	imconv		Convert between all supported image file formats
	imcopy		Copy a portion of an image into a new file
	imfile		Display image attributes
	imfill		Fill a region of an image with a color or gradient
	imflip		Flip an image horizontally or vertically

The SDSC Image Tools are released in binary form for the following UNIX
machine architectures:

Additional architectures are forthcomming.

The SDSC Image Tools are available for uploading via anonymous ftp from
'ftp.sdsc.edu'.  The anonymous ftp directory tree is structured by
machine architecture, and then by topic.  For instance, to get the SDSC Image
Tools for a Sun 4, use:

	ftp> cd sdscpub
	ftp> cd sun4
	ftp> cd graphics
		or
	ftp> cd [.sdscpub.sun4.graphics]

	ftp> type binary
	ftp> get IMTOOLS_V2_1_TAR.Z imtools_v2_1.tar.Z

For most architectures, software is bundled in both tar and cpio format and
compressed using the UNIX 'compress' utility.

Tool binaries, object library, release notes, and tool and library man pages
(nroff source, post-nroff text, and PostScript) are included.  Tool source
code is included.  Library source is not provided except for sample source
illustraiting how to add support for additional site-specific image file
formats.

00README's and 00INDEX's in the ftp directories explain their contents.
To get one of these, use:

	ftp> get 00README 00README
	ftp> get 00INDEX 00INDEX
