PDFjet for Java is available under both free evaluation and paid for licenses.
PDFjetB4A can be used with both the free evaluation and paid for licenses.
The free license version used to be feature limited, it looks as though the latest free license version contains all the features of the paid for license but i have not checked that.
PDFjetB4A wraps all available features of the paid for license version - if any of those features are not available in the free license version then the features will show in the B4A IDE but not be available for use.
Trying to use a feature that is not available is like to raise a ClassNotFound exception.

~~In order to use PDFjetB4A you will need to:~~

~~Download the free evaluation PDFjet for Java from: http://pdfjet.com/java/download.html~~
OR
~~Purchase and download the paid for PDFjet for Java from: http://pdfjet.com/java/buy.html~~

~~When downloading either version you will agree to and accept the license terms and conditions that apply to the version you download.~~

EDIT: Please read post #2 to find out about all available versions of PDFjet for Java.

Your PDFjet for Java download will contain the java library file PDFjet.jar.
Copy PDFjet.jar to your B4A additional libraries folder.

Now download the attached PDFjetB4A library files and copy these to your B4A additional library folder.
Your B4A additional libraries folder should now contain: PDFjetB4A.jar, PDFjetB4A.xml and PDFjet.jar.
PDFjetB4A.html is for reference only - you don't need to copy this file to your additional libraries folder.
If you upgrade from the free version to the paid for version you just need to overwrite the free version of PDFjet.jar with your paid for version of PDFjet.jar.

One thing i have not done is to add a lot of the javadoc reference to the B4A library.
Many methods are self-explanatory, some are obscure and some lack any javadoc reference.
In your download from pdfjet.com there is a folder docs/java which contains the PDFjet for Java javadoc reference.
Open docs/java/index.html in your browser to see all the available reference/documentation.

I have also created a B4J version of this library, see the jPDFjet thread.
Both B4A and B4J versions share the same syntax.

There are some java examples of usage of PDFjet both online and in the download from pdfjet.com.
I have converted some of these java examples to a B4J project and this B4J project is available in the jPDFjet thread.
(I've not had time to create a B4A demo project).

Library files attached.

Martin.

Any example to create table to make a report?
I'm using the other pdf library and I'm tired with the tables.

warwound · Sep 23, 2015

Have you tried the PDFjet B4J demo yet?
https://www.b4x.com/android/forum/threads/jpdfjet.37842/
It contains a table example - you will i think find that a table is the best option for reports.

AddPage - ?? Anyone get this feature to work?

Is there ANY way to make a second page?

It looks as though PDFjetTextColumn is only available with the full (paid for) version of PDFjet.
You're using the free open source version are you?

When I look at the Open Java Source

B4X:

  /**
  *  Creates page object and add it to the PDF document.
  *
  *  Please note:
  *  <pre>
  *  The coordinate (0f, 0f) is the top left corner of the page.
  *  The size of the pages are represented in points.
  *  1 point is 1/72 inches.
  *  </pre>
  *
  *  @param pdf the pdf object.
  *  @param pageSize the page size of this page.
  */
  public Page(PDF pdf, float[] pageSize) throws Exception {
  this(pdf, pageSize, true);
  }


  /**
  *  Creates page object and add it to the PDF document.
  *
  *  Please note:
  *  <pre>
  *  The coordinate (0f, 0f) is the top left corner of the page.
  *  The size of the pages are represented in points.
  *  1 point is 1/72 inches.
  *  </pre>
  *
  *  @param pdf the pdf object.
  *  @param pageSize the page size of this page.
  *  @param addPageToPDF boolean flag.
  */
  public Page(PDF pdf, float[] pageSize, boolean addPageToPDF) throws Exception {
  this.pdf = pdf;
  contents = new ArrayList<Integer>();
  annots = new ArrayList<Annotation>();
  destinations = new ArrayList<Destination>();
  width = pageSize[0];
  height = pageSize[1];
  buf = new ByteArrayOutputStream(8192);

  if (addPageToPDF) {
  pdf.addPage(this);
  }
  }

There are TWO page Init routines. The Second one takes a Boolean to indicate AddPageToPDF. To me this implies that we can have more than one page.

Is there anyway I can call the second init routine. The XML file has only the first init routine.

BobVal

PS: I just walked thru all the Java open source and to me it appears that AddPage and more than one page should work. But it doesn't. The two routines that do all this are PDF.java and Page.java

Version 5.68

If I try and compile version 5.68 and use it I crash ( PDFJet has stopped working )
if I download the Evaluation version of 5.68 and try it I crash ( PDFJet has stopped working )

Does the 5.68 no longer work with B4A

Hello
How do I change print orientation from left to right ?
I want the font type allowed to write Arabic and English.

Baris Karadeniz · May 11, 2016

Can I use this library for viewing existing pdf file which is downloaded with webview? There will not be any change on the pdf file.

I think is is only for CREATING PDFs with b4a as stated in Post #1. I don´t think that it can show a PDF but i´m not sure; never used this lib.

Hello Warwound,
I am evaluating this library and I am trying to print these characters: Š Đ Č Ć Ž, but I get only first and last letter.
I am attaching generated PDF file, look at the second line.
Can you point me in the right direction what to do (I am a newbie)?

Thanks.
