Remarks
This is the first release of the g3g4 utilities. Work in progress
to enhance the capabilities of the toolkit includes table encoding
of group 3 and group 4 images, and some optimization.
A tiff toolkit is also being prepared. Although the routines in this
collection can be used with g3 and g4 images in tiff files, they
have no provision for handling the structure of the files themselves.
The future tiff toolkit will add those features.
Note that the calling sequence of the user-provided support routines
differs slightly from that indicated in the C Users Journal article.
The versions here make indirect calls using pointers, so that at
one time one input routine might be used, and at other times another.
This allows considerably more flexible usage, since the source of
the file can be changed without relinking. The names have been
changed a little to prevent inadvertent use of the old method.
