigation, etc., and not the actual article.
How are you testing the pinch and zoom functionality? By deploying the folio to an iPad device? Are you creating v19 or v20 folios? (I.e. have you just updated your panel or the tools as well?)
Ok. Good to know.
I was still creating v19 folios, deploying the folio to an iPad device in Adobe Viewer for v19. Only updated the panel.
I'll try later today with v20 of the folio producer tools.
OK - or rather not ok
Installed latest 5.5 and folio producer tools. When importing with sidecar, one mess. Some files are zoomable others not. Without sidecar: vertical (2pages) zooms. Horizontal (1 page) not.
Please test as well with sidecar and horizontal swipe activated. I really like to know what the outcome is.
Authoring of PDF content scales down to the "Auto" setting if the import is done with smooth scrolling articles. This is a decision made to protect the performance in the viewer (smooth scrollingn PDFs crash on occasion).
The alteration of the PDF/Auto setting is done via an algorithm that's complicated, and is dependent on a number of factors related to article length and content. If you'd like to ensure PDF output, do not select the smooth scrolling option.
I hope this helps, thanks.
I know. But it is not smooth scolling that is turned on. Only horizontal swipe. That means if your article has more than 1 page you don't have to swipe vertical but only horizontal. The problem is if you have only one page in an article (horizontal swipe on or off) it doesn't import as a pdf and/or doesn't zoom.
At this moment I'm sure it is a bug.
I am having similar issues with zooming not being functional while previewing on iPad.
I've imported multiple articles with PDF format selected (smooth scrolling set to "never") using Folio Builder 12.2.2 and previewing on iPad in Content Viewer.
Prior to updating Folio Builder to 12.2.2, the PDF zooming was working as expected.
