/images/arrow_right.png Calling argument description
[out] BSTR *pbstrFile *pbstrFile supplies the full file name (path + name) of the document in a temporary working directory.
Be sure to copy away the file to a different location as all files in the working directory are deleted before the COM module shuts down!

In Restful Webservice output: pbstrFile is a relative URL that subsequently must be downloaded by a GET process.

[out] BSTR *pbstrTitle The title of the document on the primary system. It thus describes the document to a certain degree in terms of its semantic content.
[out] BSTR *pbstrMimeType The MIME type of the document.

Since the underlying XSD schema restricts the type of files, the MIME type must be one of

  • application/pdf for PDF files
  • image/jpeg for JPG graphic files
  • image/png for PNG graphic files
[out,retval] VARIANT_BOOL *pbStatus Return status of the method. If pbStatus is VARIANT_FALSE the end of data is reached
