Welcome to the image alignment extension for QuPath!
This was previously the Interactive image alignment command in QuPath v0.2. Not much loved by its creator, this command has proven useful to numerous people on the Scientific Community Image Forum.
It has been separated out to its own repository so that it can be developed independently from the main QuPath project. And perhaps so someone will fork it and make a better version.
To install the Align extension, download the latest qupath-extension-align-[version].jar file from releases and drag it onto the main QuPath window.
If you haven't installed any extensions before, you'll be prompted to select a QuPath user directory. The extension will then be copied to a location inside that directory.
You might then need to restart QuPath (but not your computer).
You can build the extension from source with
gradlew clean buildThe output .jar will be under build/libs.
