Michael R Sweet	cad8f450ab	Multiple fixes to allow PDFio to read more edge-case PDFs. - Update _pdfioFileGets to allow for really long lines where it doesn't matter if we lose the end of the line. - Update "startxref" detection at the end of the file. - Refactor repair logic so that you just get a single WARNING about the repair (debug messages available for testing) - Allow whitespace after the "obj" in the object header. - Make sure to close xref stream on error. - Update predictor code to support Colors <= 32 (some implementations set Colors to the number of bytes per record in the xref stream, which prevents the predictor from doing anything...) - Allow CR CR in xref table. - Clear old trailer/root/pages/etc. objects when repairing, update existing objects that were already found in load_xref. - Don't set current object in pdfioObjectCreate/OpenStream if the stream can't be created/opened.	2025-04-24 11:09:54 -04:00
