Member Function Documentation

const DISPPARM& GRE::LAYER_SURFACE::GetDispParm

(

)

const [inline]

Retrieve layer-specific display parameters.

Definition at line 126 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 139 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

(

)

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.

static 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
