The PC TIFF TOOLS diskette is made up of the the following:


TIFFDUM4

This subdirectory contains the source for a C utility that dumps the TIFF image file header data. The header information provides details on the tag structure that are useful for analyzing TIFF images. In addition, this version of the TIFF dump utility, tiffdum4, supplies warnings if the tag values do not conform to the recommended parameters. To run this application, enter the program name (tiffdum4) followed by the fully qualified name of the file to be dumped. To redirect output from the screen and into a file, add ">" and a name for the output file. This program does recognize path names.


TIFFSWAP

The TIFFSWAP subdirectory contains the C source for a simple byte-swapping utility that will reverse the order of bytes between Motorola and Intel formats. To run this application
enter the program name (tiffswap) followed by the fully qualified name of the file to be converted. You may use this program as is, incorporate or build on the algorithm for your own purposes.
