iPad Mini 4 Fails Extreme PDF Torture Test: Part Two

image

The Processed World PDFs from the Internet Archive are hell on wheels. They use JPEG2000 images which bring just about everything to its knees.

Still, these are things I want to read.

So I’m still hoping there will be a tablet with the strength to do these. Otherwise I’ll just have to convert them into a less strenuous PDF format.

Downloading in Safari:

Waiting for Safari to display:

Finally:

Sent to iBooks:

But look at how slowly the thumbnail pages are rendering:

I’m able to view some pages:

Until:

And iBooks is brought to its knees, with page one — which had previously been rendered — not displaying:

Things don’t improve in Split view (Safari at right):

image

Split view, in fact, fucks it all up. Look at the bottom, at the page thumbnails — now some are missing:

Things aren’t any better when scrolling it in Safari:

Split view in portrait makes things even worse, as even more thumbnail pages disappear:

And no hopping from page to page:

image

Back to landscape Split view:

And the missing thumbnails are different!

What an absolute disaster.

But you know what?

I would have been absolutely shocked if this PDF has worked.

This is why I call this PDF an Extreme Torture Test.

I don’t expect anything to pass this time for some time yet.

And by that time, I will have converted these PDFs and already read them.

This is simply a test. Failing doesn’t matter. It’s expected.

    Those JP2 files are brutal. I don’t really see the value in preserving the format – better to convert it to a more standard straight .jpeg I think. Good luck with these.

    • Yes, at one point earlier, someone from the IA said they’d have to convert those from JPEG2000. They haven’t yet. If I convert them for myself, it’s no big deal, however. The files balloon in size, though.
