How to generate PDF using fonts from Extended Font Pack?

Hello
Extended Font Pack, available for download contains MyriadPro-Regular.otf font that has cyrillic glyphs.
I want to generate PDF document with cyrillic unicode data that can refer to the MyriadPro-Regular font resource without embedding font.
Are Extended Font Pack resources CID keyed fonts or not?
Looks like such example of PDF structure allowed me to use it only in ANSI encoding
           'Type':'/Font',
            'Subtype':'/Type1',
             'Name': '/MyriadPro-Regular' ,
            'BaseFont': '/MyriadPro-Regular',
             'Encoding': '/WinAnsiEncoding',
What values should be for `Subtype` and `Encoding` to render cyrillic unicode (UTF-8 encoded) data and use MyriadPro-Regular Open Type downloaded from adobe and installed into local system without embedding it?
Thanks

Sorry for the delay. I admired with investigation of this case.
My aim is to generate PDF docs on web site that have i18ned content. ALso client does not want to deal with any font licenses (font embedding will raise question about font licensing) and to reduce PDF file size with such approach. So I'm looking for the ability to link fonts in PDF source, that can be easiely downloaded from adobe.com and installed into local desktop. With Latin group (en-us, french, german) we can use one of the 14 standard fonts, for CJK - Adobe Asian Font pack. I was considering (Myriad Pro or Minion Pro) font resources from Extended Font pack to cover Cyrillic glyphs. I observed that such fonts are usually installed with Adobe Reader installation (MyriadPro-regular.otf). To render cyrillic glyphs I followed such steps like converted into cp1251 encoding range of the cyrillic unicode data (as you told those fonts do not support unicode encodings the same way as CID keyed asian fonts) and pointed to the Type1 MyriadPro-Regular with custom WinAnsiEncoding. One problem I faced with is - that glyphnames are differrent in diferent Extended Font pack versions. I mean that cyrillic glyphnames for the Adobe Reader 8 started from `afii100xx`, when for the Adobe Reader 9 they are named `uni0xx` for the same font named MyriadPro. I used such glyphnames in the /Differences list in PDF source. How can I generate PDF source that can be viewed successfully in both Adobe Readers version 8 and 9?

How to generate PDF using FDF file and the PDF form template (PHP)

Hi Folks,
I'm really sorry that I couldn't follow all the valuable discussions going on here, regularly. I need some immediate help.
I NEED A PHP SOLUTION. I'm able to generate FDF files using the PDF Form Template in PHP. So, I have a collection of FDF files, which seeks the PDF template, while opened and populates the template with FDF data. Now if I need to save this PDF file, I have to do it manually clicking SAVE option. But, I need to convert FDF to PDF in bulk. So, I need some PHP based solution. The PHP script takes the PDF template and the FDF file and merges them to generate a complete populated PDF file. I know it's possible, but don't know how. I've seen Adobe FDF Toolkit. But by default it doesn't show any guideline for PHP. Please help me to write this code. I'm a professional coder. I can understand your hints and tutorials. PLEASE HELP GOOD PEOPLE.

The only reason I am responding to this post is because the poster sent me a request through the forum message system asking for my help.
Although I did populate PDFs with FDF data generated by web forms a year or so ago, I have since abandoned that kind of solution. It was a big headache. I found it far more stable and flexible to use html, php and css to populate forms that are almost as nice looking as PDFs.
So my advice is, if you can possibly avoid going the FDF/PDF route, you will be better off.

How to generate PDF report directly instead of RPT report by using JRC ?

Hi,
Good Day !
How to generate PDF report directly instead of RPT report by using Crystal Reports XI Release 2 Java Reporting Component (JRC) in desktop (Swing thick-client) ?
My GUI program will generate a RPT report, then i can export to PDF file, this is ok, no problem.
BUT
i want it direct to generate a PDF report, not a RPT report.
The code like below (2 java files)
ClassA.java
ReportClientDocument reportClientDoc = new ReportClientDocument();
reportClientDoc.open(XXX, 0);
ParameterFieldController paramFieldController = reportClientDoc.getDataDefController().getParameterFieldController();
paramFieldController.setCurrentValue("", "XXX", DomainClass.getXXX());
new ReportViewerFrame(reportClientDoc);
// End of ClassA.java
// Begin ReportViewerFrame.java
public class ReportViewerFrame extends JFrame
       //Initial window frame properties.
     private final int XPOS = 80;
     private final int YPOS = 60;
     private final int WIDTH = 760;
     private final int HEIGHT = 550;
     private ReportViewerBean reportViewer = new ReportViewerBean();
     private ReportClientDocument reportClientDoc = new ReportClientDocument();
     public ReportViewerFrame(ReportClientDocument reportClientDoc) throws    Exception
          //Initialize frame properties.
          this.setResizable(true);
          this.setLocation(XPOS, YPOS);
          this.setSize(WIDTH, HEIGHT);
          this.setTitle("Crystal Report Java Viewer");
          //Add GUI components to the frame including the ReportViewerBean.
          addComponents();
          //Add GUI listeners to the frame.
          addListeners();
          //Set the report that the ReportViewerBean will display.
          this.reportClientDoc = reportClientDoc;
          reportViewer.setReportSource(reportClientDoc.getReportSource());
          reportViewer.init();
          reportViewer.start();
          //Display the frame.
          this.setVisible(true);
How to set the export option to PDF base on existing code ?
Where can i download this package/jar ?
regards

