# Verifying TIFF-F or TIFF-S format: nfxcheck

Determines if the input file is in TIFF-F or TIFF-S format. If the file is in TIFF-F or TIFF-S format, nfxcheck reports its page format attributes, number of lines per page, and bad line indications.

#### Usage

nfxcheck input_file

#### Description

If the input file is not a TIFF-F or TIFF-S file, nfxcheck displays an error message. Refer to the Alphabetical error summary for more information. If the input file is a TIFF-F file, nfxcheck displays the following information:

- Page attributes

- Number of lines per page

- Bad line indication

nfxcheck does not report the TIFF profile used to create the document. The utility cannot differentiate between a TIFF-F file and a TIFF-S file because a TIFF-F file can use the same page attributes for encoding, resolution, and pagewidth as a TIFF-S file.

nfxcheck does not alter or modify the input file.
