|
Advance the buffer by one frame or n frames. |
|
Set whether to automatically advance the buffer before each grab. Default: on |
|
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 vtkImageSource. Reimplemented in vtkMILVideoSource. |
|
Get a time stamp in seconds (resolution of milliseconds) for a video frame. Time began on Jan 1, 1970. |
|
Are we in continuous grab mode? |
|
Grab a single frame or multiple frames. Reimplemented in vtkMILVideoSource. |
|
Initialize the hardware. This is called automatically on the first Update or Grab. Reimplemented in vtkMILVideoSource. |
|
The internal function which actually does the grab. You will definitely want to override this if you develop a vtkVideoSource subclass. Reimplemented in vtkMILVideoSource. |
|
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 vtkImageSource. Reimplemented in vtkMILVideoSource. |
|
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 vtkImageSource. Reimplemented in vtkMILVideoSource. |
|
Instantiate object with no start, end, or progress methods. Reimplemented from vtkImageSource. Reimplemented in vtkMILVideoSource. |
|
Go into continuous grab mode. The video source will be automatically Modified() every time a new frame arrives. Reimplemented in vtkMILVideoSource. |
|
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 vtkSource. Reimplemented in vtkMILVideoSource. |
|
Release the video driver. This is called automatically when the vtkVideoSource is destroyed. Reimplemented in vtkMILVideoSource. |
|
Rewind the buffer by one frame or n frames. |
|
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 vtkImageSource. Reimplemented in vtkMILVideoSource. |
|
Set the clip rectangle for the frames. The video will be clipped before it is copied into the framebuffer. Changing the ClipRegion will destroy the current contents of the framebuffer. The default ClipRegion is (0,VTK_INT_MAX,0,VTK_INT_MAX,0,VTK_INT_MAX). |
|
Set/Get the coordinates of the lower, left corner of the frame. Default: (0.0,0.0,0.0) |
|
Set/Get the pixel spacing. Default: (1.0,1.0,1.0) |
|
Set size of the frame buffer, i.e. the number of frames to store. |
|
Set the frame rate for 'Play' mode. The default is 30 frames/s for most video digitizers. Reimplemented in vtkWin32VideoSource. |
|
Set the full-frame size. This must be an allowed size for the device, the device may either refuse a request for an illegal frame size or automatically choose a new frame size. The default is usually 320x240x1, but can be device specific. The 'depth' should always be 1 (unless you have a device that can handle 3D acquisition). |
|
Set this flag to automatically do a grab on each Update. This might be less CPU-intensive than Play() for doing screen animations. |
|
Set the number of frames to copy to the output on each execute. The frames will be concatenated along the Z dimension, with the most recent frame first. Default: 1 |
|
For RGBA output only (4 scalar components), set the opacity. This will not modify the contents of the framebuffer, only subsequently grabbed frames. |
|
Set the output format. This must be appropriate for device, usually only VTK_LUMINANCE, VTK_RGB, and VTK_RGBA are supported. Reimplemented in vtkMILVideoSource. |
|
Get/Set the WholeExtent of the output. This can be used to either clip or pad the video frame. This clipping/padding is done when the frame is copied to the output, and does not change the contents of the framebuffer. This is useful e.g. for expanding the output size to a power of two for texture mapping. The default is (0,-1,0,-1,0,-1) which causes the entire frame to be copied to the output. |
|
Enable a video preview window if supported by driver. |
|
End continuous grab mode. Reimplemented in vtkMILVideoSource. |
|
These methods can be overridden in subclasses |
|
This method returns the largest data that can be generated. Reimplemented from vtkSource. |
