About the Distiller ServiceThe Distiller® service converts PostScript®,
Encapsulated PostScript (EPS), and PRN files to compact, reliable,
and more secure PDF files over a network. The Distiller service
is frequently used to convert large volumes of print documents to
electronic documents, such as invoices and statements. Converting documents
to PDF also allows enterprises to send their customers a paper version
and an electronic version of a document.
Converting PostScript to PDF documentsThis topic describes how you can use the
Distiller Service API (Java and web service) to programmatically
convert PostScript (PS), Encapsulated PostScript (EPS), and PRN
files to PDF documents.
Note: To convert PostScript files to PDF documents,
one of the following needs to be installed on the server hosting
LiveCycle: Acrobat 9 or Microsoft Visual C++ 2005 redistributable
package.
Summary of stepsTo convert any of the supported types to a PDF document,
perform the following steps:
Include project files.
Create a Distiller service client.
Retrieve the file to convert.
Invoke the PDF creation operation.
Save the PDF document.
Include project filesInclude the necessary files in your development
project. If you are creating a client application by using Java,
include the necessary JAR files. If you are using web services,
make sure you include the proxy files.
Create a Distiller service clientBefore you can programmatically
perform a Distiller service operation, you must create a Distiller
service client. If you are using the Java API, create a DistillerServiceClient object.
If you are using the web service API, create a DistillerServiceService object.
Retrieve the file to convertYou must retrieve the file that you
want to convert. For example, to convert a PS file to a PDF document,
you must retrieve the PS file.
Invoke the PDF creation operationAfter you create the service
client, you can then invoke the PDF creation operation. This operation
will need information about the document to be converted, including
the path to the target document.
Save the PDF documentYou can save the PDF document as a PDF
file.
Convert a PostScript file to PDF using the Java APIConvert a PostScript file to PDF document by using the
Distiller Service API (Java):
Include project files.
Include client JAR files,
such as adobe-distiller-client.jar, in your Java project’s class
path.
Create a Distiller service client.
Retrieve the file to convert.
Create a java.io.FileInputStream object
that represents the file to convert by using its constructor and
passing a string value that specifies the location of the file.
Create a com.adobe.idp.Document object by
using its constructor and passing the java.io.FileInputStream object.
Invoke the PDF creation operation.
Invoke the DistillerServiceClient object’s createPDF method
and pass the following values:
The com.adobe.idp.Document object
that represents the PS, EPS, or PRN file to be converted
A java.lang.String object that contains
the name of the file to be converted
A java.lang.String object that contains
the name of the Adobe PDF settings to be used
A java.lang.String object that contains
the name of the security settings to be used
An optional com.adobe.idp.Document object
that contains settings to be applied while generating the PDF document
An optional com.adobe.idp.Document object
that contains metadata information to be applied to the PDF document
The createPDF method
returns a CreatePDFResult object that contains the
new PDF document and a log file that may be generated. The log file typically
contains error or warning messages that are generated by the conversion
request.
Save the PDF document.
To obtain the newly created
PDF document, perform the following actions:
Similarly, to obtain the
log document, perform the following actions.
Converting a PostScript file to PDF using the web service APIConvert a PostScript file to PDF document by using the
Distiller Service API (web service):
Include project files.
Create a Microsoft .NET
project that uses MTOM. Ensure that you use the following WSDL definition: http://localhost:8080/soap/services/DistillerService?WSDL&lc_version=9.0.1.
Note: Replace localhost with the IP
address of the server hosting LiveCycle.
Create a Distiller service client.
Create
a DistillerServiceClient object by using its default constructor.
Create a DistillerServiceClient.Endpoint.Address object
by using the System.ServiceModel.EndpointAddress constructor. Pass
a string value that specifies the WSDL to the LiveCycle service
(for example, http://localhost:8080/soap/services/DistillerService?blob=mtom.)
You do not need to use the lc_version attribute.
This attribute is used when you create a service reference. However,
specify ?blob=mtom to use MTOM.
Create a System.ServiceModel.BasicHttpBinding object
by getting the value of the DistillerServiceClient.Endpoint.Binding field.
Cast the return value to BasicHttpBinding.
Set the System.ServiceModel.BasicHttpBinding object’s MessageEncoding field
to WSMessageEncoding.Mtom. This value ensures that
MTOM is used.
Enable basic HTTP authentication by performing the following
tasks:
Assign the LiveCycle user name to the
field DistillerServiceClient.ClientCredentials.UserName.UserName.
Assign the corresponding password value to the field DistillerServiceClient.ClientCredentials.UserName.Password.
Assign the constant value HttpClientCredentialType.Basic to the
field BasicHttpBindingSecurity.Transport.ClientCredentialType.
Assign the constant value BasicHttpSecurityMode.TransportCredentialOnly to
the field BasicHttpBindingSecurity.Security.Mode.
Retrieve the file to convert.
Create a BLOB object
by using its constructor. This BLOB object is used
to store the file to convert to a PDF document.
Create a System.IO.FileStream object by
invoking its constructor and passing a string value that represents
the file location and the mode to open the file in.
Create a byte array that stores the content of the System.IO.FileStream object.
You can determine the size of the byte array by getting the System.IO.FileStream object’s Length property.
Populate the byte array with stream data by invoking the System.IO.FileStream object’s Read method
and passing the byte array, the starting position, and the stream
length to read.
Populate the BLOB object by assigning its MTOM property
with the contents of the byte array.
Invoke the PDF creation operation.
Invoke the DistillerServiceService object’s CreatePDF2 method and
pass the following required values:
The BLOB object
that represents the PS file to convert
A string that contains the path name of the file to be convert
A string object that contains the Adobe PDF settings to be
used (for example, Standard)
A string object that contains the security settings to be
used (for example, No Security)
An optional BLOB object that contains settings
to be applied while generating the PDF document
An optional BLOB object that contains metadata
information to be applied to the PDF document
A BLOB output parameter used to store the
PDF document
A BLOB output parameter used to store the
log
Save the PDF document.
Create a System.IO.FileStream object
by invoking its constructor. Pass a string value that represents
the file location of the signed PDF document and the mode in which
to open the file.
Create a byte array that stores the content of the BLOB object
that was returned by the CreatePDF2 method (the
output parameter). Populate the byte array by getting the value
of the BLOB object’s MTOM data
member.
Create a System.IO.BinaryWriter object by
invoking its constructor and passing the System.IO.FileStream object.
Write the contents of the byte array to a PDF file by invoking
the System.IO.BinaryWriter object’s Write method
and passing the byte array.
