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.
IMAGES
This subdirectory contains several versions of a black-and-white file with the common name "Aldus", a gray file entitled "all256", and a color file called "rgb". These file names are ended with one of four suffixes; "U" for uncompressed, "LZ" for LZW compressed, "LD" for LZW compression with differencing, or "P" for palette color.
PACKBITS
This subdirectory contains the files packbits.c and unpackbits.c. These files are C source code fragments for implementing the routines necessary to compress and decompress a file under compression = 32773.
