Property Value

EXIF information often contains a small thumbnail image. That image can be obtained from this property. The thumbnail can also be set or changed by setting this to a new stream.

Please note that saving a thumbnail inside a TIFF image requires that the thumbnail is a TIFF. When copying EXIF from a JPEG to a TIFF, ensure that the ThumbnailStream is converted from a JPEG to a TIFF.
