All Known Implementing Classes:

GeometryDraw

public interface IGeometryDraw
extends Serializable

Provides access to members that convert a geometry into a sequence of Win32 drawing instructions.

Description

The GeometryDraw coclass is used to draw an IGeometry object to an IDisplay object.

The GeometryDraw object provides an alternative to using the ISymbol::Draw method, which draws a Symbol to a device context using a particular Geometry to provide the location.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Method Summary

void	draw(int hDC, IGeometry pGeometry, ITransformation pTransformation, IEnvelope pVisibleBounds) Draws the geometry.
void	queryGeometryFromWin32Path(int hDC, ITransformation transform, IPolygon geometry) Queries the geometry.

Method Detail
