I'm testing PDFBox and I've a doubt writing a new document..
The following code writes 75 lines in a pdf file. The height of the file isn't enough. So I'd need to know when the contentStream reaches the end of page in order to create a new one and continue writing lines.
Any way to solve my question?
Thank you so much!
File pdfFile = new File("hello.pdf");
PDDocument doc = new PDDocument();
PDPage page = new PDPage();
PDPageContentStream contentStream = new PDPageContentStream(doc, page);
contentStream.setFont( PDType1Font.TIMES_ROMAN, 12);
float initPosY = page.getMediaBox().getHeight()-50;
contentStream.beginText();
contentStream.newLineAtOffset(25, initPosY);
contentStream.setLeading(30.5f);
for(int i=1; i<75;i++){
contentStream.showText("Line: "+i);
contentStream.newLine();
}
contentStream.endText();
contentStream.close();
doc.addPage(page);
doc.save(pdfFile);
doc.close();
Substract the leading value (30.5f) from initPosY in your loop after calling newLine(). When it is < 0, or below a useful value (e.g. 50 which is your top margin), then you should start a new page.
I trying to write some bengali text into a pdf with PDFBox but facing some problem No glyph for U+0053.I have no idea for glyph.
File file = new File("xyz.pdf");
PDDocument document = PDDocument.load(file);
PDPage page = document.getPage(0);
PDPageContentStream contentStream = new PDPageContentStream(document, page);
contentStream.beginText();
PDFont font = PDType0Font.load(document, BengaliPdfGenerationHelloWorld.class.getResourceAsStream("/textloc/Lohit-Bengali.ttf"),true);
contentStream.setFont(font,12);
contentStream.newLineAtOffset();
contentStream.showText(text);
contentStream.endText();
System.out.println("Content added");
contentStream.close();
document.save(new File("new.pdf"));
Exception in thread "main" java.lang.IllegalArgumentException: No glyph for U+0053 (S) in font Lohit-Bengali

I am trying to dynamically add PDF pages depending upon content size.
for that I did not want to clutter the main method, instead I created a separate method to write the PDF and call the method from main() like below:
//PDF Log Method
PDlog("Create First Page", "b");
PDlog("add more page", "b");
PDlog("close pdf", "b");
I have added system.out.println at the end of each if condition, and all three are getting printed on IDE screen. but an Empty PDF is being generated after 3 method calls end. When I had only one if condition and called the PDlog method only once, the PDF is being saved and closed properly.
How can I call this method multiple times from main and keep on adding page and content multiple times?
Below is the method code:
public static void PDlog(String action, String msg) throws IOException, ClassNotFoundException, SQLException, InterruptedException, COSVisitorException {
//Master PDF Log File --------------------------------------------------------------------
String masterPDLog = "X:\\eHub\\QA\\eHub_Automation_Log.pdf";
// Create a document and add a page to it
PDDocument document = new PDDocument();
PDPage page = new PDPage(PDPage.PAGE_SIZE_A4);
if (action.equals("Create First Page")) {
document.addPage(page);
// Create a new font object selecting one of the PDF base fonts
PDFont font = PDType1Font.TIMES_ROMAN;
PDFont boldFont = PDType1Font.TIMES_BOLD;
//File for CTS Logo --------------------
InputStream in = new FileInputStream(new File("X:\\eHub\\QA\\img\\cts.jpg"));
PDJpeg img = new PDJpeg(document, in);
// Start a new content stream which will "hold" the to be created content
PDPageContentStream contentStream = new PDPageContentStream(document, page);
//Place CTS Logo
//contentStream.drawImage(img, 500, 750);
contentStream.drawXObject( img, 450, 700, 50, 50 );
// Define a text content stream using the selected font, moving the cursor and drawing the text "Hello World"
contentStream.beginText();
contentStream.setFont( boldFont, 20 );
contentStream.setNonStrokingColor(Color.BLUE);
contentStream.moveTextPositionByAmount( 120, 650 );
contentStream.drawString("eHub Automated Data Quality Report");
contentStream.endText();
contentStream.beginText();
contentStream.setFont( boldFont, 20 );
contentStream.setNonStrokingColor(Color.BLUE);
contentStream.moveTextPositionByAmount( 140, 600 );
contentStream.drawString("Data Profiling/Quality/Analysis");
contentStream.endText();
// Make sure that the content stream is closed:
contentStream.close();
