The home of NIH Image is thru anonymous ftp to zippy.nimh.nih.gov 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 " 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.
