| COSObjectImporter |
Deep-clones a value (and everything it transitively references) from a
source COSDocument into a target one, allocating fresh indirect
object numbers. |
| NumberTreeUtil |
Looks up a value in a PDF "number tree" (/Nums leaf array of
[key1, value1, key2, value2, ...] pairs, optionally split across
/Kids with /Limits ranges for large trees) -- the
structure used by /StructTreeRoot/ParentTree, /PageLabels
and a handful of other PDF constructs.
|
| OutlineTree |
Reads and prunes a document's outline (bookmark) tree (/Root/Outlines,
ISO 32000-1 12.3.3) via its /First//Next sibling chain (each
node's own children, if any, live under its own /First//Next
chain one level down).
|
| PageAttributes |
Walks a page dictionary's /Parent chain for an "inheritable" page
attribute -- /MediaBox, /CropBox, /Resources (ISO 32000-1
7.7.3.4, Table 30) -- that the page itself doesn't declare.
|
| PageTree |
Walks a parsed document's page tree (/Root/Pages/Kids/...),
resolving indirect references at every step.
|
| PdfDates |
Formats a Calendar as a PDF date string (D:YYYYMMDDHHmmSSOHH'mm',
ISO 32000-1 7.9.4) -- the format used for /Info's CreationDate/
ModDate entries.
