I am working in LARAVEL 6.8.
I worknig on to generate New PDF which uses existing PDF as a background template.
I have tried FPDF & FPDI packages but I couldn't find a way to add data in it.
Below is the code which I have tried but this simple code also gives back the empty pdf.
$pdf = new \setasign\Fpdi\Fpdi();
$pdf->AddPage();
$pdf->setSourceFile('existingPDFfile.pdf'); <--- This PDF has a header and footer already in it.
$tplIdx = $pdf->importPage(1);
$pdf->useTemplate($tplIdx, 10, 10, 200);
$pdf->SetFont('Arial');
$pdf->SetTextColor(255,0,0);
$pdf->SetXY(50, 50);
$pdf->Write(0, "Ajay Patel");
$pdf->Output('D','test.pdf', "F");
In further, I need to use this existing PDF as a template and want to add new data in the body of pdf and generate new pdf from it which has a background of this "Template PDF".
I hope i have explained myself.

I am developing an Android app for flight reservation and i am using firebase Database for storing and retriving data. I need to generate a PDF of Ticket and contents should be changed as per passenger details and stored in local directory. I have a template of Ticket. What should i do?
Thank you in advance.
Since Android 5 you can use PdfDocument and its friend classes to generate a PDF document on Android device. The official documentation is here. There is no library to use a template with PdfDocument. You have to use some drawing primitive to accomplish your task.
Here is a sample to generate a PDF with a single page A4:
// create a new document
PdfDocument document = new PdfDocument();
// crate a page description
PageInfo pageInfo = new PageInfo.Builder(595, 842, 1).create();
// start a page
Page page = document.startPage(pageInfo);
Canvas canvas=page.getCanvas());
// draw something on the page
Paint paint = new Paint();
paint.setColor(Color.RED);
canvas.drawCircle(50, 50, 30, paint);
// finish the page
document.finishPage(page);
// write the document content
document.writeTo(getOutputStream());
// close the document
document.close();
The page content is defined with Canvas object. Just another example. I hope this helps you.
The jspdf library is being used to generate PDF files in html.
That's a really good thing.
But I have a problem with pdf.
The data is about three pages long, but if check the downloaded pdf file, I see only one page and the rest will be truncated.
Here's my code:
let pdfName = this.contractlist_detail.title
var doc = new jsPDF();
var NotoSansCJKjp;
doc.addFileToVFS('NotoSansCJKjp-Regular.ttf', VFS);
doc.addFont('NotoSansCJKjp-Regular.ttf', 'NotoSansCJKjp', 'Bold');
doc.setFont('NotoSansCJKjp', 'Bold');
doc.setFontSize(12);
var paragraph = data;
var lines = doc.splitTextToSize(paragraph, 150);
doc.text(15, 15, lines)
doc.save(pdfName + '.pdf');
How do I make all of my data visible to downloaded pdf without being truncated?
jspdf library doesn't handle multi-pages by its own. You need to add pages manually when content is cropped (you need also to calculate manually if text is cropped).
Here is the method to add a new page :
addPage method
a demo is available in section "two page hello world" to know how to use this method

