Comments

The convert object's settings can be saved to a file by calling IltmmConvert::SaveSettingsToFile.

Settings that have been saved to a file can be loaded using IltmmConvert::LoadSettingsFromFile. Settings that have been saved to a stream can be loaded using IltmmConvert::LoadSettingsFromStream.

It may be helpful to call IltmmConvert::CanSaveObjectSettings before calling either IltmmConvert::SaveSettingsToFile or [IltmmConvert:SaveSettingsToStream, to make sure the settings you want to save can be saved. If either IltmmConvert::SaveSettingsToFile or IltmmConvert::SaveSettingsToStream is called for settings that cannot be saved, the save function will fail.
