Combines multiple PDF files into a single PDF file. Allows specifying which pages of the source files to combine.

Sample Usage:



 const credentials = DCServicesSdk.Credentials.serviceAccountCredentialsBuilder()
           .fromFile("dc-services-sdk-credentials.json")
           .build(),
       executionContext = DCServicesSdk.ExecutionContext.create(credentials),
       combineFilesOperation = DCServicesSdk.CombineFiles.Operation.createNew(),
       input1 = DCServicesSdk.FileRef.createFromLocalFile('test/resources/combinePagesInput1.pdf'),
       input2 = DCServicesSdk.FileRef.createFromLocalFile('test/resources/combinePagesInput1.pdf'),

 combineFilesOperation.addInput(input1);
 combineFilesOperation.addInput(input2);

 combineFilesOperation.execute(executionContext)
     .then(result => result.saveAsFile('output/CombinedPDF.pdf'))
     .catch(err => console.log(err));

execute(contextnon-null) → {Promise.<FileRef>}

Executes this operation using the supplied context and returns a Promise which resolves to the operation result.

The resulting file may be stored in the system temporary directory (per the os.tempdir(), symlinks are resolved to the actual path). See FileRef for how temporary resources are cleaned up.
