   LPAFT_IG_ICC_SET_CB lpfnSetCB,
   LPAFT_ANY lpfnReserved
);

Arguments:

Name Type Description
lpPrivate LPVOID Private callback data.
lpfnGetCB LPAFT_IG_ICC_GET_CB GET callback function.
lpfnSetCB LPAFT_IG_ICC_SET_CB SET callback function.
lpfnReserved LPAFT_ANY Reserved.

Sample:

Load Callback

Example:

 
Copy Code
VOID ACCUAPI ICCGet(
   AT_VOID       *lpPrivate,        // Private callback data.
   AT_BYTE       *lpICCData,        // ICC profile data, allocated by the toolkit
   AT_INT         DataLength        // Length of ICC profile data, in bytes
)
{
    // ...
}

VOID ACCUAPI ICCSet(
   AT_VOID       *lpPrivate,        // Private callback data.
   AT_BYTE       **lplpICCData,        // ICC profile data, allocated by the application
   AT_INT        *lpDataLength        // Length of ICC profile data, in bytes
)
{
    // ...
}

void Example_IG_fltr_ICC_callback_set()
{
    AT_ERRCOUNT nErrcount;            // Count of returned errors on stack
    // Set ICC callback functions
    nErrcount = IG_fltr_ICC_callback_set(NULL, ICCGet, ICCSet, NULL);
}

Remarks:

This function registers callbacks for reading and writing ICC profiles during loading and saving of image files.
