XnSceneMetaData * | GetUnderlying () |
Saves the frame object (data and configuration) from the xn::SceneAnalyzer node. This frame object is a snapshot of the generated scene data and its associated configuration information at a certain point in time. This metadata provides fast and easy access to the SceneAnalyzer node's saved frame object.
xn::SceneMetaData::SceneMetaData | ( | ) | [inline] |
XnStatus xn::SceneMetaData::CopyFrom | ( | const SceneMetaData & | other | ) | [inline] |
Performs a deep-copy of another metadata object (including duplication of the data buffer)
[in] | other | source object |
const XnLabel*& xn::SceneMetaData::Data | ( | ) | [inline] |
Returns the scene map.
Remarks
This method returns a pointer to the first scene pixel in the map. The scene map is implemented as a row-major order compact layout of pixels in the map.
The pixel format of the map is XnLabel, i.e. 16-bit integer values, where every user has a distinct label.
This method is reimplemented from the xn::OutputMetaData class.
Reimplemented from xn::OutputMetaData.

XnSceneMetaData* xn::SceneMetaData::GetUnderlying | ( | ) | [inline] |
Gets the C object that is wrapped by this object.
Reimplemented from xn::MapMetaData.
const XnSceneMetaData* xn::SceneMetaData::GetUnderlying | ( | ) | const [inline] |
Gets the C object that is wrapped by this object.
Reimplemented from xn::MapMetaData.

XnUInt32 | nXRes, | |||
XnUInt32 | nYRes, | |||
const XnLabel * | pExternalBuffer | |||
) | [inline] |
Shallow copies another SceneMetaData object, and then ReAdjust it.
[in] | other | source object |
[in] | nXRes | requested number of columns in the map |
[in] | nYRes | requested number of rows in the map |
[in] | pExternalBuffer | Optional. An external buffer matching requested resolution. If NULL, A buffer will be allocated. |
void xn::SceneMetaData::InitFrom | ( | const SceneMetaData & | other | ) | [inline] |
Shallow-Copies an SceneMetaData object.
[in] | other | source object. |
const xn::LabelMap& xn::SceneMetaData::LabelMap | ( | ) | const [inline] |
Gets a light object wrapping the label map
const XnLabel& xn::SceneMetaData::operator() | ( | XnUInt32 | x, | |
XnUInt32 | y | |||
) | const [inline] |
Gets the label of a single pixel of the frame map by its X and Y positions.
[in] | x | X-coordinate of the pixel in the map |
[in] | y | Y-coordinate of the pixel in the map |
Remarks
The values are of type XnLabel. Each pixel's value labels it according to user.
const XnLabel& xn::SceneMetaData::operator[] | ( | XnUInt32 | nIndex | ) | const [inline] |
Gets the label of a single pixel of the frame map by its index in the array.
[in] | nIndex | The index of the pixel in the buffer. |
Remarks
The values are of type XnLabel. Each pixel's value labels it according to user.
XnStatus xn::SceneMetaData::ReAdjust | ( | XnUInt32 | nXRes, | |
XnUInt32 | nYRes, | |||
const XnLabel * | pExternalBuffer = NULL | |||
) | [inline] |
Changes dimensions of the pixel-map.
[in] | nXRes | Number of columns in the map |
[in] | nYRes | Number of rows in the map |
[in] | pExternalBuffer | Optional. An external buffer to be used. If NULL is passed, a buffer will be allocated. |
XnLabel* xn::SceneMetaData::WritableData | ( | ) | [inline] |
Gets a pointer to the writable buffer (see Frame Objects and Metadata Objects).
Reimplemented from xn::OutputMetaData.
xn::LabelMap& xn::SceneMetaData::WritableLabelMap | ( | ) | [inline] |
Gets a light object wrapping the writable label map
