Method Summary

Modifier and Type	Method and Description
int	compareTo(TiffDataType obj) Compares the current instance with another object of the same type and returns an integer that indicates whether the current instance precedes, follows, or occurs in the same position in the sort order as the other object.

boolean	equals(Object obj)
long	getAdditionalDataSize(byte sizeOfTagValue) Gets the additional tag value size in bytes (in case the tag can not fit the whole tag value).
long	getAlignedDataSize(byte sizeOfTagValue) Gets the data size aligned in 4-byte (int) or 8-byte (long) boundary.
abstract long	getCount() Gets the count of elements.
long	getDataSize() Gets the tag value size.
byte	getElementSize() Gets the element size in bytes.
int	getId() Gets tag id as number.
int	getTagId() Gets the tag id.
abstract int	getTagType() Gets the tag type.
abstract Object	getValue() Gets the value this data type contains.
int	hashCode()
boolean	isValid() Gets a value indicating whether tag data is valid.
static TiffDataType	readTag(TiffStreamReader dataStream, long position) Reads the tag data.
abstract void	setValue(Object value) Sets the value this data type contains.
String	toString() Returns a System.String that represents this instance.
abstract long	writeAdditionalData(TiffStreamWriter dataStream) Writes the additional tag data.

Method Detail

getElementSize

public byte getElementSize()

Gets the element size in bytes.

Returns:

the element size in bytes.

getDataSize

public long getDataSize()

Gets the tag value size.

Returns:

the tag value size.

getCount

public abstract long getCount()

Gets the count of elements.

Value: The count of elements.

Returns:

the count of elements.

getId

public final int getId()

Gets tag id as number.

Returns:

tag id as number.

getTagId

public int getTagId()

Gets the tag id.

Returns:

The tag id.

getTagType

public abstract int getTagType()

Gets the tag type.

Returns:

The tag type.

getAlignedDataSize

public final long getAlignedDataSize(byte sizeOfTagValue)

Gets the data size aligned in 4-byte (int) or 8-byte (long) boundary.

Parameters:

sizeOfTagValue - Size of tag value.

Returns:

The aligned data size in bytes.

getAdditionalDataSize

public long getAdditionalDataSize(byte sizeOfTagValue)

Gets the additional tag value size in bytes (in case the tag can not fit the whole tag value).

Parameters:

Parameters:

value - The value.

isValid

public boolean isValid()

Gets a value indicating whether tag data is valid. The valid tag contains data which may be preserved. The invalid tag cannot be stored.

Returns:

true if tag data is valid; otherwise, false.

readTag

public static TiffDataType readTag(TiffStreamReader dataStream,
                                   long position)

Parameters:

dataStream - The data stream.

position - The tag position.

Returns:

The read tag.

Throws:

com.aspose.ms.System.ArgumentNullException - dataStream

compareTo

public int compareTo(TiffDataType obj)

Compares the current instance with another object of the same type and returns an integer that indicates whether the current instance precedes, follows, or occurs in the same position in the sort order as the other object.

Specified by:

compareTo in interface Comparable<TiffDataType>

Parameters:

obj - An object to compare with this instance.

Returns:

A 32-bit signed integer that indicates the relative order of the objects being compared. The return value has these meanings: Value Meaning Less than zero This instance is less than obj. Zero This instance is equal to obj. Greater than zero This instance is greater than obj.

Throws:

TiffImageException - Expected TiffDataType type.
