Public Methods

Method	Description
IFDRenderer ( bool is_bigendian, IFDStructure structure, uint ifd_offset ) : System	Constructor. Will render the given IFD structure.
Render ( ) : ByteVector	Renders the current instance to a ByteVector.

Protected Methods

Method	Description
CreateSubRenderer ( bool is_bigendian, IFDStructure structure, uint ifd_offset ) : IFDRenderer	Constructs a new IFD Renderer used to render a SubIFDEntry.
RenderEntry ( ByteVector entry_data, ushort tag, ushort type, uint count, uint offset ) : void	Adds the data of a single entry to entry_data.
RenderEntryData ( IFDEntry entry, ByteVector entry_data, ByteVector offset_data, uint data_offset ) : void	Renders a complete entry together with the data. The entry itself is stored in entry_data and the data of the entry is stored in offset_data if it cannot be stored in the offset. This method is called for every of this IFD and can be overwritten in subclasses to provide special behavior.

Private Methods

Method	Description
RenderIFD ( IFDDirectory directory, uint ifd_offset, bool last ) : ByteVector	Renders the IFD to an ByteVector where the offset of the IFD itself is ifd_offset and all offsets contained in the IFD are adjusted accroding it.

Method Details

CreateSubRenderer() protected method

Constructs a new IFD Renderer used to render a SubIFDEntry.

protected CreateSubRenderer ( bool is_bigendian, IFDStructure structure, uint ifd_offset ) : IFDRenderer
is_bigendian	bool	/// If IFD should be encoded in BigEndian or not. ///
structure	IFDStructure	/// The IFD structure that will be rendered. ///
ifd_offset	uint	/// A value with the offset of the /// current IFD. All offsets inside the IFD must be adjusted /// according to this given offset. ///
return	IFDRenderer

IFDRenderer() public method

Constructor. Will render the given IFD structure.

public IFDRenderer ( bool is_bigendian, IFDStructure structure, uint ifd_offset ) : System
is_bigendian	bool	/// If IFD should be encoded in BigEndian or not. ///
structure	IFDStructure	/// The IFD structure that will be rendered. ///
ifd_offset	uint	/// A value with the offset of the /// current IFD. All offsets inside the IFD must be adjusted /// according to this given offset. ///
return	System

Render() public method

Renders the current instance to a ByteVector.

public Render ( ) : ByteVector
return	ByteVector

RenderEntry() protected method

Adds the data of a single entry to entry_data.

protected RenderEntry ( ByteVector entry_data, ushort tag, ushort type, uint count, uint offset ) : void
entry_data	ByteVector	/// A to add the entry to. ///
tag	ushort	/// A with the tag of the entry. ///
type	ushort	/// A with the type of the entry. ///
count	uint	/// A with the data count of the entry, ///
offset	uint	/// A with the offset field of the entry. ///
return	void

RenderEntryData() protected method

Renders a complete entry together with the data. The entry itself is stored in entry_data and the data of the entry is stored in offset_data if it cannot be stored in the offset. This method is called for every of this IFD and can be overwritten in subclasses to provide special behavior.

protected RenderEntryData ( IFDEntry entry, ByteVector entry_data, ByteVector offset_data, uint data_offset ) : void
entry	IFDEntry	/// A with the entry to render. ///
entry_data	ByteVector	/// A to add the entry to. ///
offset_data	ByteVector	/// A to add the entry data to if it cannot be /// stored in the offset field. ///
data_offset	uint	/// A with the offset, were the data of the /// entries starts. It is needed to adjust the offsets of the entries /// itself. ///
return	void
