Member Function Documentation

const DISPPARM& GRE_LAYER_SURFACE::GetDispParm (   )  const [inline]

Retrieve layer-specific display parameters. Definition at line 122 of file lrsurface.h.

ERRVALUE GRE_LAYER_SURFACE::GetPointsZ (  const TRANS2D_MAPGEN &  PtoS, POLYLINE &  PolyLine, double  dftz )

Get Z coordinates for set of points. This method is used mainly in 3D rendering and measurement to obtain the Z coordinates of one or more points in some other map projection or layer coordinate system. Parameters: PtoS  Transformation from point to surface object coordinates PolyLine  Points to obtain Z values for dftz  Default Z value for off-surface points

int GRE_LAYER_SURFACE::GetPointsZ (  const TRANS2D_MAPGEN &  PtoS, DPOINT3D *  points, INT32  NumPoints, double  dftz )  [inline]

Parameters: PtoS  Transformation from point to surface object coordinates points  Points to obtain Z values for NumPoints  Number of points dftz  Default Z value for off-surface points Definition at line 135 of file lrsurface.h.

int GRE_LAYER_SURFACE::GetPointsZ (  const TRANSPARM &  PtoS, DPOINT3D *  points, INT32  NumPoints, double  dftz )

Get Z coordinates for set of points. This method is used mainly in 3D rendering and measurement to obtain the Z coordinates of one or more points in some other map projection or layer coordinate system. Parameters: PtoS  Transformation from point to surface object coordinates points  Points to obtain Z values for NumPoints  Number of points dftz  Default Z value for off-surface points

GRE::TERRAIN* GRE_LAYER_SURFACE::GetTerrain (   )  [inline]

Definition at line 162 of file lrsurface.h.

virtual int GRE_LAYER_SURFACE::OpenObject (  UINT32  filemode = RVCFILE_ReadLock, MDLGPARENT  dlgparent = 0 )  [virtual]

Open object(s) for this layer. Returns: TRUE if was opened, FALSE if open already, < 0 if error Parameters: filemode  RVC file access mode dlgparent  Parent for dialog Reimplemented from GRE_LAYER.

void GRE_LAYER_SURFACE::RegisterType (   )  [static]

Register this layer type.

ERRVALUE GRE_LAYER_SURFACE::SetDispParm (  const DISPPARM &  dispparm  )

Set layer-specific display parameters. This is the recommended method for changing how an existing layer is to be rendered. Validation will be performed on the specified parameters and adjustments made to the layer's copy if necessary. Use of this method usually results in a ChangeBegin / ChangeEnd message pair, and will also generate a ChangeObject message if the spatial object used in the layer is changed. Parameters: dispparm  Parameters to set
