PROGRESSDATA

typedef struct _tagProgressData
{
   L_UINT uStructSize;
   OCRPROCID Id;
   L_INT nPercent;
   L_INT nAccecptCharCount;
   L_INT nRejectedCharCount;
   L_INT32 lObjSize;
   L_UCHAR *uObjData;
} PROGRESSDATA, * pPROGRESSDATA;

The PROGRESSDATA structure is used by the PROGRESSCALLBACK function.

Member	Description
uStructSize	Structure size. It should be equal to sizeof(PROGRESSDATA).
Id	Identifier of the process currently running. For a list of possible values, refer to OCRPROCID.
nPercent	Progress of the current process expressed as a percentage
nAccecptCharCount	Number of recognized characters accepted during the recognition process.
nRejectedCharCount	Number of characters rejected during the recognition process
lObjSize	Size of the uObjData buffer containing the real time information
uObjData	Sample text from the recognized characters (typically 30-80 chars) in UNICODE for real-time information.

Comments

The uObjSize and uObjData fields are also recognition specific fields. They serve for real time display purposes. These fields are applicable only if the Id member is PROC_RECOGNITION.

The nAccecptCharCount and nRejectedCharCount fields are recognition specific fields. They are applicable only if the Id member is PROC_RECOGNIZE_MOR, PROC_RECOGNITION or PROC_RECOGNITION3.

pPROGRESSDATA is a pointer to a PROGRESSDATA structure. If the function parameter type is pPROGRESSDATA, declare a PROGRESSDATA variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pPROGRESSDATA variable is necessary only if the program requires a pointer.

This structure will be filled only when PROGRESSCALLBACK is called. The PROGRESSCALLBACK function will be called if you have set a callback function with L_DocSetProgressCB.
