Installing Plugins in ImageJ

ImageJ

Option 1

Prebuild binaries are published with each Release.

  1. Look for in the asset section for an "ijp-color_plugins_*_win.zip" file assuming you are using Windows, or "ijp-color_plugins_*_mac*.zip" for MacOS. Do now download the "Source code".
  2. Download and unzip into ImageJ's plugins directory. It should create subdirectory "ij-plugins". There should be several files with extension *.jar
  3. Restart ImageJ

Option 2 (less frequently updated)

IJP Color is also a part of the ij-plugins-bundle. You can download from its Release page.

ImageJ2/FIJI

NOTE: no recent updates with this method, due to issues with FIJI and JavaFX updates.
