Converting PDF to Postscript and Image Files

Include project files.

Include client JAR files, such as adobe-convertpdf-client.jar, in your Java project’s class path.

Create a Convert PDF client.

• Create a ServiceClientFactory object that contains connection properties.
• Create a ConvertPdfServiceClient object by using its constructor and passing the ServiceClientFactory object.

Reference the PDF document to convert to a PostScript file.

• Create a java.io.FileInputStream object by using its constructor and pass a string value that specifies the location of the PDF document to convert.
• Create a com.adobe.idp.Document object that stores the PDF document by using the com.adobe.idp.Document constructor. Pass the java.io.FileInputStream object that contains the PDF document.

Set conversion run-time options.

• Create a ToPSOptionsSpec object by invoking its constructor.
• Set run-time options by invoking an appropriate method that belongs to the ToPSOptionsSpec object. For example, to define the PostScript level that is created, invoke the ToPSOptionsSpec object’s setPsLevel method and pass a PSLevel enumeration value that specifies the PostScript level. For information about all run-time values that you can set, see the ToPSOptionsSpec class reference in AEM Forms API Reference.

Convert the PDF document to a PostScript file.

Invoke the ConvertPdfServiceClientobject’s toPS2 method and pass the following values:

• A com.adobe.idp.Document object that represents the PDF document to convert to a PostScript file.
• A ToPSOptionsSpec object that specifies PostScript run-time options.

The toPS2 method returns a Document object that contains the new PostScript document.

Save the PostScript file.

• Create a java.io.File object and ensure that the file name extension is .ps.
• Invoke the Document object’s copyToFile method to copy the contents of the Document object to the file (ensure that you use the Document object that was returned by the toPS2 method).

Include project files.

Create a Microsoft .NET project that uses MTOM. Ensure that you use the following WSDL definition: http://localhost:8080/soap/services/ConvertPDFService?WSDL&lc_version=9.0.1.

NOTE

Replace localhost with the IP address of the server hosting AEM Forms.

Create a Convert PDF client.

• Create a ConvertPdfServiceClient object by using its default constructor.

• Create a ConvertPdfServiceClient.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/ConvertPDFService?blob=mtom.) You do not need to use the lc_version attribute. However, specify ?blob=mtom.

• Create a System.ServiceModel.BasicHttpBinding object by getting the value of the ConvertPdfServiceClient.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 ConvertPdfServiceClient.ClientCredentials.UserName.UserName.
  • Assign the corresponding password value to the field ConvertPdfServiceClient.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.

Reference the PDF document to convert to a PostScript file.

• Create a BLOB object by using its constructor. The BLOB object is used to store a PDF document that is converted to a PostScript file.
• Create a System.IO.FileStream object by invoking its constructor and passing a string value that represents the file location of the PDF document to convert 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, starting position, and stream length to read.
• Populate the BLOB object by assigning its MTOM field with the contents of the byte array.

Set conversion run-time options.

• Create a ToPSOptionsSpec object by invoking its constructor.
• Set run-time options by assigning a value to the ToPSOptionsSpec object’s data member. For example, to define the PostScript level that is created, assign a PSLevel enumeration value to the ToPSOptionsSpec object’s psLevel data member.

Convert the PDF document to a PostScript file.

Invoke the GeneratePDFServiceService object’s toPS2 method and pass the following values:

• A BLOB object that represents the PDF document to convert to a PostScript file
• A ToPSOptionsSpec object that specifies run-time options

After the conversion is complete, extract the binary data that represents the PostScript document by accessing its BLOB object’s MTOM property. This returns a byte array that you can write out to a PostScript file.

Save the PostScript file.

• Create a System.IO.FileStream object by invoking its constructor. Pass a string value that represents the file location of the PS file.
• Create a byte array that stores the data content of the BLOB object that was returned by the encryptPDFUsingPassword method. Populate the byte array by getting the value of the BLOB object’s MTOM field.
• 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 the PostScript file by invoking the System.IO.BinaryWriter object’s Write method and passing the byte array.

Include project files.

Include client JAR files, such as adobe-convertpdf-client.jar, in your Java project’s class path.

Create a Convert PDF client.

• Create a ServiceClientFactory object that contains connection properties.
• Create a ConvertPdfServiceClient object by using its constructor and passing the ServiceClientFactory object.

Retrieve the PDF document to convert.

• Create a java.io.FileInputStream object that represents the PDF document to convert by using its constructor and passing a string value that specifies the location of the PDF document.
• Create a com.adobe.idp.Document object by using its constructor and passing the java.io.FileInputStream object.

Set run-time options.

• Create a ToImageOptionsSpec object by using its constructor.
• Invoke methods that belong to this object as required. For example, set the image type by invoking the setImageConvertFormat method and passing an ImageConvertFormat enum value that specifies the format type.

NOTE

Setting the ImageConvertFormat enumeration value is mandatory.

Convert the PDF to an image.

Invoke the ConvertPdfServiceClient object’s toImage2 method and pass the following values:

• A com.adobe.idp.Document object that represents the PDF file to convert.
• A com.adobe.livecycle.converpdfservice.client.ToImageOptionsSpec object that contains the various preferences about the target image format.

The toImage2 method returns a java.util.List object that contains images. Each element in the collection is a com.adobe.idp.Document instance.

Retrieve the image files from a collection.

Iterate through the java.util.List object to determine whether images are present. Each element is a com.adobe.idp.Document instance. Save the image by invoking the com.adobe.idp.Document object’s copyToFile method and passing a java.io.File object.
