![]() The second example is inspired by atomic resolution images recorded with an Transmission Electron Microscope (TEM). Purpose of the single underscore _ variable.Top-level script environment ( _main_).** (double star) and * (star) parameters.The following list links to documentation of the used Python features: It is recommended to copy the code to the Script Editor and run it by yourself. Finally the names of the selected images are printed to the Log window. This example script will create up to 10 new images and create a GenericDialog to select 3 of them. Image selection using the GenericDialog class log ( "This is a string followed by an int " + str ( 10 ))Ĭontrary to the print statement the log function display some output into a log window (newly open if not already open), and accept only a string as argument. Jython basics for ImageJįrom ij import IJ IJ. Hopefully the examples on this page can convince you of that. It is not possible to use external python modules (like Numpy…) however, any Java class residing in the Fiji installation can be used.Įven with the given limitations, Jython is a powerful language for ImageJ scripting. The Java implementation of Python is limited to the standard library of Python 2. Have a look at the examples on this page and decide if you want to start using Python for ImageJ scripting. In Python, many problems can be solved with less code than in other languages.If your only aim is to write scripts for ImageJ, there are other languages you should try first (e.g. If don’t have any experience in programming, the Python language is a good choice to start with.By building your own modules you can create complex scripts that otherwise are only possible by writing ImageJ plugins in Java. But you have to keep in mind that tools commonly used in many Python projects (e.g. If you have experience with Python, you can easily use Jython for ImageJ scripting.The following list will help you to decide if Jython is the right choice to create scripts for ImageJ: ![]() Jython has a syntax that differs from most other language as indentations instead of brackets are used to group code blocks. ![]() There are only differences in how the imports are handled and in the syntax of the selected language. When to use JythonĪll scripting language supported by ImageJ can be used to access the ImageJ API. 1 In ImageJ, Jython is one of several supported languages. Jython is an implementation of the Python programming language designed to run on the Java platform. To call ImageJ functionsįrom Python programs, see PyImageJ.
