public:
virtual void SaveSettingsToFile(
String^ targetFile,
ConvertSettings flags
)
targetFile
The file in which settings will be saved.
flags
The settings flags specifying which settings to save. See the ConvertSettings enumeration for settings options.
The convert object settings can be saved to a stream by calling SaveSettingsToStream. Saved settings can be loaded using the LoadSettingsFromFile method or the LoadSettingsFromStream method. It may be helpful to call the CanSaveObjectSettings method before calling the save methods. This ensures the settings can be saved. If either SaveSettingsToFile or SaveSettingsToStream is called for settings that cannot be saved, the save method fails.
