WTS_CONTEXTFLAGS enumeration (thumbcache.h)

  • Article

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.

  WTSCF_DEFAULT = 0,
  WTSCF_APPSTYLE = 0x1,
  WTSCF_SQUARE = 0x2,
  WTSCF_WIDE = 0x4,
  WTSCF_FAST = 0x8
} ;
