Another is Image from the National Institute of Health.  I don't think
it will do what you want, but it has many useful features.  It is free
via anonymous FTP at nih.for.image.s/w (128.231.128.7). The following is
the README file:

NIH Image
---------
NIH Image is a public domain program for the Macintosh for doing digital
image processing and analysis. It can acquire, display, edit, enhance,
analyze, print, and animate grayscale and color images.  It reads and writes
TIFF, PICT, PICS and MacPaint files It features multiple windows, 
MacPaint-like editing and 8 levels of magnification. It supports 
Data Translation and Scion frame
grabber cards. Image requires at least 4MB of RAM and 8-bit video. The
following files in the directory /pub/image contain NIH Image,
documentation, source code, and example images.

   image1xx.hqx         NIH Image 1.xx application
   image1xx_docs.hqx    Documentation in Word 4.0 format
   image1xx_source.hqx  Think Pascal 4.0 source
   image1xxNonFPU.hqx   Version that does not require a floating-point
chip
   images               Directory with images in TIFF and PICT format

NIH Image is also available from zippy.nimh.nih.gov[128.231.98.32], in
the directory /pub/image. This machine has programs and example images that
are not available on alw.nih.gov.


File Formats
------------
Files with the .hqx extension have been compressed and encoded into
BinHex format using the Mac utility Stuffit 1.5.1. The BinHex protocol
transforms binary Mac files to plain ASCII so they can reside on other
computer systems and be transferred by email. BinHex files must
be transferred to a Mac and decoded and uncompressed using Stuffit or
some other Mac file compression utility. A copy of Stuffit 1.5.1 is in
the directory /pub/util in MacBinary format.


ColorImage
----------
This is a beta version of ColorImage, which is NIH Image extended to
acquire and segment color images from RGB sources.

Giffer
------
Giffer is a shareware program useful for converting from GIF to Pict
format, and vis-versa.

ImageFFT(directory)
-------------------
ImageFFT is an extension to NIH Image to support frequency domain (power
spectrum) display and editing. It can do a 512x512 FFT in 18 seconds on
a Mac IIfx.

ImageFractal(directory)
-----------------------
ImageFractal is a version of Image modified to compute the Fractal Index
of objects by the Richardson Plot or the Tile-amalgamation methods.

NCSA PalEdit
------------
NCSA PalEdit is a public domain program from the National Center for
Supercomputing Applications for creating and customizing color palettes.
With PalEdit, you can modify the whole palette or individual entries in the
palette, to create a set of colors tailored to your needs. PalEdit can 
save palettes in three formats that are compatible with NIH Image:
PixelPaint, Canvas, and Klutz.

Switch-A-Roo
------------
Switch-A-Roo is a free Fkey that will allows you to rapidly switch
between any two monitor depths settings(e.g. 8-bit color and 24-bit color) by
pressing a few keys.

Projectionist
-------------
Projectionist is a utility that allows you to animate stacks created
by Image and saved in PICS format. Because all the frames in the
stack do not need to be loaded into RAM, Projectionist requires
less memory than image. This preliminary version uses the standard
system palette, so stacks created with Image may lose some of
their colors when animated with Projectionist.

Fetch
-----
Fetch is a slick utility that allows networked Macs to transfer files
over the Internet using the File Transfer Protocol(FTP). It does
BinHex decoding and file decompression as the files are transferred.
