The Output API was completely re-written in the ImageGear Recognition Component for v17. The output is now available in two options:
Functions IG_REC_output_convert_to_doc, IG_REC_RDFile_write, IG_REC_output_text_get, and IG_REC_output_text_delete have been removed from the API. Functions IG_REC_output_format_get/ IG_REC_output_format_set are now applicable for document output only.
Identifying names of the output formats has changed. For example: "CSV" -> "Converters.Text.Csv". All supported document output formats can be still queried using IG_REC_output_format_first_get/ IG_REC_output_format_next_get functions.
See Exporting Recognized Data Directly to Text Formats and Exporting to a Formatted Output Document for more details.
