我一直在寻找一个在Java应用程序中创建标签云的库,我找到了OpenCloud。
我不想使用Web服务器,OpenCloud将要求输出,不是吗?有没有办法让OpenCloud在Java / Swing面板中工作?我想要一个独立的应用程序的东西。如果这不可能,我还能在哪里寻找这样的API?

实际上,OpenCloud不需要Web服务器。只需使用Swing呈现而不是HTML / JSP。这是一个小片段,演示了使用OpenCloud库的非常基本的Swing标签云。它可以改进,但它给你的要点:
import java.util.Random;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
import org.mcavallo.opencloud.Cloud;
import org.mcavallo.opencloud.Tag;
public class TestOpenCloud {
private static final String[] WORDS = { "art", "australia", "baby", "beach", "birthday", "blue", "bw", "california", "canada", "canon",
"cat", "chicago", "china", "christmas", "city", "dog", "england", "europe", "family", "festival", "flower", "flowers", "food",
"france", "friends", "fun", "germany", "holiday", "india", "italy", "japan", "london", "me", "mexico", "music", "nature",
"new", "newyork", "night", "nikon", "nyc", "paris", "park", "party", "people", "portrait", "sanfrancisco", "sky", "snow",
"spain", "summer", "sunset", "taiwan", "tokyo", "travel", "trip", "uk", "usa", "vacation", "water", "wedding" };
protected void initUI() {
JFrame frame = new JFrame(TestOpenCloud.class.getSimpleName());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
Cloud cloud = new Cloud();
Random random = new Random();
for (String s : WORDS) {
for (int i = random.nextInt(50); i > 0; i--) {
cloud.addTag(s);
}
}
for (Tag tag : cloud.tags()) {
final JLabel label = new JLabel(tag.getName());
label.setOpaque(false);
label.setFont(label.getFont().deriveFont((float) tag.getWeight() * 10));
panel.add(label);
}
frame.add(panel);
frame.setSize(800, 600);
frame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
new TestOpenCloud().initUI();
}
});
}
}
此代码基于OpenCloud library

我用Java创建了云库,Kumo(日语云)。奇怪的是,我总是喜欢文字云。 :)
Kumo可以生成BufferedImages,图像文件(PNG,BMP等),还有显示JPanels用法的示例。该项目在mavenized和Maven Central中进行了整合,使集成变得更加容易。以下是一些示例单词云,Kumo的GitHub页面上有更多示例:https://github.com/kennycason/kumo

我使用openCloud创建简单的java字云,使用字频和/或可能性值来调整单词权重(字体大小)。云使用随机颜色并提供简单的随机旋转。
