Converting Postscript to PDF Documents

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 AEM Forms.

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 AEM Forms 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 AEM forms 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.
