## Detailed Description

class `TK_Texture` : public BBaseOpcodeHandler

  Handles the TKE_Texture opcode.

  TK_Texture provides support for writing/reading the TKE_Texture opcode object to/from an HSF file.

  The HOOPS/3dGS scene-graph supports ‘textures’, which define an image that can be applied to a HOOPS/3dGS shell or mesh primitive.

  Subclassed by HTK_Texture

  Public Functions

  inline `TK_Texture`()

    constructor

  `~TK_Texture`()
  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`()

    Returns the texture name

  inline char *`GetName`()

    Returns the texture name buffer, which can be modified directly

  void `SetShaderSource`(char const *shader_source)

    Sets the texture shader source. Allocates the buffer and copies the shader source string

  void `SetShaderSource`(int length)

    Sets the texture shader source buffer. Allocates a buffer large enough to hold a string of ‘length’ characters
