L_INT pEXT_CALLBACK YourFunction(engine, runtimeFile, userData)
Redirects searching and loading of OCR engine files at runtime to a specified directory or memory buffer.
Handle to the OCR engine.
Data for the OCR runtime file.
A void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the userData
parameter of the L_OcrEngine_SetRuntimeFileCallback function).
Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
