void DrawGrid	(	bool	doIsoGrid,
		bool	drawDots,
		DPoint3dCR	gridOrigin,
		DVec3dCR	xVector,
		DVec3dCR	yVector,
		UInt32	gridsPerRef,
		Point2dCR	repetitions
	)

Draw the grid matrix.

Parameters

[in]	doIsoGrid	Draw the isometric grid points (if applicable).
[in]	drawDots	Draw grid dots.
[in]	gridOrigin	Point for the origin of the grid matrix.
[in]	xVector	Direction of grid X.
[in]	yVector	Direction of grid y.
[in]	gridsPerRef	Draw reference lines.
[in]	repetitions	X,y values for number or repetitions.

void DrawPointCloud ( IPointCloudDrawParams * drawParams )

Draw a 3D point cloud.

Parameters

[in] drawParams Object containing draw parameters.

void DrawQvElem2d	(	QvElem *	qvElem,
		double	zDepth,
		int	subElemIndex = `0`
	)

Draw a QvElem that was previously creating using ICachedDraw with the supplied display priority value.

void DrawQvElem3d	(	QvElem *	qvElem,
		int	subElemIndex = `0`
	)

Draw a QvElem that was previously creating using ICachedDraw.

void DrawRaster	(	DPoint3d const	points[4],
		int	pitch,
		int	numTexelsX,
		int	numTexelsY,
		int	enableAlpha,
		int	format,
		byte const *	texels,
		DPoint3dCP	range
	)

Draw a raster image in 3d.

void DrawRaster2d	(	DPoint2d const	points[4],
		int	pitch,
		int	numTexelsX,
		int	numTexelsY,
		int	enableAlpha,
		int	format,
		byte const *	texels,
		double	zDepth,
		DPoint2dCP	range
	)

Draw a raster image in 2d.

bool DrawSprite	(	ISprite *	sprite,
		DPoint3dCP	location,
		DPoint3dCP	xVec,
		int	transparency
	)

Draw a sprite at a specific location.

Parameters

[in]	sprite	The sprite definition.
[in]	location	The location where the origin of the sprite should be drawn (in DgnCoordSystem::View coordinates.)
[in]	xVec	A vector that points in the direction (in DgnCoordSystem::View coordinates) that the x vector of the sprite definition should be oriented. This allows for rotating sprites. If NULL, sprite is draw unrotated.
[in]	transparency	Sprite is drawn with this transparency (0=opaque, 255=invisible).

Note: this method is only valid from View Decorators.

void DrawTiledRaster ( ITiledRaster * tiledRaster )

Draw a Tiled Raster.

Parameters

[in] tiledRaster The Tiled Raster to draw.

void PopRenderOverrides ( )

Pop a previous change to the view flags and/or display style.

void PushRenderOverrides	(	ViewFlags	,
		CookedDisplayStyleCP	= `0`
	)

Push a change to the current view flags and/or display style for subsequent draw calls.

void SetSymbology	(	UInt32	lineColorTBGR,
		UInt32	fillColorTBGR,
		int	lineWidth,
		UInt32	linePattern
	)

Set the active symbology for this IViewDraw.

All subsequent draw methods will use the new active symbology.

Parameters

[in]	lineColorTBGR	TBGR line color.
[in]	fillColorTBGR	TBGR color for filled regions.
[in]	lineWidth	The line width in pixels.
[in]	linePattern	The 32 bit on/off pattern for lines.

void SetToViewCoords ( bool yesNo )

Set the coordinate system temporarily to DgnCoordSystem::View.

This removes the root coordinate system, including all camera definitions. It is ONLY valid or useful for drawing "overlay" graphics while drawing View Decorations.

Parameters

[in] yesNo If true, set to DgnCoordSystem::View. If false, restore to DgnCoordSystem::Root.

Note: calls to this method should be paired with true then false values for yesNo.
