TPG.GeoFramework.Contracts.IViewport Interface Reference

Inheritance diagram for TPG.GeoFramework.Contracts.IViewport:

Public Member Functions
bool	Inside (IViewport outer, double tolerance=0.0)
bool	Intersects (IViewport vp)
Public Member Functions inherited from TPG.GeoFramework.Contracts.IRasterProjector
GeoPos[]	GetCorners ()
	Returns an array of geographic positions of raster corners,.
Vector	GetNorthVector (GeoPos pos)
	Returns a vector in pixel coordinates pointing north at geopos, with a length of 1m.
Vector	GetEastVector (GeoPos pos)
	Returns a vector in pixel coordinates pointing east at geopos, with a length of 1m.
Vector	GetPixelSize (GeoPos pos)
	Returns pixel size in meters at geopos, separate X & Y sizes. Note: PixelSize().Length is NOT the pixel size,.
bool	Contains (GeoPos pos)
	Returns true if pos is inside rectangle (0,0,Width,Height)
bool	Intersects (IRasterProjector rp)
	Check if this raster projector intersects another raster projector.
GeoPos[]	GetRefinedBoundary (int subdivisions)
	Calculate a set of geographical points along the border of the raster projector. This set will include the corners, as well as a number of points along each edge, corresponding to the subdivisions parameter. If subdivisions is 1, only the corners are returned.
GeoRect	CalcGeoRect ()
	Calculate geographical bounds. This method will calculate the geographical bounds of the raster projector by checking the corners and midpoints. This will account for projections with some curvature, but if you need even higher precision, you may have to do this with more sample points.
Public Member Functions inherited from TPG.GeoFramework.Contracts.IProjector
bool	LatLonToXY (GeoPos latlon, out Point xy)
	Convert from geographical lat/lon coordinate to pixel coordinates.
bool	LatLonToXY (GeoPos[] latlon, out Point[] xy)
	Convert multiple points from geographical lat/lon coordinates to pixel coordinates.
bool	XYToLatLon (Point xy, out GeoPos latlon)
	Convert from pixel coordinate to geographical lat/lon.
bool	XYToLatLon (Point[] xy, out GeoPos[] latlon)
	Convert multiple points from pixel coordinates to geographical lat/lon.

Matrix3x3	ImageToProj [get]
	Transformation matrix for converting from pixel coordinates to projected coordinates.
IProjector	GeoProjector [get]
	Projector between geographical and projected coordinates. The complete raster projection is this projector combined with the raster projection matrix.

String	ProjectionString [get]
	Get projection ID for the current projection.
DistanceUnit	Unit [get]
	Nominal unit in the XY plane.
double	UnitScale [get]
	XY unit scale factor. Used with IProjectors of type GeoTransform. XY values may be multiplied by this factor to produce values corresponding to given DistanceUnit.
bool	IsProjection [get]
	True if the IProjector transform contains a projection component, false if the transform is 'only' a datum converion.