//document.save(masterPDLog);
System.out.println("1ST PAGE ADDED");
}
else if (action.equals("add more page")) {
PDFont font = PDType1Font.TIMES_ROMAN;
document.addPage(page);
PDPageContentStream contentStream = new PDPageContentStream(document, page);
contentStream.beginText();
contentStream.setFont( font, 20 );
contentStream.setNonStrokingColor(Color.BLACK);
contentStream.moveTextPositionByAmount( 100, 800 );
contentStream.drawString("eHub Automated Data Quality Report");
contentStream.endText();
contentStream.close();
//document.save(masterPDLog);
System.out.println("2ND PAGE ADDED");
}
else if (action.equals("close pdf")) {
PDFont font = PDType1Font.TIMES_ROMAN;
PDPageContentStream contentStream = new PDPageContentStream(document, page);
contentStream.beginText();
contentStream.setFont( font, 20 );
contentStream.setNonStrokingColor(Color.BLACK);
contentStream.moveTextPositionByAmount( 100, 800 );
contentStream.drawString("eHub Automated Data Quality Report");
contentStream.endText();
contentStream.close();
document.save(masterPDLog);
document.close();
System.out.println("PDF CLOSED");
}
You create the document each time, that is why.
Just pass the document object to your method, and create the document first - here's your code, corrected:
public static void main(String[] args) throws IOException, COSVisitorException
{
PDDocument document = new PDDocument();
pdlog("Create First Page", "b", document);
pdlog("add more page", "b", document);
pdlog("close pdf", "b", document);
}
public static void pdlog(String action, String msg, PDDocument document) throws IOException, COSVisitorException
{
//Master PDF Log File --------------------------------------------------------------------
String masterPDLog = "X:\\eHub\\QA\\eHub_Automation_Log.pdf";
// Create a document and add a page to it
PDPage page = new PDPage(PDPage.PAGE_SIZE_A4);
if (action.equals("Create First Page"))
{
document.addPage(page);
// Create a new font object selecting one of the PDF base fonts
PDFont font = PDType1Font.TIMES_ROMAN;
PDFont boldFont = PDType1Font.TIMES_BOLD;
//File for CTS Logo --------------------
InputStream in = new FileInputStream(new File("X:\\eHub\\QA\\img\\cts.jpg"));
PDJpeg img = new PDJpeg(document, in);
// Start a new content stream which will "hold" the to be created content
PDPageContentStream contentStream = new PDPageContentStream(document, page);
//Place CTS Logo
//contentStream.drawImage(img, 500, 750);
contentStream.drawXObject(img, 450, 700, 50, 50);
// Define a text content stream using the selected font, moving the cursor and drawing the text "Hello World"
contentStream.beginText();
contentStream.setFont(boldFont, 20);
contentStream.setNonStrokingColor(Color.BLUE);
contentStream.moveTextPositionByAmount(120, 650);
contentStream.drawString("eHub Automated Data Quality Report");
contentStream.endText();
contentStream.beginText();
contentStream.setFont(boldFont, 20);
contentStream.setNonStrokingColor(Color.BLUE);
contentStream.moveTextPositionByAmount(140, 600);
contentStream.drawString("Data Profiling/Quality/Analysis");
contentStream.endText();
// Make sure that the content stream is closed:
contentStream.close();
//document.save(masterPDLog);
System.out.println("1ST PAGE ADDED");
}
else if (action.equals("add more page"))
{
PDFont font = PDType1Font.TIMES_ROMAN;
document.addPage(page);
PDPageContentStream contentStream = new PDPageContentStream(document, page);
contentStream.beginText();
contentStream.setFont(font, 20);
contentStream.setNonStrokingColor(Color.BLACK);
contentStream.moveTextPositionByAmount(100, 800);
contentStream.drawString("eHub Automated Data Quality Report");
contentStream.endText();
contentStream.close();
//document.save(masterPDLog);
System.out.println("2ND PAGE ADDED");
}
else if (action.equals("close pdf"))
{
PDFont font = PDType1Font.TIMES_ROMAN;
PDPageContentStream contentStream = new PDPageContentStream(document, page);
contentStream.beginText();
contentStream.setFont(font, 20);
contentStream.setNonStrokingColor(Color.BLACK);
contentStream.moveTextPositionByAmount(100, 800);
contentStream.drawString("eHub Automated Data Quality Report");
contentStream.endText();
contentStream.close();
document.save(masterPDLog);
document.close();
System.out.println("PDF CLOSED");
}
}
Your "close pdf" action does not make much sense, you are writing to a PDPage that is never appended.
