A fundamental benefit to creating scripts and macros in ImageJ is the ability to reuse their functionality on more than one image. Although this can be done manually, there are multiple ways to easily automate this batch processing.
- Create a basic macro/script which operates on the active image or on a single file.
- Apply your macro to a group of images.
- These images do not need to be open in ImageJ already—they will be read in as part of the batch process.
- See below for details.
Option 1 - ▶ ▶
The fastest way to start batch conversion is via the ▶ ▶ command. This will open a dialog (below) that will allow you to specify an input and output directory. You can select an output file format, and then use the
Add Macro Code drop-down to generate a macro with the desired functionality.
Option 2 - Script Template
Open the script editor, select . This will generate the following boilerplate: ▶ ▶ ▶
Lines 26 and 27 can now be edited, replaced with the functional macro code you would like to apply to all images of a given type in a folder. Furthermore you can now modify the batch processing logic itself, for example if you need to customize what (if any) output information is saved.
Option 3 - Batch Processing with Script Parameters
