Inheritance diagram for TPG.GeoFramework.Contracts.Geo.Layer.IExportableLayer:

Public Member Functions
void	PreExport ()
	Called before actual export is performed. The layer must ensure that state that changes the appearance of the layer is not altered.

void	Export (Canvas canvas, IGeoContext geoContext, double targetDpi)
	The actual export function. Implementing classes should draw their content using the provided canvas and geo context.

void	PostExport ()
	Called after export is performed. After this no more export functions will be called and the layer should go back to normal operation.

Public Member Functions inherited from TPG.GeoFramework.Contracts.Geo.Layer.IGeoLayerViewModel
void	HandleInputEvent (GeoInputEventArgs inputEventArgs)
	Called to forward events to the layer.

void	Generate ()
	Requests that the layer generates it's view.

void	Update ()
	Event called at regular intervals to update contents of the layer.

void	SetDirty (bool isDirty)
	Sets a boolean value indicating the need for an update of the contents of a layer.

void	SetDirty (object dirtySource)
	Sets dirty flag and stores sender, use to avoid cyclic dirtying.

bool	IsDirty ()

Member Function Documentation

void TPG.GeoFramework.Contracts.Geo.Layer.IExportableLayer.Export	(	Canvas	canvas,
		IGeoContext	geoContext,
		double	targetDpi
	)

The actual export function. Implementing classes should draw their content using the provided canvas and geo context.

Parameters

canvas	The canvas to draw into.
geoContext	The geo context relevant for this export.
targetDpi	The wanted dpi for the export.

void TPG.GeoFramework.Contracts.Geo.Layer.IExportableLayer.PostExport ( )
