我在 Apple Books 中有一本来自 iPad 上本地文件的书 (PDF)。我在 PDF 上做了两个月的笔记。
今天我无法打开它并收到错误:
“无法打开文档。无法打开 ''”
所以我将文件空投到 Mac 上,尝试在 Preview、Adobe 和 Acrobat 中打开它。我在任何地方尝试过该文件,但都无法打开该文件。它可能已损坏或损坏。
我尝试使用Ghostscript( gs
)修复它,但没有成功:
gs \
-o repaired.pdf \
-sDEVICE=pdfwrite \
-dPDFSETTINGS=/prepress \
corrupted.pdf
我收到一个错误:
Catalog dictionary not located in file, unable to proceed
**** Error: Couldn't initialise file.
Output may be incorrect.
No pages will be processed (FirstPage > LastPage).
The following errors were encountered at least once while processing this file:
startxref offset invalid
xref table was repaired
**** This file had errors that were repaired or ignored.
**** Please notify the author of the software that produced this
**** file that it does not conform to Adobe's published PDF
**** specification.
我尝试更新 iPad 并重新启动,似乎没有解决问题。
该文件约为 150mb。我可以做什么来恢复它?
