- Runs Everywhere:
- ImageJ is written in Java, which allows it to run on Linux,
Mac OS X and Windows, in both 32-bit and 64-bit modes.
- Open Source:
- ImageJ and its
Java source code
are freely available and in the
No license is required.
- User Community:
- ImageJ has a large and knowledgeable worldwide user community. More than 1700 users and developers
subscribe to the
ImageJ mailing list.
- Automate tasks and create custom tools using
Generate macro code using the
and debug it using the
More than 300 macros
on the ImageJ Web site.
- Extend ImageJ by developing plugins using ImageJ's built in text editor and
Java compiler. More than 500 plugins are available.
- Use ImageJ as a image processing toolkit (class library) to develop
applets, servlets or applications.
- 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!
- Data Types:
- 8-bit grayscale or indexed color, 16-bit unsigned integer, 32-bit floating-point
and RGB color.
- File Formats:
- Open and save all supported data types as TIFF (uncompressed) or as raw data.
Open and save GIF, JPEG, BMP, PNG, PGM, FITS and ASCII. Open DICOM.
Open TIFFs, GIFs, JPEGs, DICOMs and raw data using a URL. Open and save
many other formats using
- Image display:
- 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 selections and automatically create them using the wand tool.
Draw, fill, clear, filter or measure selections.
Save selections and transfer them to other images.
- Image Enhancement:
- 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.
- Geometric Operations:
- 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.
- Color Processing:
- 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.
