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.
