FieldValue¶
Namespace: ThinkGeo.Core.LibTiff
Holds a value of a Tiff tag.
public struct FieldValue
Inheritance Object → ValueType → FieldValue
Remarks:
Simply put, it is a wrapper around System.Object, that helps to deal with unboxing and conversion of types a bit easier.

Remarks:
If value is a byte array, then it gets converted to string using Latin1 encoding encoder.
GetBytes()¶
Retrieves value converted to byte array.
Byte[] GetBytes()
Returns¶
Byte[]
Value converted to byte array.
Remarks:
If value is byte array then it retrieved unaltered.
If value is array of short, ushort, int, uint, float or double values then this array is converted to byte array
If value is a string then it gets converted to byte array using Latin1 encoding encoder.
If value is of any other type then null is returned.
ToByteArray()¶
Retrieves value converted to array of bytes.
Byte[] ToByteArray()
Returns¶
Byte[]
Value converted to array of bytes.
Remarks:
If value is array of bytes then it retrieved unaltered.
If value is array of short, ushort, int or uint values then each element of field value gets converted to byte and added to resulting array.
If value is string then it gets converted to byte[] using Latin1 encoding encoder.
If value is of any other type then null is returned.
ToShortArray()¶
Retrieves value converted to array of short values.
Int16[] ToShortArray()
Returns¶
Int16[]
Value converted to array of short values.
Remarks:
If value is array of short values then it retrieved unaltered.
If value is array of bytes then each pair of bytes is converted to short and added to resulting array. If value contains odd amount of bytes, then null is returned.
If value is array of ushort, int or uint values then each element of field value gets converted to short and added to resulting array.
If value is of any other type then null is returned.
ToUShortArray()¶

UInt16[] ToUShortArray()
Returns¶
UInt16[]
Value converted to array of ushort values.
Remarks:
If value is array of ushort values then it retrieved unaltered.
If value is array of bytes then each pair of bytes is converted to ushort and added to resulting array. If value contains odd amount of bytes, then null is returned.
If value is array of short, int or uint values then each element of field value gets converted to ushort and added to resulting array.
If value is of any other type then null is returned.

Int32[] ToIntArray()
Returns¶
Int32[]
Value converted to array of int values.
Remarks:
If value is array of int values then it retrieved unaltered.
If value is array of bytes then each 4 bytes are converted to int and added to resulting array. If value contains amount of bytes that can't be divided by 4 without remainder, then null is returned.
If value is array of short, ushort or uint values then each element of field value gets converted to int and added to resulting array.
If value is of any other type then null is returned.
ToUIntArray()¶
Retrieves value converted to array of uint values.
UInt32[] ToUIntArray()
Returns¶
UInt32[]
Value converted to array of uint values.
Remarks:
If value is array of uint values then it retrieved unaltered.
If value is array of bytes then each 4 bytes are converted to uint and added to resulting array. If value contains amount of bytes that can't be divided by 4 without remainder, then null is returned.
If value is array of short, ushort or int values then each element of field value gets converted to uint and added to resulting array.
If value is of any other type then null is returned.
TolongArray()¶
Retrieves value converted to array of long values.
Int64[] TolongArray()
Returns¶
Int64[]
Value converted to array of long values.
Remarks:
If value is array of long values then it retrieved unaltered.
If value is array of bytes then each 8 bytes are converted to uint and added to resulting array. If value contains amount of bytes that can't be divided by 8 without remainder, then null is returned.
If value is array of short, ushort or int values then each element of field value gets converted to long and added to resulting array.
