Class FontBinaryWriter

A big-endian binary writer for OpenType/TrueType font data. All multi-byte integers are written in network byte order (most-significant byte first), as required by the OpenType specification.

Constructors

FontBinaryWriter(Stream, bool)

A big-endian binary writer for OpenType/TrueType font data. All multi-byte integers are written in network byte order (most-significant byte first), as required by the OpenType specification.

Declaration
public FontBinaryWriter(Stream stream, bool leaveOpen = false)
Parameters
Type Name Description
Stream stream

The stream to write to.
bool leaveOpen

When true the underlying stream is NOT disposed when this writer is disposed.

Properties

Position

Current byte position within the underlying stream.

Declaration
public long Position { get; }
Property Value
Type Description
long

Methods

Align4()

Pads the current position forward with zero bytes until the stream position is aligned to a 4-byte boundary. No-op when already aligned. Required by OpenType: every table must begin on a 4-byte boundary.

Declaration
public void Align4()

Dispose()

A big-endian binary writer for OpenType/TrueType font data. All multi-byte integers are written in network byte order (most-significant byte first), as required by the OpenType specification.

Declaration
public void Dispose()

Flush()

Flushes the underlying stream.

Declaration
public void Flush()

Seek(long)

Seeks to an absolute byte offset from the beginning of the stream.

Declaration
public void Seek(long offset)
Parameters
Type Name Description
long offset

WriteBytes(byte[])

Writes a raw byte array verbatim.

Declaration
public void WriteBytes(byte[] data)
Parameters
Type Name Description
byte[] data

WriteF2Dot14(double)

Writes a 2.14 fixed-point number.

Declaration
public void WriteF2Dot14(double value)
Parameters
Type Name Description
double value

WriteFixed(double)

Writes a 16.16 fixed-point number.

Declaration
public void WriteFixed(double value)
Parameters
Type Name Description
double value

WriteInt16(short)

Writes a signed 16-bit integer (big-endian).

Declaration
public void WriteInt16(short value)
Parameters
Type Name Description
short value

WriteInt32(int)

Writes a signed 32-bit integer (big-endian).

Declaration
public void WriteInt32(int value)
Parameters
Type Name Description
int value

WriteInt64(long)

Writes a signed 64-bit integer (big-endian).

Declaration
public void WriteInt64(long value)
Parameters
Type Name Description
long value

WriteTag(string)

Writes a 4-byte ASCII tag. If tag is shorter than 4 characters it is right-padded with spaces; if longer it is truncated.

Declaration
public void WriteTag(string tag)
Parameters
Type Name Description
string tag

WriteUInt16(ushort)

Writes an unsigned 16-bit integer (big-endian).

Declaration
public void WriteUInt16(ushort value)
Parameters
Type Name Description
ushort value

WriteUInt32(uint)

Writes an unsigned 32-bit integer (big-endian).

Declaration
public void WriteUInt32(uint value)
Parameters
Type Name Description
uint value

WriteUInt8(byte)

Writes one unsigned byte.

Declaration
public void WriteUInt8(byte value)
Parameters
Type Name Description
byte value
