Detailed Description

class TK_Font : public BBaseOpcodeHandler

Handles the TKE_Font opcode.

TK_Font provides support for writing/reading the TKE_Font opcode object to/from an HSF file.

The HOOPS/3dGS scene-graph supports user-defined fonts. Refer to the function ::HC_Define_Font in the HOOPS/3dGS Reference Manual

Public Functions

inline TK_Font(): constructor

~TK_Font()

virtual TK_Status Read(BStreamFileToolkit &tk)

Reads data from the toolkit buffer, decodes/decompresses it, and maps it to the opcode handlers data members. User-defined classes which need to write out custom data should utilize one of the available GetData() methods.

Parameters:: tk – A reference to the BStreamFileToolkit object.
Returns:: The result of the function call.

virtual TK_Status Write(BStreamFileToolkit &tk)

Encodes/compresses data and writes data to the toolkit buffer. User-defined classes which need to write out custom data should utilize one of the available PutData() methods, and first write out the opcode associated with the group of binary data followed by the data itself.

Parameters:: tk – A reference to the BStreamFileToolkit object.
Returns:: The result of the function call.

virtual TK_Status Clone(BStreamFileToolkit &tk, BBaseOpcodeHandler **handler) const

Copies the opcode handler

Parameters:

tk – A reference to the BStreamFileToolkit object.
handler – A pointer to the opcode handler object. Passed by reference.

Returns:

The result of the function call.

TK_Status ReadAscii(BStreamFileToolkit &tk): Deprecated.

TK_Status WriteAscii(BStreamFileToolkit &tk): Deprecated.

virtual void Reset(): Resets the current opcode handler. This is called by the toolkit when it is done processing an opcode. This method reinitializes any opcode handler variables and frees up temporary data.

inline void SetType(int t): Set the type of the font (HOOPS stroked font definition is the only one supported so far)

inline int GetType() const: Returns the type of the font

inline void SetBytes(int size, char const *bytes = 0): Sets the font data. Allocates a buffer which can hold ‘size’ bytes, and if specified, copies the data from ‘bytes’ to the buffer

inline int GetBytesCount() const: Returns the size of the data buffer

inline char const *GetBytes() const: Returns the address of the data buffer

inline char *GetBytes(): Returns the address of the data buffer, which may be modified directly

inline void SetName(char const *string): Sets the name of the font. Allocates the buffer and copies the string

inline void SetName(int length): Sets the name buffer. Allocates a buffer large enough to hold a string of ‘length’ characters

inline char const *GetName() const: Returns the font name string

inline char *GetName(): Returns the font name string buffer, which may be modified directly

inline void SetLookup(char const *string): Sets the name of the lookup function. Allocates the buffer and copies the string

inline void SetLookup(int length): Sets the lookup name buffer. Allocates a buffer large enough to hold a string of ‘length’ characters

inline char const *GetLookup() const: Returns the lookup function name string

inline char *GetLookup(): Returns the lookup name string buffer, which may be modified directly

inline void SetEncoding(int e): Set the type of encoding for this font

inline int GetEncoding() const: Returns the type of encoding for this font
