Some PDFs display blank white page about ios-pdf-reader HOT 3 OPEN

This seems to be related with this one.

I've changed changed the rotation code blocks with the following on PDFDocument & TiledView.

 // Flip the context so that the PDF page is rendered right side up.
context.translateBy(x: 0.0, y: scaledPageRect.height)
context.scaleBy(x: 1.0, y: -1.0)
let transform = page.getDrawingTransform(CGPDFBox.mediaBox, rect: scaledPageRect, rotate: 0, preserveAspectRatio: true)
context.concatenate(transform)

These changes seems to fixed the issue in my case.

I had the same problem with a couple of PDFs there were created with an old version of Ghostscript (which had a documented bug).

The only way I found to overcome the problem has been to use a recent version of gs to re-save them, e.g. gs -sDEVICE=pdfwrite -oCorrect_PDF.pdf Problematic_PDF.pdf .

That said, I can't understand why Preview, iBooks and iOS 11 PDFKit (which I'd prefer not to use for my particular app because of the way the thumbnail bar behaves) all can correctly open the original PDFs.
