ImageJ is a public domain Java image processing program inspired by NIH Image for the Macintosh. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.1 or later virtual machine. It can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit images. It can read many image formats including TIFF, GIF, JPEG, BMP, DICOM, FITS and "raw". It supports "stacks", a series of images that share a single window. It is multithreaded, so time-consuming operations such as image file reading can be performed in parallel with other operations. It can calculate area and pixel value statistics of user-defined selections. It can measure distances and angles. It can create density histograms and line profile plots. It supports standard image processing functions such as contrast manipulation, sharpening, smoothing, edge detection and median filtering. It does geometric transformations such as scaling, rotation and flips. Image can be zoomed up to 32:1 and down to 1:32. All analysis and processing functions are available at any magnification factor. The program supports any number of windows (images) simultaneously, limited only by available memory. Spatial calibration is available to provide real world dimensional measurements in units such as millimeters. Density or gray scale calibration is also available.
What's new in this version:
- Michael Schmid extended the HTMLDialog class to support more text (wrapping lines, scrollbar) and hypertext links. This allows for longer GenericDialog help messages and "About this Plugin" dialogs.
- Thanks to Michael Schmid, "Live" mode z-axis profile plots and histograms are updated when you use a command in the Edit>Selection menu, such as shift-a Select None.
- Thanks to Michael Schmid, y-units and z-units are saved with and read from tiff/zip files and special ch... See all new features »