I am using grails 2.5.2.
I have created a table which shows all the data from database to gsp page and now i need to save that shown data in a pdf format with a button click.What will be the best way to show them into a PDF and save it to my directory. please Help
You can use itext for converting HTML into pdf using the code below:
public void createPdf(HttpServletResponse response, String args, String css, String pdfTitle) {
response.setContentType("application/force-download")
response.setHeader("Content-Disposition", "attachment;filename=${pdfTitle}.pdf")
Document document = new Document()
Rectangle one = new Rectangle(900, 600)
document.setPageSize(one)
PdfWriter writer = PdfWriter.getInstance(document, response.getOutputStream())
document.open()
ByteArrayInputStream bis = new ByteArrayInputStream(args.toString().getBytes())
ByteArrayInputStream cis = new ByteArrayInputStream(css.toString().getBytes())
XMLWorkerHelper.getInstance().parseXHtml(writer, document, bis, cis)
document.close()
}
Though answering this question late,take a look at grails export plugin.It will be useful if you want to export your data to excel and pdf( useful only if there is no in pre-defined template to export).
Got idea from itext. Used itext 2.1.7 and posted all the values to pdf from a controller method. Used images as background and paragraph and phrase to show values from database.
I'm creating a web app and using a php FPDF script to creates and print out a pdf. This also prints out on the pdf images that are uploaded to the app, which is no problem. However, it needs to do the same thing for an uploaded pdf and that is where my problem lies. How can I print a pdf as an image inside of a pdf using fpdf?
I have heard of imageMagick but I don't think that is an option because it is a software and I don't know where I would run it.
You can use FPDI to import a page of an existing PDF document and place it with FPDF onto a newly created page:
<?php
require_once('fpdf.php');
require_once('fpdi.php');
$pdf = new FPDI();
// load the document and get the total page count
$pageCount = $pdf->setSourceFile("the/document/you/want/to/import/a/page/from.pdf");
// import the first page
$tplIdx = $pdf->importPage(1);
// add a page
$pdf->AddPage();
// use the imported page on x=10, y=10 and a width of 90
$pdf->useTemplate($tplIdx, 10, 10, 90);
// output the PDF document
$pdf->Output();
I pieced together some code to insert a dynamic image into a PDF using both ColdFusion and iText, while filling in some form fields as well. After I got it working and blogged about it, I couldn't help but think that there might be a better way to accomplish this. I'm using the basic idea of this in a production app right now so any comments or suggestion would be most welcomed.
<cfscript>
// full path to PDF you want to add image to
readPDF = expandpath(”your.pdf”);
// full path to the PDF we will output. Using creatUUID() to create
// a unique file name so we can delete it afterwards
writePDF = expandpath(”#createUUID()#.pdf”);
// full path to the image you want to add
yourimage = expandpath(”dynamic_image.jpg”);
// JAVA STUFF!!!
// output buffer to write PDF
fileIO = createObject(”java”,”java.io.FileOutputStream”).init(writePDF);
// reader to read our PDF
reader = createObject(”java”,”com.lowagie.text.pdf.PdfReader”).init(readPDF);
// stamper so we can modify our existing PDF
stamper = createObject(”java”,”com.lowagie.text.pdf.PdfStamper”).init(reader, fileIO);
// get the content of our existing PDF
content = stamper.getOverContent(reader.getNumberOfPages());
// create an image object so we can add our dynamic image to our PDF
image = createobject(”java”, “com.lowagie.text.Image”);
// get the form fields
pdfForm = stamper.getAcroFields();
// setting a value to our form field
pdfForm.setField(”our_field”, “whatever you want to put here”);
// initalize our image
img = image.getInstance(yourimage);
// centering our image top center of our existing PDF with a little margin from the top
x = (reader.getPageSize(1).width() - img.scaledWidth()) - 50;
y = (reader.getPageSize(1).height() - img.scaledHeight()) / 2 ;
// now we assign the position to our image
img.setAbsolutePosition(javacast(”float”, y),javacast(”float”, x));
// add our image to the existing PDF
content.addImage(img);
// flattern our form so our values show
stamper.setFormFlattening(true);
// close the stamper and output our new PDF
stamper.close();
// close the reader
reader.close();

<!— write out new PDF to the browser —>
<cfcontent type=”application/pdf” file = “#writePDF#” deleteFile = “yes”>
<cfpdf> + DDX seems possible.

I have made it in another way with itext library
I don´t want overwrite my existing pdf with the image to insert, so just modify the original pdf inserting the image, just insert with itext doesn´t work for me.
So, I have to insert the image into a blank pdf (http://itextpdf.com/examples/iia.php?id=59)
And then join my original pdf and the new pdf-image. Obtaining one pdf with several pages.
(http://itextpdf.com/examples/iia.php?id=110)
After that you can overlay the pdf pages with this cool concept
