Dear discuss-lfm members, (apologies for any formatting glitches!) Two more essential URL's for those of you interested in=20 using NIH imaging software... 1) http://www.cipe.com THE CENTER FOR IMAGE PROCESSING IN EDUCATION promotes the use of digital image processing as a tool for teaching and learning. CIPE offers workshops and materials developed by the Image Processing for Teaching project at the University of Arizona. Image processing is the analysis of pictures on a computer screen. Using the public domain image processing software, NIH Image, digital images are displayed and manipulated in a variety of ways. Scientists have used image processing to make measurements and create visualizations from image data for many years. Now, students can use the same techniques to learn concepts in science, mathematics, and technology. and=20 2) http://ipt.lpl.arizona.edu The Image Processing for Teaching (IPT) project has made a powerful=20 new technology available as a learning tool. Students are given the=20 tools to analyze and enhance digital imagery from every field of science, mathematics, and technology. They are empowered with=20 open-ended opportunities for exploration, discovery, and quantitative analysis. Find out how your school can get involved in this exciting program.=20 Learn about opportunities for professional development, and availability=20 of curriculum-based materials. We invite you to become part of the strong national community of IPT educators.=20 REGARDING THE ISSUE OF NIH FOR DOS/WINDOWS.... THIS FILE FOUND AT THE CIPE WEB SITE: Cross-platform Issues: Using NIH Image on a PC=20 News on using NIH Image and Image Processing for Teaching activities=20 with Windows based PCs. Updated Wednesday, November 20, 1996 Since its creation, NIH Image has been a Macintosh-only software program. But, DOS and Windows aficionados can now take advantage of this powerful and easy to use program. Currently, the best option available for IBM-PC users is to run the Macintosh=AE version of NIH Image on an IBM-PC using Executor=AE 2. Executor 2 is a Macintosh emulator available from Abacus Research and Development Incorporated (ARDI). Executor 2 turns a PC into a Macintosh, allowing the user to run NIH Image and read Macintosh formatted floppies, CD-ROMs (including IPT and HIP products), ZIP disks, and other media. Executor 2 can be used on computers running DOS, Windows=AE 3.x, Windows=AE 95, and Windows=AE NT. =20 NIH Image runs nearly as well on an Executor/PC combo as it does on a Power Macintosh. On faster PC's (late model 486's and Pentiums), the NIH Image/Executor team loads images quickly and performs complicated image processing tasks at an impressive rate. Once installed and running, Executor affords the look and feel of the Apple=AE hardware platform. The program works so well that CIPE has held basic image processing workshops on Pentium computers in two college laboratories. Executor 2 has some limitations, however. First, Executor 2 is not a multi-tasking program. Accordingly, the user may only load one software program at a time. Second, Macintosh files must be stored in special DOS archives rather than directly on the PC hard drive. Third, color images often pick up muddy blotches when displayed in NIH Image under Executor. And, fourth, selections (rectangular, oval, free-form and other selections) do not display as well in the Executor/NIH Image environment as they do on a Macintosh. =20 Regardless of its limitations, Executor is a wonderful program that permits sophisticated NIH Image processing on IBM PC's. Visit ARDI to download a fully functional, 10 minute demonstration version of the program, available free of cost. In short order, however, Scion Image for Windows will be the alternative of choice for image processors using Windows 95 or Windows NT as their operating system. Image for Windows is a 32-bit program that has the look and feel of its Macintosh parent and promises to afford the same image processing power. The Scion Corporation, a manufacturer of video frame-grabbing cards, is developing the new program and plans to maintain Image for Windows as freeware.=20 =20 Development of Image for Windows is moving along well and many functions typically used by IPTer's are currently implemented. For example, most of the measurement tools and measurement functions are fully usable. Color tables can be changed and manipulated. Filtering and other image manipulation tools are also available. And, images can be stacked and animated. However, the most recent test release (Alpha 8, see screen shot =20 at right) is not yet a fully operational program. A number of=20 functions are yet to be enabled and the program contains quirks=20 and bugs that must be ironed out as the program matures. If you=20 choose to download Image for Windows from its Web site, be sure to=20 review the included README file. It describes which features=20 have been implemented in the test program and which features=20 have not been implemented.=20 =20 When Image for Windows has become a fully functioning program, two software programs available from Dataviz=AE, Macopener for WindowsTM and Conversions Plus for WindowsTM,=20 will be useful items for people who wish to use their Macintosh formatted materials from the Center for Image Processing and the Image Processing for Teaching project. Macopener allows the user to read and write Macintosh floppies and other media on an IBM-compatible PC. Conversions Plus includes Macopener within its shell and adds the ability to convert between Macintosh and IBM-PC file formats. Visit the Dataviz website for more information on their products.
