#35 barcode4j: trunk svn372, can't set params like height etc.

[Markus Rietzler]

i want to generate QRCodes for my pdfs unsing fop-servlet as tomcat webapp.

so far i am using

• barcode4j 2.0,
• fop 1.1.
• running a fop servlet in tomcat 8 with java-sun version 8 on my ubuntu server.

i can produce code39 codes. this is the code i am using at the moment to generate my code39 barcode:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                              xmlns:fo="http://www.w3.org/1999/XSL/Format";
                                xmlns:java="http://xml.apache.org/xslt/java"; exclude-result-prefixes="java"
                              xmlns:barcode="org.krysalis.barcode4j.xalan.BarcodeExt"
                              extension-element-prefixes="barcode">
<!-- ..... -->

<fo:block text-align="end">
  <fo:instream-foreign-object>
    <xsl:variable name="barcode-cfg">
    <barcode>
      <code39>
        <height>113.5mm</height>
        <!-- wide-factor>6.75</wide-factor -->
        <module-width>0.3mm</module-width>
        <interchar-gap-width>4mw</interchar-gap-width>
        <quite-zone enabled="true">30mw</quite-zone>
        <human-readable>
         <placement>none</placement>
        </human-readable>
      </code39>
    </barcode>
    </xsl:variable>
    <xsl:copy-of select="barcode:generate($barcode-cfg, /Order/ticket/id)" />
  </fo:instream-foreign-object>
</fo:block>
<!-- .... -->

i get a pdf with code39 barcode, works pretty well since many years.

i now want to generate qrcodes. i have installed barcode4j trunk (svn version 372). run ant and copied the barcode4j jars in my lib dir
together with zxing-core-1.7.jar

with the following code i can generate an qrcode and code39 barcode (with the default params)
i get a pdf with both barcodes

<fo:block text-align="end">
  <fo:instream-foreign-object>
    <barcode:barcode
          xmlns:barcode="http://barcode4j.krysalis.org/ns";
          message="123123" >
      <barcode:qr/>
    </barcode:barcode>
  </fo:instream-foreign-object>
  <fo:instream-foreign-object>
    <barcode:barcode
          xmlns:barcode="http://barcode4j.krysalis.org/ns";
          message="123123" >
      <barcode:code39>
        </barcode:code39>
    </barcode:barcode>
 <!--  </xsl:variable>
    <xsl:copy-of select="barcode:generate($barcode-cfg, /Order/ticket/id)" />
-->
  </fo:instream-foreign-object>
</fo:block>

BUT i can not define any options like height, width etc.

when i try to use

<barcode:barcode
      xmlns:barcode="http://barcode4j.krysalis.org/ns";
      message="123123" >
  <barcode:code39>
     <height>45mm</height>
  </barcode:code39>
</barcode:barcode>

i get a blank page, even with <barcode:height>. no pdf is generated! </barcode:height>

what is missing? why can't i set any options to generate the barcode?

as a work-a-round i am using fo:external-graphic with a http-call to get a qrcode image to insert in my pdf. but i want to go the way without external-praphic and use barcode4j

Thank you
