OCR of PDF-documents using GData

Ruby

Hi,

Has anybody been able to perform OCR on a pdf document using GData?

http://googledataapis.blogspot.com/2009/09/import-scans-or-go-multilingual.html

Png and jpgs work fine after setting @client.version = ‘3’ in
GData::Client::DocList but when I try pdf-files I get:

#<GData::Client::BadRequestError: request error 400:

GData
InvalidEntryException
Could not convert document.

Regards,
Abigail
