WTS_CONTEXTFLAGS enumeration (thumbcache.h)
Specifies the context of a thumbnail extraction. Used by IThumbnailSettings::SetContext.
Your thumbnail provider will set this flag based on the WTS_FLAGS values that it received through the IThumbnailProvider::GetThumbnail request.
Syntax
typedef enum WTS_CONTEXTFLAGS {
WTSCF_DEFAULT = 0,
WTSCF_APPSTYLE = 0x1,
WTSCF_SQUARE = 0x2,
WTSCF_WIDE = 0x4,
WTSCF_FAST = 0x8
} ;
