Example

This example loads a bitmap and detects glare zone.

L_INT GlareDetectionExample(L_VOID) 
{ 
    L_INT nRet; 
    BITMAPHANDLE LeadBitmap;   /* Bitmap handle to hold the loaded image. */ 
    /* Load the bitmap, keeping the bits per pixel of the file */ 
    nRet = L_LoadBitmap (MAKE_IMAGE_PATH(TEXT("Glare.jpg")), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL); 
    if( nRet != SUCCESS ) 
        return nRet ; 
 
    /* Apply Glare detection filter */ 
    nRet = L_GlareDetection(&LeadBitmap) ; 
    if (nRet == SUCCESS) 
    { 
        nRet = L_SaveBitmap(MAKE_IMAGE_PATH(TEXT("Result.BMP")), &LeadBitmap, FILE_BMP, 24, 0, NULL); 
    } 
 
    //free bitmap 
    if(LeadBitmap.Flags.Allocated)
