How2: Add a JPanel to a Document then export to PDF
提问by
first post ever in any forum with regard to programming... i usually just search until i find the answer... but this time im really stuck...
在任何论坛上的第一篇关于编程的帖子......我通常只是搜索直到我找到答案......但这次我真的卡住了......
here's the problem... i have a JPanel, and recently discovered that itext provides you with a way to export Java GUI to PDF...
问题来了……我有一个 JPanel，最近发现 itext 为您提供了一种将 Java GUI 导出为 PDF 的方法……
i cant seem to understand itext's language nor how to add a simple JPanel to a document then export that document to a PDF... this is all i have at the moment...
我似乎无法理解 itext 的语言，也无法理解如何将简单的 JPanel 添加到文档然后将该文档导出为 PDF ……这就是我目前所拥有的……
import java.io.FileOutputStream;
import com.itextpdf.text.*;
import com.itextpdf.text.pdf.*;
import java.awt.Color;
import javax.swing.*;
public class HelloWorld {
public static void main(String[] args) {
try
{
//Panel creation and setup
JPanel panel = new JPanel();
//just to ensure that the panel has content...
JLabel label = new JLabel("i am a label");
panel.add(label);
panel.setSize(100,100);
//so that even if the label doesnt get added...
//i can see that the panel does
panel.setBackground(Color.red);
//my understanding of the code below: the virtual document
Document document = new Document();
//my interpretation just writes the virtual pdf document to the hdd
PdfWriter writer = PdfWriter.getInstance
(document, new FileOutputStream("C:/test.pdf"));
//begin editing the vpdf
document.open();
//i wanna do something like this
//document.add(panel);
//end editing the vpdf
document.close();
} catch (Exception e)
{
System.out.println(e);
}
}
please please help... i tried to make the code as short as possible to avoid useless stuff...
请帮忙...我试图使代码尽可能短以避免无用的东西...
thanks in advance... Craig

ok what i've done is add the WHOLE class document for the code in which i used the export to PDF... its very simple in the sense that it just exports the WHOLE panel as a Graphics2D image then that too PDF... im still working on it as i intend to export the document as a FDF PDF... but for now this document exports fine...
好的，我所做的是为我使用导出到 PDF 的代码添加整个类文档......它非常简单，因为它只是将整个面板导出为 Graphics2D 图像然后也是 PDF......我仍在研究它，因为我打算将文档导出为 FDF PDF...但现在该文档导出正常...
here it is: if you need help, i'll be more than willing to assist you:
在这里：如果您需要帮助，我将非常愿意为您提供帮助：

回答by dogbane
You need to call printon the panel and specify the pdf's graphics to print to, as shown below:
您需要print在面板上调用并指定要打印到的pdf图形，如下所示：
JPanel panel = new JPanel();
//just to ensure that the panel has content...
JLabel label = new JLabel("i am a label");
panel.add(label);
panel.setSize(100,100);
//so that even if the label doesnt get added...
//i can see that the panel does
panel.setBackground(Color.red);
//the frame containing the panel
JFrame f = new JFrame();
f.add(panel);
f.setVisible(true);
f.setSize(100,100);
//print the panel to pdf
Document document = new Document();
try {
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("C:\temp\test.pdf"));
document.open();
PdfContentByte contentByte = writer.getDirectContent();
PdfTemplate template = contentByte.createTemplate(500, 500);
Graphics2D g2 = template.createGraphics(500, 500);
panel.print(g2);
g2.dispose();
contentByte.addTemplate(template, 30, 300);
} catch (Exception e) {
e.printStackTrace();
}
finally{
if(document.isOpen()){
document.close();
}
}
