Hi,

I'm working on an application which creates mailmerge documents with Aspose.Word.
In these documents a barcode font is used to show a reference number.
This works just fine.
When I try to convert the documents to PDF by using Aspose.PDF the reference number is shown with a normal font instead of the barcode font.
Is this by design or am I doing something wrong?

Greetings,
Erik-Jan Wardenier

Dear Wert,

Thank you for considering Aspose.

Can you please provide an example and let me test it?

Dear Forever,
We are using the 'Code 39 truetype font package' found at: http://www.barcodesinc.com/free-barcode-font/

In this example I created the barcoded part like this:

                bldr = New DocumentBuilder(doc)
                bldr.MoveToBookmark("bmRefNo")
                bldr.Font.Name = "Free 3 of 9 Extended"
                bldr.Font.Size = 28
                bldr.Write("*" & sRefNo & "*")
 
Kind regards,

Erik-Jan Wardenier

I have reproduced this error. I will check the reason and reply to you soon.

I have found that font embeding is needed to display the barcode. It is not supported to set font embeding in Aspose.Word so you have to add IsFontEmbedded="true" into the xml by yourself. You can test the following example:
<?xml version="1.0" encoding="UTF-8"?>
<Pdf xml:space="preserve" TabStopPosition="36"  IsFontEmbedded="true" IsCoreFontUsed="false" IsPageNumberForDocument="true" xmlns="Aspose.Pdf">
  <Section PageWidth="612" PageHeight="792" PageMarginTop="72" PageMarginBottom="72" PageMarginLeft="90" PageMarginRight="90" IsNewPage="true">
    <Text IsSpaced="true" LineSpacing="2.94" ID="bmRefNo">
      <Segment FontName="Free 3 of 9 Extended" Color="rgb 0 0 0" FontSize="28">*123456*</Segment>
    </Text>
  </Section>
</Pdf>

Thanks,

This does the trick, although I consider it more or less as a work around.

Kind regards,

Dear Forever,

We have been using your solutions for some weeks now.
The following problem arises: the documents are getting very big (450kb instead of 45kb).
This is caused by embedding the font.
We generate around 20 documents on each run.
Is there a way to decrease the size of the pdfs?

Kind regards,
Erik-Jan Wardenier

Dear Erik-Jan,

Thank you for considering Aspose.

I will keep this issue in my mind and try to find a solution.

I have tested this issue and found if you use the following xml:
    <Text IsSpaced="true" LineSpacing="2.94">
      <Segment FontName="Free 3 of 9 Extended Regular" Color="rgb 0 0 0" FontSize="28" IsUnicode="true">*123456*</Segment>
    </Text>
the resulting pdf will be smaller. Note that you should set IsUnicode to true and the fontname should be Free 3 of 9 Extended Regular.

I followed these steps and added the IsUnicode="true" to the following XML using XPath and XmlDocument.


<?xml version="1.0" encoding="UTF-8"?><Pdf xml:space="preserve" TabStopPosition="36" IsCoreFontUsed="false" IsPageNumberForDocument="true" xmlns="Aspose.Pdf">
  <Section PageWidth="595.3" PageHeight="841.9" PageMarginTop="27" PageMarginBottom="9" PageMarginLeft="45.1" PageMarginRight="46.2" IsNewPage="true">
    <Table ColumnWidths="261 18 45 153 45" MarginLeft="-9" DefaultCellPaddingLeft="5.4" DefaultCellPaddingRight="5.4" IsRowBroken="false" IsFirstRowRepeated="false">
      <Row>
        <Cell>
          <Text IsSpaced="true" LineSpacing="5.4" ID="DOCUMENTIDBARCODE">
            <Segment FontName="Free 3 of 9 Extended" FontSize="36" IsUnicode="true">*</Segment>
            <Segment FontName="Free 3 of 9 Extended" FontSize="36" IsUnicode="true">7002498</Segment>
            <Segment FontName="Free 3 of 9 Extended" FontSize="36" IsUnicode="true">*</Segment>
          </Text>
        </Cell>
      </Row>
    </Table>
  </Section>
</Pdf>

But the barcode doesn't dispaly in the PDF. If I save the word document out before converting to PDF...the barcode is in there fine.

Have you got any other suggestions?

BTW here's how I added the attribute.

                XmlNamespaceManager nsmgr = new XmlNamespaceManager(xmlDoc.NameTable);
                nsmgr.AddNamespace("apdf", "Aspose.Pdf");

                //hackery to get font included in PDF find
                //<Segment FontName="Free 3 of 9" FontSize="36">
                //and replace with
                //<Segment FontName="Free 3 of 9" FontSize="36" IsUnicode="true">
                foreach (XmlElement barcodeFontSegmentNode in xmlDoc.SelectNodes("//apdf:Segment[@FontName='Free 3 of 9']", nsmgr))
                {
                    barcodeFontSegmentNode.SetAttribute("IsUnicode", "true");
                    barcodeFontSegmentNode.SetAttribute("FontName", "Free 3 of 9 Extended");
                }


Thanks

Dear Jeremy,

Using this solution, you have to set the font name as "Free 3 of 9 Extended Regular" as you can see from the system's fonts folder.

I did try that and that didn't work.

I will download the font again and remove it and add it again and try again.

Any other suggestions of what else it could be?

How can I confirm the font name in Windows/Fonts folder...is it the filename without the .ttf?

Thanks
Jeremy

Dear Jeremy,

You can double click the font file to see the font name. For this font, the name at the top is "Free 3 of 9 Extended Regular" and the font name at the second line is "Free 3 of 9 Extended".  Both these names should be correct font name. I have attached the new dll that support both two font names. If you are using fontmap like the following:

   pdf.IsTruetypeFontMapCached = true;
   pdf.TruetypeFontMapPath = @"d:\test";

Please delete the Aspose.Pdf.TruetypeFontMap.xml in the TruetypeFontMapPath and let it regenerated.

I have got it working so that when viewing the PDF it shows the barcode correctly. Based on using:

                XmlNamespaceManager nsmgr = new XmlNamespaceManager(xmlDoc.NameTable);
                nsmgr.AddNamespace("apdf", "Aspose.Pdf");

                foreach (XmlElement barcodeFontSegmentNode in xmlDoc.SelectNodes("//apdf:Segment[@FontName='Free 3 of 9 Extended Regular']", nsmgr))
                {
                    barcodeFontSegmentNode.SetAttribute("IsUnicode", "true");
 barcodeFontSegmentNode.SetAttribute("TruetypeFontFileName", @"C:\WINDOWS\Fonts\FRE3OF9X.TTF");
                }

But now when I actually try and print the PDF to a printer the printer warms up and nothing comes out. If I go to advanced button and tick the check box "Print as image" it actually works.

Is there a setting I can set in the PDF that will automatically set this setting?

Thanks very much,
Jeremy

Dear Jeremy,

Do you mean setting the "Print as image"? I don't think it can be set in Pdf document.

I tried printing with mormal mode and it works well. Can you please provide a example xml that can reproduce this error?
