"Great application - if you know how to use it."

August 24, 2010  |  By gordonpritchard

The app works great but the documentation sucks. I'd like to see more info about how to accomplish tasks rather than just the basics of how a tool works. For example, I'd like to measure the perimeter of halftone dots (i.e. a repeating pattern). I've figured out how to measure the perimeter of an individual do - but not multiple dots within the same image. The documentation is no help.

"ImageJ is great"

We have been using it for years at my University. Keeping in mind the price, and the collaborative method used to develop it, I think it is an awesome product. It is very versatile, and we use if for electron microscopy, astronomical images, and everything in between. It is mostly designed for medical/biology uses though.

"No 16-bit Support"

This is a nice program and it is FREE, but the fact that it doesn't support 16-bit files makes it less than a 5-star effort.

"Worthy Successor"

July 23, 2003  |  By blanford

This program is amazing and is a worthy successor to the Mac-only NIH image. On our tight budget, we get high-quality image processing tools for free. The incorporation of the FFT filters into the main distribution was a big step forward: I never boot up Classic any more to use NIH Image.

The interface is not very Mac-like and is annoying, probably due to the cross-platform nature of the code. For heavy duty image processing (multiple FFTs or volume rendering), the program runs pretty slowly. I don't expect the speed to improve, but the features keep getting more numerous (but it doesn't feel bloated) and the bugs are rapidly addressed.

What's new in version 1.49p

- Stacks open and save in less time due to faster IJ.showStatus() method.
- Added the Image>Type>Lab Stack command, which converts an RGB image into a L*a*b* stack using code from Duane Schwartzwald's Color Space Converter plugin.
- Thanks to Ferdinando Pucci, the Image>Stacks>Tools>Concatenate command works with images that differ in width or height.
- The Image>Overlay>To ROI Manager command starts numbering at 1 instead of 0.
- Thanks to Curtis Rueden, Image>Stacks>Images to Stack suggest using Image>Stacks>Tools>Concatenate if the user attempts to combine two or more stacks.
- The IJ.showStatus() method is up to a 1000 times faster (example).
- ImageJ displays a better error message when attempting to run a plugin with a missing library.
- Added the getList("image.titles") macro function.
- Thanks to Norbert Vischer, added the Roi.setPolygonSplineAnchors(), Roi.setPolylineSplineAnchors() and Roi.getSplineAnchors() macro functions (example).
- Thanks to Philippe Carl, added the RoiManager.isSelected() method (JavaScript example).
- Thanks to Philippe Carl, fixed a bug that caused plugins using the NonBlockingGenericDialog to hang when they were called using the run() macro function.
- Thanks to Matt Jackson, fixed a bug that caused the Image>Zoom>To Selection command to sometimes not work as expected (window does not expand) when the alt key is down.
- Thanks to Analia Lourenco, fixed a bug that caused ROI Manager outlines created by the particle analyzer to not be displayed in batch mode macros.
- Thanks to Neil Fazel, fixed a bug that caused File>Import>Text Image to not correctly open files containing "nan" (lower case "NaN") values.
- Thanks to Philippe Carl, fixed a bug that caused the Edit>Selection>Restore Selection command to not work as expected after making a selection in the ROI Manager.
- Thanks to Ilan Tal, fixed a bug that could cause the "Close All" command to throw an exception and cause ImageJ to hang.
- Thanks to Leon Espinosa, fixed a 1.49k regression in the behavior, when processing stacks, of the Process>Binary>Convert to Mask command and "Threshold" widget's "Apply" option.
- Thanks to Philippe Carl, fixed a regression that caused the ROI Manager's "Show All" and "Labels" buttons to not be recorded.