1st of all, thanks Tilman for answering my actual question.
In the meantime, for practical purposes, I have changed my approach to writing dynamically to a PDF, as the code flows through If Else and Loops.... instead I have chosen to simply keep on Logging to simple text file using PrintWriter.
At the final end of the code, I am calling a method to Read each line of the Text Log file and place in a PDF document. To Summarize: One time Text to PDF conversion.
I explored iText and chose it over Apache PDFBox, it is perhaps 2-3 times faster than PDFBox and adding page is implicit and automatic.
I've been using PDFBox in an attempt to spit out an auto-generated PDF based off an existing template. The code below fails at finalDoc.save() with an IndexOutOfBoundsException and I'm not sure what I'm doing wrong.
PDDocument finalDoc = new PDDocument();
for (StudentEN student : students) {
PDDocument document = PDDocument.load("template.pdf");
PDPage page = (PDPage) document.getDocumentCatalog().getAllPages().get(0);
PDPageContentStream contentStream = new PDPageContentStream(document, page, true, true);
contentStream.beginText();
// Draw stuff
contentStream.endText();
contentStream.close();
finalDoc.addPage(page);
document.close();
}
finalDoc.save(response.getOutputStream());
finalDoc.close();
Any help is greatly appreciated!
PDFMergerUtility did the job for me:
PDFMergerUtility finalDoc = new PDFMergerUtility();
for (StudentEN student : students) {
PDDocument document = PDDocument.load("template.pdf");
PDPage page = (PDPage) document.getDocumentCatalog().getAllPages().get(0);
PDPageContentStream contentStream = new PDPageContentStream(document, page, true, true);
contentStream.beginText();
// Draw stuff
contentStream.endText();
contentStream.close();
ByteArrayOutputStream out = new ByteArrayOutputStream();
document.save(out);
finalDoc.addSource(new ByteArrayInputStream(out.toByteArray()));
document.close();
}
response.setContentType("application/pdf");
finalDoc.setDestinationStream(response.getOutputStream());
finalDoc.mergeDocuments();
I am trying to create a PDF file with a lot of text boxes in the document and textfields from another class. I am using PDFBox.
OK, creating a new file is easy and writing one line of text is easy. Now, when I am trying to insert the next text line or textfield, it overwrites the content.
PDDocument doc = null;
PDPage page = null;
try{
doc = new PDDocument();
page = new PDPage();
doc.addPage(page);
PDFont font = PDType1Font.HELVETICA_BOLD;
PDPageContentStream title = new PDPageContentStream(doc, page);
title.beginText();
title.setFont( font, 14 );
title.moveTextPositionByAmount( 230, 720 );
title.drawString("DISPATCH SUMMARY");
title.endText();
title.close();
PDPageContentStream title1 = new PDPageContentStream(doc, page);
title1.beginText();
title1.setFont( font, 11 );
title1.moveTextPositionByAmount( 30, 620 );
title1.drawString("DEPARTURE");
title1.endText();
title1.close();
doc.save("PDFWithText.pdf");
doc.close();
} catch (Exception e){
System.out.println(e);
}
It does give me an error: "You are overwriting an existing content, you should use the append mode".
So I am trying title1.appendRawCommands(String), but it is not working.
How would I add new text boxes and textfields (from another class)? I have read tens of tutorials on Internet, but they only show creating one line.
PDPageContentStream title1 = new PDPageContentStream(doc, page, true, true);
OP posted this as the answer, so this will flag to the system that there was an answer
Furthermore, if the first content stream contains operations substantially changing the graphics state, e.g. by changing the current transformation matrix, and one wants the new content stream to start with these changes reverted, one should use the constructor with three boolean parameters:
PDPageContentStream title1 = new PDPageContentStream(doc, page, true, true, true);
This implementation is deprecated.
PDPageContentStream title1 = new PDPageContentStream(doc, page, true, true);
The new implementation would be
PDPageContentStream title1 = new PDPageContentStream(doc, page, PDPageContentStream.AppendMode.OVERWRITE, true);
