OCR multiple pages of multiple PDF documents.
This function can be used to batch process multiple documents or pages. Users can set documents and page ranges via OCRSettingDataArray. The time performance of this function will be better than calling OCRPDFDocument or OCRPDFPage when dealing with a large number of documents or pages. And it will cost a lot of memory as well. After this function succeeds, the PDF page content may be changed. it is better to parse or re-parse PDF pages before using these pages.
[in] | settingdata_array | An array of OCRSettingData objects, if the parameter page_range is empty, it will default to all pages of the OCR document. |
