How2：將JPanel添加到文檔，然後導出爲PDF

有史以來第一次在任何論壇上編程...我通常只是搜索，直到我找到答案...但這次我真的堅持...How2：將JPanel添加到文檔，然後導出爲PDF

這裏的問題... 我有一個JPanel，而最近發現的iText爲您提供了一種Java GUI中導出爲PDF ...

我似乎無法理解的iText的語言，也不瞭解如何加入簡單的JPanel文件，然後將該文件導出爲PDF ...這是我目前所有的...

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); 
    } 
}

請請幫助...我試圖使代碼儘可能短，以避免無用的東西......提前

感謝... 克雷格

我將不勝感激代碼。提前致謝。 – Boro 2011-02-11 18:59:56

確定什麼，我所做的就是添加全班文檔中，我使用的導出爲PDF ...它非常簡單的代碼感覺它只是將整個面板導出爲Graphics2D圖像，然後也是PDF ... im s直到工作，因爲我打算出口文件作爲FDF PDF ...但現在這個文件出口罰款...

這裏是：如果你需要幫助，我會更願意協助您：

它的代碼很多，但是它很容易...只是一大堆簡單的東西......我不是最先進的程序員...... 反正......還是讓我知道，如果你需要幫助Boro

你需要調用面板上print和指定PDF格式的圖形打印到，如下圖所示：

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(); 
    } 
}

我相信你在調用`document.close（）`之前還需要調用`writer.setPageEmpty（false）`。 iText不喜歡空白頁面。 – 2010-12-23 18:37:28

How2：將JPanel添加到文檔，然後導出爲PDF
