Conversion of LRAW to OTF

Dear Experts,

I want to convert the data block of type 'LRAW' to 'OTF', so as to generate a PDF document.

Data element of my input data block is 'ORBLK'. I tried some of the function modules 'SX_OBJECT_CONVERT_SCR_OTF', 'CONVERT_OTF' and 'SO_RAW_TO_RTF'. But I could not able to acheive it.

Kindly help me in this regards.

Thanks and Regards,

Arun Prasath.
