#37 ean-128, Bar code is correct, code display format issues

Samael — Fri, 09 Aug 2024 14:05:44 -0000

I've done some testing of this on my fork: https://github.com/singingBush/barcode4j

The EAN128LogicImpl.java will add brackets itself by default unless you use <barcode:omit-brackets>true</barcode:omit-brackets> so perhaps what's needed here is:

<fo:instream-foreign-object>
    <barcode:barcode
        xmlns:barcode="http://barcode4j.krysalis.org/ns"
        message="{$message}" orientation="0">
        <barcode:ean-128>
            <barcode:height>18mm</barcode:height>
            <barcode:module-width>0.43mm</barcode:module-width>
            <barcode:human-readable>
                <barcode:pattern font-size="20pt">(__) _______ __________ ___</barcode:pattern>
                <barcode:omit-brackets>true</barcode:omit-brackets>
            </barcode:human-readable>
        </barcode:ean-128>
    </barcode:barcode>
</fo:instream-foreign-object>

I tested locally and I was able to get an expected result

ean-128, Bar code is correct, code display format issues

Chandrashekar S — Mon, 26 Sep 2022 06:33:18 -0000

I am generating ean-128 code for a Project, below is the code. Attached is the image.
the bar code is getting generated correctly, however the code displayed is having multiple brackets, I used different combinations of pattern and template but didn't help.

can you please help? let us know if we can have a call to walk through the issue.

Markus Rietzler — Fri, 03 May 2019 13:34:27 -0000

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

Markus

Bad symbols while generating EAN13 barcode

Andris — Wed, 21 Nov 2018 09:53:43 -0000

Hi guys,

I have issue with barcode generation. It happens only on test server, on my local machine everythink works as expected. On test server when I generate barcode, I have got bad symbols instead of numbers. Code is absolutely the same in both environments. Any suggetions why this may happens?

Thanks,
Andris

Code39 doesn't scan on Paper but on PDF

SANDEEP SANGOLE — Thu, 16 Feb 2017 15:05:16 -0000

Hi All, I am using Apache FOP and barcode4j to generate barcode.The number of letters in my barcode is 18 and page width is 5.5cm. When I reduce the width barcode fits into the page and barcode is still scannable from pdf.But when its printed on paper its not printing propertly, lines are to dark and doesnt look clear. Could you please help me if there is any workaround ?
Find below XSL template,

CODE128A width setting problem

Mayur Maheshwari — Mon, 08 Sep 2014 13:21:16 -0000

Hi,

I am using barcode4j to generate barcodes by using CODE128A. I am unable to set barcode width as per the label printer label having size 35mm x 15mm. The message which i am passing to the 'Code128Bean' is a alphanumeric like 'RET1812345678Z'.

Please help me.

Thanks.
