Reader provides common functionality for reading underlying DICOM data.

func NewReader

func NewReader(in *bufio.Reader, bo binary.ByteOrder, limit int64) (Reader, error)

NewReader creates and returns a new dicomio.Reader.

type Writer

type Writer struct {
	// contains filtered or unexported fields
}

Writer is a lower level encoder that manages writing out entities to an io.Reader.

func NewWriter

func NewWriter(out io.Writer, bo binary.ByteOrder, implicit bool) Writer

NewWriter initializes and returns a Writer.

func (*Writer) GetTransferSyntax

func (w *Writer) GetTransferSyntax() (binary.ByteOrder, bool)

GetTransferSyntax gets the current transfer syntax of this Writer.

func (*Writer) SetTransferSyntax

func (w *Writer) SetTransferSyntax(bo binary.ByteOrder, implicit bool)

SetTransferSyntax sets the current transfer syntax of this Writer.

func (*Writer) WriteByte

func (w *Writer) WriteByte(v byte) error

WriteByte writes the provided byte to the Writer.

func (*Writer) WriteBytes

func (w *Writer) WriteBytes(v []byte) error

WriteBytes writes the provided byte slice to the Writer.

WriteFloat32 writes the provided float32 to the Writer.

func (*Writer) WriteFloat64

func (w *Writer) WriteFloat64(v float64) error

WriteFloat64 writes the provided float64 to the Writer.

func (*Writer) WriteString

func (w *Writer) WriteString(v string) error

WriteString writes the provided string to the Writer.

func (*Writer) WriteUInt16

func (w *Writer) WriteUInt16(v uint16) error

WriteUInt16 writes the provided uint16 to the Writer.

func (*Writer) WriteUInt32

func (w *Writer) WriteUInt32(v uint32) error

WriteUInt32 writes the provided uint32 to the Writer.

func (*Writer) WriteZeros

func (w *Writer) WriteZeros(len int) error

WriteZeros writes len bytes of zeros at the current position of the Writer.
