Extracting a page
I'm trying to break a PDF down into individual pages. Although it
functionally works, the pdf for each page ends up being almost the size of
the original PDF (250MB). I've seen some references in deleting
annotations which might include links to other pages/resources. I've tried
the below, but no luck. Can someone let me know what I'm doing wrong?
(Below code is in Kotlin). I've also tried using addPage vs. importPage,
since the later creates a deep copy. Same result.
doc.pages.forEachIndexed { idx: Int, p: PDPage ->
val newDoc = PDDocument()
val newPage = newDoc.importPage(p)
newPage.annotations = null
newPage.resources = null
newDoc.save("/tmp/$idx.pdf")
newDoc.close()
}

Threads tie non-contiguous text blocks together in reading order (think
of a magazine with articles continued on later pages)

Tilman, thanks for the reply. I replied to you on stackoverflow, but
thought I'd add here as well, in case someone else has the same problem and
searches the archive.
I figured this out. I had to remove the PDThreadBead (setThreadBeads) on
each page after importPage and before saving it. I went through the process
of elimination here. Page looks great. I'm not sure what a thread bead is
(can't seem to find it anywhere on the web) and class docs don't help.
Thanks!

I could look at it but I'd need the PDF. Please upload to a sharehoster.
