Example

This example shows how to acquire a colored image.

L_INT AcquireImage(L_SaneHandle hSane, pBITMAPHANDLE bitmap) 
{ 
   // Get the scanning mode value 
   L_TCHAR* value = NULL; 
   L_INT ret = L_SaneGetOptionValue(hSane, SANE_NAME_SCAN_MODE, &value); 
   if(ret != SUCCESS) 
      return ret; 
   if(strcmp(value, SANE_VALUE_SCAN_MODE_COLOR) != 0) 
   { 
      // Set the scanning mode to "Color" 
      ret = L_SaneSetOptionValue(hSane, SANE_NAME_SCAN_MODE, SANE_VALUE_SCAN_MODE_COLOR); 
   } 
   // Free the value buffer 
   L_SaneFreeMemory(value); 
   // Scan an image 
   return L_SaneAcquire(hSane, bitmap, sizeof(BITMAPHANDLE)); 
}
