   ILeadStream^ stream 
)

Parameters

stream
A ILeadStream containing the image data to query.

Return Value

The format of the image.

Remarks

GetInformationAsync and GetFormatAsync use GetInformationAsync internally. So, if more information about the image is required, it is recommended to call GetInformationAsync directly and obtain the data once.

Example

For an example, refer to Load(Stream stream, int pageNumber).
