Constructor Detail

OtherByteAttributeMultipleCompressedFrames

public OtherByteAttributeMultipleCompressedFrames(AttributeTag t,
                                          byte[][] frames)

Construct an attribute from a set of compressed frames.

The VL is not required, since it is undefined by definition.

Parameters:

t - the tag of the attribute

frames - the frames

OtherByteAttributeMultipleCompressedFrames

public OtherByteAttributeMultipleCompressedFrames(AttributeTag t,
                                          java.io.File[] files)

Construct an attribute from a set of compressed frames.

The VL is not required, since it is undefined by definition.

Parameters:

t - the tag of the attribute

files - the files containing the compressed bit streams

Method Detail

writeItemTag

protected void writeItemTag(DicomOutputStream o,
                long length)
                     throws java.io.IOException

Throws:

java.io.IOException

writeSequenceDelimitationItemTag

protected void writeSequenceDelimitationItemTag(DicomOutputStream o)
                                         throws java.io.IOException

Throws:

java.io.IOException

write

public void write(DicomOutputStream o)
           throws DicomException,
                  java.io.IOException

Description copied from class: Attribute

Write the entire attribute (including values) to the output stream.

Specified by:

write in class Attribute

Parameters:

o -

Throws:

java.io.IOException

DicomException - if no byte array or files containing the compressed bitstream have been supplied

getFrames

public byte[][] getFrames()

Get the byte arrays for each frame.

Returns:

an array of byte arrays for each frame

toString

public java.lang.String toString(DicomDictionary dictionary)

Description copied from class: Attribute

Dump the contents of the attribute as a human-readable string.

No new line is appended.

The result is of the form:

 (0xgggg,0xeeee) Name VR=<XX> VL=<0xnnnn> <...>
 

For example:

 (0x0018,0x0020) ScanningSequence VR=<CS> VL=<0x2> <GR>
 

Overrides:

toString in class Attribute

Parameters:

dictionary - the dictionary to use to look up the name

Returns:

a single String value

removeValues

public void removeValues()

Description copied from class: Attribute

Remove any existing values, making the attribute empty (zero length).

Specified by:

removeValues in class Attribute

Throws:

DicomException

getVR

public byte[] getVR()

Get the value representation of this attribute (OB).

Overrides:

getVR in class Attribute

Returns:

'O','B' in ASCII as a two byte array; see ValueRepresentation
