Hello SD team,

My system is iOS 9.1 on Ipad mini 4

Situation
In some documents, a part of the pages has to be seen in portrait layout, and another part has to be seen in landscape layout. Unfortunately, in the second case, the pages are sometimes shown in portrait layout. In that case, we need rotate the device without rotating the screen or rotate the head.
For examples:
Skyguide Swiss VFR Manual, LS MAP 0200, VFR MAP 2 APP 1
Skyguide Swiss VFR Manual, SUP 001/15, VFR RAC 5-1 SUPPLEMENT 2

Suggestion
I know that it is very difficult to handle automatically and could be an Herculean task to manually verify and do it at each update. Consequently, I do not report that as a problem.
For those reason, I propose to add a rotation feature in the document browser to rotate on the left or the right at least one single page. The best would be to choose rotating a single page or a group of pages

Unfortunately there is no API offered by iOS that we can use to do this, as far as I am aware. I am a little surprised that the built-in PDF viewer (which we use) doesn't offer the ability to rotate pages when viewing them, but there you go.

Yes, that would be true if we wrote our own PDF viewer from scratch using PDF rendering APIs. But we do not; the built-in one is fantastic and duplicating all that effort just to enable page rotation is something there is not a good business case for.

I'd love the Document Browser to do a couple more things than it does on User Downloaded Documents:

1) If you have a file with bookmarks / outline loaded in the PDF, the ability to click the link to the correct page and jump there would be in valuable.  Or in lieu of this,the ability to perhaps enter a page number to jump to.   I mention this as I use a large file containing plates I want to use, with about 460 odd plates in it. It has a nice contents page at the beginning, so I can tell which page number I need, but at present it takes a little while to scroll down and I get finger ache !!

2) It would be fantastic, if you have a user loaded PDF open on the document browser, back up to the chart and plog for something, then go back to Plates--> Document Browser, if it would display the last page it currently had open.

I am guessing from your earlier comments that here are significant limitations in the PDF viewer you are using?  Are any of these things possible, or (other than using an external PDF app like GoodReader for instance) are there any clever work-arounds?


Otherwise I really like the plates and document browser feature, especially with AIP and Pooley's plates, and the georeferencing - it is great!

What on earth is a "K-12 straight ahead PDF viewer"?
