개별 메타파일 레코드를 재생합니다.

public:
 void PlayRecord(System::Drawing::Imaging::EmfPlusRecordType recordType, int flags, int dataSize, cli::array <System::Byte> ^ data);

public void PlayRecord (System.Drawing.Imaging.EmfPlusRecordType recordType, int flags, int dataSize, byte[] data);

member this.PlayRecord : System.Drawing.Imaging.EmfPlusRecordType * int * int * byte[] -> unit

Public Sub PlayRecord (recordType As EmfPlusRecordType, flags As Integer, dataSize As Integer, data As Byte())

매개 변수

recordType

EmfPlusRecordType

재생할 메타파일 레코드의 형식을 지정하는 EmfPlusRecordType의 요소입니다.

flags

Int32

레코드의 특성을 지정하는 플래그 집합입니다.

dataSize

Int32

레코드 데이터의 바이트 수입니다.

data

Byte[]

레코드 데이터가 포함된 바이트 배열입니다.
