IMcImageStorageOpenStorage Method

Sub OpenStorage ( 
	ImageType As McImageType,
	Width As Integer,
	Height As Integer,
	FrameCount As Integer,
	StartingFrameIndex As Integer
)

The method takes no storage information (e.g., a file name), since each McImageStorage is responsible for knowing where its own storage is located. Always check IsStorageOpen before calling Open, since some instances of McImageStorage may already have been opened. In this case, you can find the type of storage by calling NaturalImageType and the dimensions of the storage by calling the GetDimensions method. If the mciscCanExtendSize Capabilities property bit is set, then OpenStorage can be called with a FrameCount larger than the existing frame count as returned by GetStorageDimension. In this case, the ImageType, Width and Height arguments are ignored; it is the caller's responsibility to ensure that the frames the storage is being extended for are of the same type and dimensions as those specified in the original call to OpenStorage. Call CloseStorage when you are through with it, and before you try to reopen the storage for fresh use.
