Creazione di un nuovo documento PDF utilizzando l'API PDFBOX

Question

È necessario creare un PDF che contenga il rapporto dello stato di esecuzione, in cui lo stato si trova nella struttura della tabella. È possibile generare un formato di tabella pdf con l'API PDFBOX?

Ecco alcuni esempi di codice per la creazione di un nuovo documento PDF:

import java.awt.Color; 
import java.io.IOException; 
import org.apache.pdfbox.exceptions.COSVisitorException; 
import org.apache.pdfbox.pdmodel.PDDocument; 
import org.apache.pdfbox.pdmodel.PDPage; 
import org.apache.pdfbox.pdmodel.edit.PDPageContentStream; 
import org.apache.pdfbox.pdmodel.font.PDFont; 
import org.apache.pdfbox.pdmodel.font.PDType1Font; 



public class HelloWorld 
{ 
    /** 
    * Constructor. 
    */ 
    public HelloWorld() 
    { 
     super(); 
    } 


    public static void main(String[] args) throws IOException, COSVisitorException 
    { 
     PDDocument doc = null; 
    try 
    { 
     doc = new PDDocument(); 

     PDPage page = new PDPage(); 
     doc.addPage(page); 
     PDFont font = PDType1Font.COURIER_BOLD_OBLIQUE; 
     Color color = Color.blue; 


     PDPageContentStream contentStream = new PDPageContentStream(doc, page); 
     contentStream.beginText(); 
     contentStream.setFont(font, 12); 
     contentStream.setNonStrokingColor(color); 
     contentStream.moveTextPositionByAmount(100, 700); 
     contentStream.drawString("message"); 

     contentStream.setNonStrokingColor(Color.GREEN); 
     contentStream.drawString("Hi"); 

     contentStream.endText(); 
     contentStream.close(); 
     doc.save("d:\\abc.pdf"); 
    } 
    finally 
    { 
     if(doc != null) 
     { 
      doc.close(); 
     } 
    } 
    } 
}

Prova questo:

public static void drawTable(PDPage page, PDPageContentStream contentStream, 
          float y, float margin, 
          String[][] content) throws IOException { 
     final int rows = content.length; 
     final int cols = content[0].length; 
     final float rowHeight = 20f; 
     final float tableWidth = page.getCropBox().getWidth() - margin - margin; 
     final float tableHeight = rowHeight * rows; 
     final float colWidth = tableWidth/(float)cols; 
     final float cellMargin=5f; 

     //draw the rows 
     float nexty = y ; 
     for (int i = 0; i <= rows; i++) { 
      contentStream.drawLine(margin, nexty, margin+tableWidth, nexty); 
      nexty-= rowHeight; 
     } 

     //draw the columns 
     float nextx = margin; 
     for (int i = 0; i <= cols; i++) { 
      contentStream.drawLine(nextx, y, nextx, y-tableHeight); 
      nextx += colWidth; 
     } 

     //now add the text 
     contentStream.setFont(PDType1Font.HELVETICA_BOLD , 12); 

     float textx = margin+cellMargin; 
     float texty = y-15; 
     for(int i = 0; i < content.length; i++){ 
      for(int j = 0 ; j < content[i].length; j++){ 
       String text = content[i][j]; 
       contentStream.beginText(); 
       contentStream.moveTextPositionByAmount(textx,texty); 
       contentStream.drawString(text); 
       contentStream.endText(); 
       textx += colWidth; 
      } 
      texty-=rowHeight; 
      textx = margin+cellMargin; 
     } 
    } 

E semplicemente chiamare questo metodo in main funzione

public static void main(String[] args) throws IOException, COSVisitorException { 
    PDDocument doc = new PDDocument(); 
    PDPage page = new PDPage(); 
    doc.addPage(page); 
    PDPageContentStream contentStream = new PDPageContentStream(doc, page); 

    String[][] content = { 
     {"Name"," Time "}, 
     {"HTC","01:25"}, 
     {"Samsung Tab2","05:30"} 
    } ; 

    drawTable(page, contentStream, 700, 100, content); 

    contentStream.close(); 
    doc.save("h:\\test.pdf"); 
}

Ho appena annuncio ded un semplice wrapper per pdfBOX og github. Ha un semplice supporto di tabella che probabilmente puoi usare come base di riferimento per cut'n paste. Oppure usa la classe così com'è se vuoi. https://github.com/heksemann/HexPDF
