Parameters

Return Value

A boolean value indicating whether processing should continue for this job (true = continue processing; false = stop processing).

A value of false indicates the job was either aborted or deleted by an administrator or client.

Failure to update the progress can cause the windows service to assume the process is hung. This will result in the OnJobTerminated method to be called and the process will be terminated.

Progress should be posted at the interval specified by the percentage parameter.

If an empty string is passed for the workerMetadata parameter, the existing worker metadata for the job is maintained. For more information on how the workerMetadata property is used, refer to Understanding The LEADTOOLS Job Processor Database.

Refer to the OCRJobProcessorDemo. Depending on the programming language being used, the demo will be found in either the <installationdir>\Examples\DotNet\CS\OCRJobProcessorDemo directory. or the <installationdir>\Examples\DotNet\VB\OCRJobProcessorDemo directory. The <installationdir> represents the directory in which you installed the LEADTOOLS toolkit.
