This function appends two document files (usually have the LTD extension) which you previously created by calling L_OcrDocumentManager_CreateDocument. For more information on creating OCR document files, refer to L_OcrDocumentManager_CreateDocument.
After appending the document files you can load the destination document into OCR engine again by calling L_OcrDocumentManager_CreateDocument passing L_OcrCreateDocumentOptions_LoadExisting to its 'options' parameter and the dstFileName to its 'fileName' parameter then you can save it to any of LEADTOOLS supported document formats like PDF, DOC, DOCX, TXT, and many other formats. Or you can convert the destination document directly to any of the LEADTOOLS supported document formats by calling L_DocWriterConvert.
