L_OcrRuntimeFileCallback

Summary

Redirects searching and loading of OCR engine files at runtime to a specified directory or memory buffer.

Syntax

#include "ltocr.h"

L_INT pEXT_CALLBACK YourFunction(engine, runtimeFile, userData)

Parameters

L_OcrEngine * engine

Handle to the OCR engine.

L_OcrRuntimeFile * runtimeFile

Data for the OCR runtime file.

L_VOID * userData

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.
