Member Function Documentation

vtkPVCompositeUtilities* vtkPVCompositeUtilities::New (   )  [static]

vtkPVCompositeUtilities::vtkTypeRevisionMacro (  vtkPVCompositeUtilities  , vtkObject  )

void vtkPVCompositeUtilities::PrintSelf (  ostream &  os, vtkIndent  indent )

vtkFloatArray* vtkPVCompositeUtilities::NewFloatArray (  int  numTuples, int  numComponents )

Get a data array of the specified size and type. This will be used to get z and color buffers.

vtkUnsignedCharArray* vtkPVCompositeUtilities::NewUnsignedCharArray (  int  numTuples, int  numComponents )

Get a data array of the specified size and type. This will be used to get z and color buffers.

vtkPVCompositeBuffer* vtkPVCompositeUtilities::NewCompositeBuffer (  int  numPixels  )

This will return a special object to hold a compressed buffer.

vtkPVCompositeBuffer* vtkPVCompositeUtilities::NewCompositeBuffer (  vtkUnsignedCharArray *  pData, vtkFloatArray *  zData )

This is used to create a buffer when not using compositing.

void vtkPVCompositeUtilities::SendBuffer (  vtkMultiProcessController *  controller, vtkPVCompositeBuffer *  buf, int  otherProc, int  tag )  [static]

Send a buffer in one easy call.

vtkPVCompositeBuffer* vtkPVCompositeUtilities::ReceiveNewBuffer (  vtkMultiProcessController *  controller, int  otherProc, int  tag )

Receive a buffer in one easy call. The caller is responsible for deleting the returned buffer.

void vtkPVCompositeUtilities::Compress (  vtkFloatArray *  zIn, vtkUnsignedCharArray *  pIn, vtkPVCompositeBuffer *  outBuf )  [static]

I am granting access to these methods and making them static So I can create a TileDisplayCompositer which uses compression.

int vtkPVCompositeUtilities::GetCompressedLength (  vtkFloatArray *  zIn  )  [static]

This method predicts the length of a compressed buffer. It is used to get the best size array for compressed buffer.

void vtkPVCompositeUtilities::Uncompress (  vtkPVCompositeBuffer *  inBuf, vtkUnsignedCharArray *  pOut )  [static]

int vtkPVCompositeUtilities::GetCompositedLength (  vtkPVCompositeBuffer *  b1, vtkPVCompositeBuffer *  b2 )  [static]

This method returns a conservative guess at the output length after two bufferes are composited.

void vtkPVCompositeUtilities::CompositeImagePair (  vtkPVCompositeBuffer *  inBuf1, vtkPVCompositeBuffer *  inBuf2, vtkPVCompositeBuffer *  outBuf )  [static]

void vtkPVCompositeUtilities::MagnifyBuffer (  vtkDataArray *  in, vtkDataArray *  out, int  inWinSize[2], int  factor )  [static]

virtual void vtkPVCompositeUtilities::SetMaximumMemoryUsage (  unsigned  long  )  [virtual]

The maximum amount of memory (kB) that the buffers can use. If this value is set too low, then memory will be reallocated as needed.

virtual unsigned long vtkPVCompositeUtilities::GetMaximumMemoryUsage (   )  [virtual]

The maximum amount of memory (kB) that the buffers can use. If this value is set too low, then memory will be reallocated as needed.

unsigned long vtkPVCompositeUtilities::GetTotalMemoryUsage (   )

Access for debugging purposes.

int vtkPVCompositeUtilities::RemoveOldestUnused (  vtkCollection *  arrayCollection  )  [protected]
