Here is the snippet of code that produces the error. The macro code can be modied in the built-in editor. Plugins are implemented as Java classes, which means that you can use all features of the Java language, access the full ImageJ API and use all standard and third-party Java APIs in a plugin. Just to be clear: there are approximately 40 named points and 3 or 4 of them must be selected to make 2. Plugins are a much more powerful concept than macros and most of ImageJ’s built-in menu commands are in fact implemented as plugins. The simplest way to create a macro is to call using Plugins/Macros/Record and execute the commands to be recorded. Here is a quick example for the single point tool: newImage ('Example', '8-bit noise', 100, 100, 1) makePoint (40, 60) getSelectionCoordinates (x,y) Array.show (x,y) Hope that helps In both cases there are plenty of disadvantages. A problem with writing a macro code for using calculator plus pluging, divide operation in image J. I’m running on a Mac OS X Yosemite 10.10.5: ImageJ 2.0.0-rc-61/1.51n Java 1.8.0_66 you for replying. Macros are an easy way to execute a series of ImageJ commands. Run("Enhance Contrast", "saturated=0.35") ImageJ has a wide range of features, including: support for a wide range of image formats an integrated macro language plugin support and a comprehensive set of image processing and analysis functions. can also uncomment 3 lines below - to test with ROI Fiji is a free and open source image processing software developed by the Fiji team. SelectWindow("C3-Rat_Hippocampal_Neuron.tif") (Did any of this functionality change for images other than 8-bit I just did my own ‘dumbie’ test (too - note that I might be mis-interpreting the real issue you are encountering here) - I got the changes to pixel values after running the following code example on a 16-bit test image ( File > Open Samples > Neuron (1.6M, 5 channels)): run("Neuron (1.6M, 5 channels)") This is the only B&C option that alters the pixel data of non-RGB images. Core concepts such as variables, for-loops, and. This option currently only works with 8-bit images, 8-bit stacks and RGB stacks. The reader is expected to have some pre-existing knowledge of ImageJ Macro programming. If there is a selection, only pixels within the selection are modified. Would you be able to post a snippet of your code and perhaps an image as a test example? Just so we can see if we can recreate the same error… and what was the exact error message? Is it that you were NOT expecting pixel changes because (as per the User Guide):Īpply Applies the current display range mapping function to the pixel data. To the Forum !!! And thanks for pointing you here …
