Toucan is a Java implementation of the LifeHash hash visualization algorithm. It is a direct port of the reference C++/C implementation by Wolf McNally. Toucan requires a minimum of Java 17.
Toucan is hosted in Maven Central and can be added as a dependency with the following:
implementation('com.sparrowwallet:toucan:0.9.0')
A LifeHash is represented by the LifeHash.Image class, which can be created as follows:
import com.sparrowwallet.toucan.*;
import java.awt.image.BufferedImage;
public class Main {
public static void main(String[] args) {
LifeHash.Image lifeHashImage = LifeHash.makeFromUTF8("Hello World", LifeHashVersion.VERSION2, 1, false);
BufferedImage awtImage = LifeHash.getBufferedImage(lifeHashImage);
}
}Toucan has a small testsuite ported from the C++ implementation. The tests can be run with:
./gradlew test
