ImageJ runs on Linux, Mac OS 9, Mac OS X, Windows, and the Sharp Zaurus PDA.
ImageJ and its Java source code are freely available and in the public domain. No license is required.
ImageJ has a large and knowledgeable worldwide user community. More than 1400 users and developers subscribe to the ImageJ mailing list.
8-bit grayscale or indexed color, 16-bit unsigned integer, 32-bit floating-point and 32-bit RGB color.
Open and save all supported data types as TIFF (uncompressed) or as raw data. Open and save GIF, JPEG, BMP and ASCII. Open DICOM, FITS, PNG and PGM. Open TIFFs, GIFs, JPEGs, DICOMs and raw data using a URL. Open and save many other formats using plugins.
ImageJ is the world's fastest pure Java image processing program. It can filter a 2048x2048 image in 0.1 seconds (*). That's 40 million pixels per second!
Automate tasks and create custom tools using macros. Automatically generate macro code using the command recorder. More than 200 macros are available on the ImageJ Web site.
Extend ImageJ by developing plugins using ImageJ's built in text editor and Java compiler. More than 300 plugins are available.
Use ImageJ as a image processing toolkit (class library) to develop applets, servlets or applications.
Tools are provided for zooming (1:32 to 32:1) and scrolling images. All analysis and processing functions work at any magnification factor.
Create rectangular, elliptical or irregular area selections. Create line and point selections. Edit selectoins and automatically create them using the wand tool. Draw, fill, clear, filter or measure selections. Save selections and transer them to other images.
Supports smoothing, sharpening, edge detection, median filtering and thresholding on both 8-bit grayscale and RGB color images. Interactively adjust brightness and contrast of 8, 16 and 32-bit images.
Crop, scale, resize and rotate. Flip vertically or horizontally.
Measure area, mean, standard deviation, min and max of selection or entire image. Measure lengths and angles. Use real world measurement units such as millimeters. Calibrate using density standards. Generate histograms and profile plots.
Cut, copy or paste images or selections. Paste using AND, OR, XOR or "Blend" modes. Add text, arrows, rectangles, ellipses or polygons to images.
Split a 32-bit color image into RGB or HSV components. Merge 8-bit components into a color image. Convert an RGB image to 8-bit indexed color. Apply pseudo-color palettes to grayscale images.
Display a "stack" of related images in a single window. Process an entire stack using a single command. Open a folder of images as a stack. Save stacks as multi-image TIFF files.
