The TmsScrollImage component is designed to make it simple to load data at design time and then be able to use that data at runtime without having to worry about creating resource files and then having to including them as part of the form.
Set this property at designtime to the file that should be saved as a resource. Attempting to change this property at runtime will have no effect on the component or resource.
procedure msResourceItem.SaveToFile(Const FileName: TFileName);
Call the SaveToFile function at runtime to save the resource associated with the component to the filename you specify when calling the SaveToFile function.
procedure msResourceItem.SaveToStream(s: TStream);
Call the SaveToStream function at runtime to save the resource associated with the component to the Tstream specified when calling the save to stream function.
