Comments

This callback function will be enabled only if you enabled the callback functions by calling LBase::EnableCallBack(TRUE). You must handle the image during this callback.

To prevent memory leaks, the user should free the bitmap within the callback function.

The LTwain::GetExtendedImageInfo function can only be called within [LTwain:BitmapCallBack.
