Purpose. Query properties of the currently open import file — a cluster of pdfGetIn* getters supplementing the /Info-focused set already covered in Document Info & Structure Tree.

Description. pdfGetInIsCollection/pdfGetInIsTaggedPDF/ pdfGetInPageCount all fail with the distinct NO_IMPORT_ERR sentinel when no import file is open (the same documented DIFF pattern as pdfGetInPDFVersion above); pdfGetInRepairMode/pdfGetInOrientation do not follow this convention — they simply return a default/0 value without the distinct sentinel if no import file is open, an inconsistency across this otherwise-uniform pdfGetIn* family worth being aware of when distinguishing "no import file" from "import file open but property is false/zero."

Parameters.

Return value. pdfGetInIsCollection/pdfGetInIsTaggedPDF/ pdfGetInPageCount: the value, or NO_IMPORT_ERR if no import file is open. pdfGetInRepairMode: True if the import parser had to repair-mode-load the source file (a real signal of a malformed input PDF). pdfGetInOrientation: the page's rotation in degrees; 0 if IPDF invalid or PageNum out of range.
