Configure OCR
In the following examples, OCR is configured to process scanned pages that contain only English or only Japanese text. Providing information about the input can result in a performance improvement, but OCR may fail to recognize text that does not match your configuration. For more information about optimizing OCR, see Optimize OCR Performance.
To configure OCR
-
To configure OCR through the C API, create a KVOcrOptions structure and then call fpSetConfig() and set the KVFLT_OCR option.
CopyKVOcrOptions options;
KVStructInit(&options);
options.textFindingMode = KVOcrDocument;
options.languages = "en ja";
options.orientation = KVOcrUpright;
options.detectAlphabet = KVOcrListed;
