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::Initialize (    )  [virtual]

See vtkVideoSource Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::ReleaseSystemResources (    )  [virtual]

Release the video driver. This is called automatically when the vtkVideoSource is destroyed. Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::Grab (  int    n )  [virtual]

Grab a single frame or multiple frames. Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::Grab (    )  [inline]

Reimplemented from vtkVideoSource. Definition at line 73 of file vtkWin32VideoSource.h.

void vtkWin32VideoSource::Play (    )  [virtual]

Go into continuous grab mode. The video source will be automatically Modified() every time a new frame arrives. Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::Stop (    )  [virtual]

End continuous grab mode. Reimplemented from vtkVideoSource.

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

Reimplemented from vtkVideoSource.

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

Set the frame rate for 'Play' mode. The default is 30 frames/s for most video digitizers. Reimplemented from vtkVideoSource.

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

Set the output format. This must be appropriate for device, usually only VTK_LUMINANCE, VTK_RGB, and VTK_RGBA are supported. Reimplemented from vtkVideoSource.

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::InternalGrab (  LPVIDEOHDR    VideoHdrPtr )

For internal use only

void vtkWin32VideoSource::operator= (  const vtkWin32VideoSource &    )  [inline, protected]

Definition at line 96 of file vtkWin32VideoSource.h.

void vtkWin32VideoSource::CheckBuffer (    )  [protected]

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

Reimplemented from vtkVideoSource.

void vtkWin32VideoSource::DoVFWFormatSetup (    )  [protected]

void vtkWin32VideoSource::DoVFWFormatCheck (    )  [protected]
