Pdfa Parameters

When using the "Pdfa" web service, both the

 

•"<convert>" and

•"<analyze>"

 

operations can be used. The "convert" operation is used to convert PDF documents to PDF/A, while the "analyze" operation is used to validate existing PDF/A documents.

 

 

convert operation

 

Used to convert a PDF document to PDF/A.

       }
     }
   }
 }
}

 

 

convert element

 

Used to define the parameters for the PDF/A conversion.

 

<convert errorReport="message" level="3u" imageQuality="75" successReport="linked" autoTagging="false">
...
</convert>
 

"convert": {
  "errorReport": "message",
  "level": "3u",
  "imageQuality": "75",
  "successReport": "linked",

  "autoTagging": false,
     ...
}

 

level (default: "1b")

Specifies the compliance level when creating PDF/A documents (as specified in ISO 19005).

1a = PDF/A-1a

1b = PDF/A-1b

2a = PDF/A-2a

2b = PDF/A-2b

2u = PDF/A-2u

3a = PDF/A-3a

3b = PDF/A-3b

3u = PDF/A-3u

 

imageQuality (default: 75)

The quality for images which must be transformed during the conversion because they use a compression which is not allowed (e.g. JPX is not allowed in PDF/A-1) is defined using this parameter. Values in a range from 1 to 100 are allowed whereby a higher value means better quality, but also larger PDF documents.

 

errorReport (default: "none")

This parameter is used to define whether and in which format the XML report for a failed conversion will be returned.

 none = An XML report will not be returned

message = The XML report will be returned as part of the error message

file = The XML report will be saved in a file

 

successReport (default: "none")

 This parameter is used to define whether and in which format the XML report for a successful conversion will be returned.

 none = An XML report will not be returned

 linked = The XML report will be appended at the end of the PDF/A document.

 zip = The PDF/A document and the XML report will be packaged together in a ZIP archive.

 

tipp

The format of the document generated with "errorReport" and "successReport" is described by the http://schema.webpdf.de/1.0/report/pdfa.xsd schema.

 

autoTagging (Default: false)

In order to convert a document to conformity levels PDF/A 1a-3a, the entire document must have appropriate structure information (tags). If auto tagging is enabled, the corresponding structure information (in the form of page tags) will be generated automatically before the actual conversion.

 

zugferd element

 

This element can be optionally used to integrate a ZUGFeRD document. The document must at least be converted to PDF/A-3 format.

 

<zugferd>
  <xmlFile version="V10_COMFORT">
      PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiPz4NCg0KPHBy
      ...
      dD4=
  </xmlFile>
</zugferd>

"zugferd": {
  "xmlFile": {

       "version": "V10_COMFORT",
      "value": "PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiPz4NCg0KPHBy...dD4="
  }
}
 

 

xmlFile element

 ZUGFeRD file (XML) in "Base64 encoded" format. The ZUGFeRD XSD schema will be used to validate the file before embedding. If it is not valid, the operation will be aborted.

 

version (Default: v10Comfort)

Used to define the version of the ZUGFeRD XML file that should be embedded with "xmlFile". Versions 1.0 and 2.0 are supported. Only the “Comfort” profile is available for version 1.0. Meanwhile, the "Minimum", "Basic WL", "Basic", "EN16931" (Comfort), and "Extended" profiles are supported for version 2.0.

 

List of versions with the corresponding profiles:

v10Comfort

v20Minimum

v20BasicWL

v20Basic

v20EN16931

v20Extended

 

 

analyze operation

 

Used to check a PDF document for compliance with PDF/A specifications.

 

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<operation xmlns="http://schema.webpdf.de/1.0/operation">
<pdfa>
  <analyze level="1b"/>
</pdfa>
</operation>

 

{
"pdfa": {
  "analyze": {
    "level": "1b"
   }
 }
}

 

 

analyze element

 

Used to define the parameters for the PDF/A check.

 

<analyze level="1b"/>
 

 

"analyze": {
"level": "1b"
}

 

level (default: "1b")

PDF/A level that will be used for the compliance check (please refer to the convert operation)
