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

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.

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"

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.

Full Specifications

What's new in version 1.50f
  • Added the Analyze>Tools>Grid command, which creates a non-destructive grid of lines, crosses, circles or points on the current image.
  • Thanks to Michael Elbaum, added the Process>FFT>Make Circular Selection command.
  • Thanks to Daniel Chung, text images can now be opened by dragging and dropping them on the ">>" icon in the toolbar.
  • Thanks to Stein Rorvik, with spatially calibrated images, the raw width and height are shown in parenthesis as a selection is being created.
  • Thanks to Sho Fujisawa, the ROI Manager uses 5 digits for y-coordinates in ROI names if the image height is greater than 9999 pixels.
  • Thanks to Norbert Vischer, added the Stack.setOrthoViews(x,y,z), Stack.getOrthoViewsID() and Stack.stopOrthoViews() macro functions.
  • Thanks to Stein Rorvik, added the getInfo("macro.filepath") macro function.
  • Thanks to Norbert Vischer, Image>Stacks>Orthoganal Views is faster and more reliable when working with hyperstacks.
  • The getInfo(key) macro function returns "Invalid key" if a value associated with the key is not found.
  • Thanks to Gabriel Landini, added the ImageProcessor.drawLine4(x1,y1,x2,y2) method, which draws 4-connected lines.
  • Added the static RoiManager.getRoiManager() method, which returns a reference to the ROI Manager and opens the "ROI Manager" window if it is not already open.
  • Thanks to Nicolas Stifani, fixed bugs that could cause the getResultLabel(row) and getResultString("Label",row) macro functions to fail.
  • Thanks to MartinH, fixed a bug that caused montages created using Image>Stacks>Make Montage to lose their pixel dimensions.
  • Thanks to Norbert Vischer, fixed a bug that caused the Pixel Inspector tool to not work correctly with blank 32-bit images.
  • Thanks Kees Straatman, fixed a bug that caused Process>Find Maxima, with "Count" output, to sometimes display unwanted results.
  • Thanks to Romain Guiet, fixed a bug in the ROI Manager that caused it to ignore an ROI name if the name was 9 character in length and it had a "-" in the middle.
  • Thanks to Stein Rorvik, fixed a bug that caused macros run from the command line to fail if the argument contained parenthesis.
  • Fixed a 1.50c regression that caused the deprecated RoiManager.getROIs() method to return null.
