- 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.
-
- nih-image1xx_fpu.hqx NIH Image 1.xx application. Requires FPU.
- nih-image1xx_nonfpu.hqx Version that does not require floating-point
- nih-image1xx_docs.hqx Documentation in Word 5.0 format
- nih-image1xx_source.hqx Think Pascal 4.0 source
- images Directory with images in TIFF and PICT format
- stacks Example stacks(3D images and movies) (directory)
- nih-image_spinoffs Contains variants of NIH Image(directory)
- programs Directory containing miscellaneous related programs
-
- File Formats
- ------------
- Files are in one of three formats. Those with a ".hqx" suffix are BinHex
- encoded Mac binary files, those with a ".bin" suffix are MacBinary encoded
- Mac binary files, and those with a ".txt" suffix are a plain text files. The
- BinHex and MacBinary formats represent the two parts of a Mac file(the data
- fork and the resource fork) as a single file. They permit storage of a
- complete Mac file on a non-Mac system, such as this server.
-
- Most files were compressed using the Mac utility Stuffit 1.5.1 and uploaded
- using Fetch, which does the BinHex or MacBinary encoding. Both utilities can
- be found in the util directory. The best way to retrieve files is to use
- Fetch, which automatically does Binhex (or MacBinary) decoding and file
- decompression. Unfortunately, Fetch requires a Mac directly connected to the
- Internet. If this is not the case, use an FTP (File Transfer Protocol)
- utility to transfer the files to a local host and then transfer them to a
- Mac via modem.
-
- For Macs not directly on the Internet, BinHex files must be transferred to
- a Mac using "ascii" mode and then decoded and decompressed using Stuffit or
- some other Mac compression utility, such as Compact Pro. MacBinary files
- must be transferred to an intermediate host using FTP in "binary" mode,
- then transferred to a Mac in "MacBinary" mode and decompressed using
- Stuffit or Compact Pro. A copy of Stuffit 1.5.1 is in the directory
- /pub/util in MacBinary format. The document "ftp-primer.txt" in the
- documents directory provides more information on file formats and FTP.

- NIH Image Mailing List
- ----------------------
- There is an NIH Image mailing list. It was set up by a group in the Soil
- Science Department at the University of Minnesota. To subscribe, send a
- message containing the line "subscribe nih-image <your name>" to
- soils.umn.edu.

-
- DepthGauge
- ----------
- DepthGauge is a control panel that allows rapid switching between
- monitor depths settings(e.g. 8-bit color and 24-bit color).
-
-
- Fetch(/pub/util)
- ----------------
- 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.
-
- Giffer(/pub/image/peograms)
- -----------------------
- Giffer is a shareware program useful for converting from GIF to Pict
- format, and vis-versa.
-
- ImageFFT(/pub/image/image_spinoffs)
- -----------------------------------
- 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(/pub/image/image_spinoffs)
- ---------------------------------------
- ImageFractal is a version of Image modified to compute the Fractal Index
- of objects by the Richardson Plot or the Tile-amalgamation methods.
-
- Image/MG(/pub/image/image_spinoffs)
- -----------------------------------
- Image/MG is an extension of Image supporting quantitative evaluation
- of cerebral blood flow, glucose metabolism, and protein synthesis.
-
- NCSA PalEdit(/pub/image/programs)
- -----------------------------
- 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 a format compatible with NIH Image.
-
- MockWrite
- ---------
- MockWrite is a simple DA text editor that is convenient for editing macros
- written in Image's Pascal-like macro programming language.
-
- Projectionist(/pub/image/programs)
- ------------------------------
- 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.
