Handles the TKE_Clip_Region opcodes.
TK_Clip_Region provides support for writing/reading the TKE_Clip_Region opcode to/from an HSF file. A clip region defines a clip region which should be applied to the contents of the current segment and all subsegments (just like any HOOPS/3dGS attribute)
TK_Clip_Region::TK_Clip_Region | ( | ) | [inline] |
constructor
TK_Status TK_Clip_Region::Clone | ( | BStreamFileToolkit & | tk, |
BBaseOpcodeHandler ** | handler | ||
) | const [virtual] |
Copies the opcode handler
tk | A reference to the BStreamFileToolkit object. |
handler | A pointer to the opcode handler object. Passed by reference. |
Reimplemented from BBaseOpcodeHandler.
Reimplemented in HTK_Clip_Region.
int TK_Clip_Region::GetCount | ( | ) | const [inline] |
Returns the number of points in the buffer
double const* TK_Clip_Region::GetDPoints | ( | ) | const [inline] |
Returns the address of the point buffer
double* TK_Clip_Region::GetDPoints | ( | ) | [inline] |
Returns the address of the point buffer, which may be modified directly
int TK_Clip_Region::GetOptions | ( | ) | const [inline] |
Returns the option flags
float const* TK_Clip_Region::GetPoints | ( | ) | const [inline] |
Returns the address of the point buffer
float* TK_Clip_Region::GetPoints | ( | ) | [inline] |
Returns the address of the point buffer, which may be modified directly
TK_Status TK_Clip_Region::Read | ( | BStreamFileToolkit & | tk | ) | [virtual] |
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.
tk | A reference to the BStreamFileToolkit object. |
Implements BBaseOpcodeHandler.
void TK_Clip_Region::Reset | ( | ) | [virtual] |
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.
Reimplemented from BBaseOpcodeHandler.
void TK_Clip_Region::SetDPoints | ( | int | count, |
double const | points[] = 0 |
||
) |
Sets the point array. Allocates a buffer which will hold 'count' double triplets, and if specified, copies the 'points' into the buffer
void TK_Clip_Region::SetOptions | ( | int | o | ) | [inline] |
Sets the option flags
void TK_Clip_Region::SetPoints | ( | int | count, |
float const | points[] = 0 |
||
) |
Sets the point array. Allocates a buffer which will hold 'count' float triplets, and if specified, copies the 'points' into the buffer
TK_Status TK_Clip_Region::Write | ( | BStreamFileToolkit & | tk | ) | [virtual] |
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.
tk | A reference to the BStreamFileToolkit object. |
Implements BBaseOpcodeHandler.