Please find a console app that you can extend it to a JFrame app by importing the relevant swing package:

     public static void main(String[] args) {
          try {
               //Open report.
               ReportClientDocument reportClientDoc = new ReportClientDocument();
               reportClientDoc.open(REPORT_NAME, 0);
               //NOTE: If parameters or database login credentials are required, they need to be set before.
               //calling the export() method of the PrintOutputController.
               //Export report and obtain an input stream that can be written to disk.
               //See the Java Reporting Component Developer's Guide for more information on the supported export format enumerations
               //possible with the JRC.
               ByteArrayInputStream byteArrayInputStream = (ByteArrayInputStream)reportClientDoc.getPrintOutputController().export(ReportExportFormat.PDF);
               //Release report.
               reportClientDoc.close();
               //Use the Java I/O libraries to write the exported content to the file system.
               byte byteArray[] = new byte[byteArrayInputStream.available()];
               //Create a new file that will contain the exported result.
               File file = new File(EXPORT_FILE);
               FileOutputStream fileOutputStream = new FileOutputStream(file);
               ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(byteArrayInputStream.available());
               int x = byteArrayInputStream.read(byteArray, 0, byteArrayInputStream.available());
               byteArrayOutputStream.write(byteArray, 0, x);
               byteArrayOutputStream.writeTo(fileOutputStream);

Problem while generating PDF using iText

Hi:
I have generated PDF using iText, where i have written all code in sequential flow.
<code>
com.lowagie.text.Document document = new com.lowagie.text.Document(PageSize.A4, 55, 5, 20, 20);
OutputStream outputstream = response.getOutputStream();
PdfWriter.getInstance(document,outputstream);
</code>
And i have added all fields in the document.
But my problem is how to display total pagecount on all pages e.g.1\20 (because i have generated PDF sequentially)
Also i want to add watermark on all pages.
So, can any body help me to solve this problem?
Thank You,
Balaji

To generate PDF using BI APIs and loadjava utility

Hi All,
I am trying to generate PDF using BI APIs(FOProcessor etc).
I have generated XML data through the PL/SQl procedure and storing it in a file. This file is loacted in database tier.
The APIs is used through a simple java program which is application tier. To test the process, I had to manually provide the XML file to the java class in order to generate PDF and it does generate.
Now the issue is I need to load the java class to the database so that everything gets automated(loadjava utlility).
when i try to do it, it give no class found error.
Do I need to load the referenced classes in the java file , that is, FOProcessor,RTFProcessor,FOUtility,jdbc.driver.OracleDriver as well?
If the above is not possible, is it possible to reference a file in database tier from application tier so that i can use the XML file as input the java class in application tier.
thanks,
Srik

How to generate and use Matlab(R2007) .dll's in Labview

Is there a step-by-step example on how to generate and use Matlab(R2007) .dll's in Labview.
Our experimenal hardware is LabView-controlled and we want to pass
images/2d intensity arrays to a more complex matlab program that will
return an array of extracted data which we want to use in LabView again.
Thank you
Carsten

I recommend having a wrapper created around the matlab dll that converts the datatypes for you. There is a lot of fooling around with pointers involved which is very difficult in LabVIEW. btw, this got much more complicated after Matlab 7. Essentially, you need to convert your inputs into mxArrays, and then add those mxArrays to an mxArray list that you pass by pointer into the matlab dll. You also need to create a mxArray list for the outputs from the dll which you will need to extract your data out of before converting it back into a LabVIEW supported datatype. It's a big hassle. We do this pretty often, but we have created a c library that handles all the conversions, so it is feasible for us. Unfortunately, I can't share the library, but hopefully this information will help you get where you want to be.
Like I said, it would be easier if you can just get a c developer to write a wrapper for you to keep it simple in LabVIEW. Alternatively, you might try getting your m-code to work in Mathscript.

Hi,
You can refer the page items in your page header as &itemname. For example, if I have page item P15_TEST, I will add the following in header:
<marquee>
&P15_TEST.
</marquee>But make sure that you have a process before header to populate the value in your page item. Otherwise, there will be a null scrolling (which you can't see!) :)
