Member Function Documentation

vtkWin32VideoSource* vtkWin32VideoSource::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkVideoSource.

virtual const char* vtkWin32VideoSource::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkVideoSource.

int vtkWin32VideoSource::IsTypeOf (  const char *    type )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkVideoSource.

virtual int vtkWin32VideoSource::IsA (  const char *    type )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkVideoSource.

vtkWin32VideoSource* vtkWin32VideoSource::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::PrintSelf (  ostream &    os, vtkIndent    indent )  [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::Record (    )  [virtual]

Standard VCR functionality: Record incoming video. Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::Play (    )  [virtual]

Standard VCR functionality: Play recorded video. Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::Stop (    )  [virtual]

Standard VCR functionality: Stop recording or playing. Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::Grab (    )  [virtual]

Grab a single video frame. Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::SetFrameSize (  int    x, int    y, int    z )  [virtual]

Request a particular frame size (set the third value to 1). Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::SetFrameRate (  float    rate )  [virtual]

Request a particular frame rate (default 30 frames per second). Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::SetOutputFormat (  int    format )  [virtual]

Request a particular output format (default: VTK_RGB). Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::SetPreview (  int    p )

Turn on/off the preview (overlay) window.

virtual void vtkWin32VideoSource::PreviewOn (    )  [virtual]

Turn on/off the preview (overlay) window.

virtual void vtkWin32VideoSource::PreviewOff (    )  [virtual]

Turn on/off the preview (overlay) window.

virtual int vtkWin32VideoSource::GetPreview (    )  [virtual]

Turn on/off the preview (overlay) window.

void vtkWin32VideoSource::VideoFormatDialog (    )

Bring up a modal dialog box for video format selection.

void vtkWin32VideoSource::VideoSourceDialog (    )

Bring up a modal dialog box for video input selection.

void vtkWin32VideoSource::Initialize (    )  [virtual]

Initialize the driver (this is called automatically when the first grab is done). Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::ReleaseSystemResources (    )  [virtual]

Free the driver (this is called automatically inside the destructor). Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::InternalGrab (  LPVIDEOHDR    VideoHdrPtr )

For internal use only

void vtkWin32VideoSource::OnParentWndDestroy (    )

For internal use only

void vtkWin32VideoSource::CheckBuffer (    )  [protected]

void vtkWin32VideoSource::UnpackRasterLine (  char *    outptr, char *    inptr, int    start, int    count )  [protected, virtual]

These methods can be overridden in subclasses Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::DoVFWFormatSetup (    )  [protected]

void vtkWin32VideoSource::DoVFWFormatCheck (    )  [protected]
