# Converting TIFF-F or TIFF-S files: nfxcnvrt

Converts image format characteristics of an input TIFF-F or TIFF-S file, either according to default values or as specified in the command line, and saves the modified file under a designated new name.

#### Usage

nfxcnvrt input_file output_file [convert_encoding [convert_resolution [convert_page_width [convert_bad_line]]]]

Unless you specify different attributes in the command line arguments, nfxcnvrt uses the default value. You can set any of the image format characteristics to any of their allowed values. The following table lists the image format characteristics along with their allowed values and their default values:

Format characteristic | Allowed values | Default
--- | --- | ---
convert_resolution | HIGH LOW SUPER_HIGH | LOW
convert_encoding | 1D 2D MMR TIFF_S | 1D
convert_page_width | A4 B4 A3 | A4
convert_bad_line | DROP REPT TICK NONE | REPT

#### Description

The default attributes constitute image format capabilities that are found in every fax terminal. Any file processed by nfxcnvrt using its default values can be transmitted to, or received by, any fax terminal, regardless of its capabilities.

A screen message displays the number of pages processed when nfxcnvrt completes the conversion.

When you specify TIFF-S encoding, the utility converts the output file using TIFF-S attributes of 1D encoding, LOW resolution, and A4 pagewidth. TIFF-S encoding overrides any values specified on the command line.

To repair any bad lines in a file, run nfxcnvrt and specify an output format that is the same as the input format. This process removes bad lines by dropping the line, repeating the previous line, or replacing the line with a blank line and a tick mark in the margin, depending on the value selected for convert_bad_line. The original image cannot be reconstructed.
