Good day to all Using > library(pdftools) Using poppler version 23.04.0
I get a number of warnings such as: > pdf_subset(infile, pages = 156:157, output = outfile) WARNING: /Users/jla/Library/CloudStorage/Dropbox/7cordas/Caio/record/90 NEW RODA SONG BOOK.pdf (object 7 0): object has offset 0 WARNING: /Users/jla/Library/CloudStorage/Dropbox/7cordas/Caio/record/90 NEW RODA SONG BOOK.pdf (object 175 0): object has offset 0 WARNING: /Users/jla/Library/CloudStorage/Dropbox/7cordas/Caio/record/90 NEW RODA SONG BOOK.pdf (object 254 0): object has offset 0 This does not prevent from getting the pages extracted properly and written to a pdf file which is readable. Aging is probably the cause of my irritation with such warnings. I assume there is a problem with the source pdf file which was assembled by music amateurs using various sources. My question maybe out of the scope of this list is: How can I detect and potentially correct using appropriate open source software what is wrong with the pdf file. I am on macos. Thanks for any pointers and best wishes, Jean-Louis ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide https://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
