Inheritance diagram for TPG.GeoFramework.Contracts.Geo.Context.IGeoContext:

Public Member Functions
void	CalcTrackingViewport ()
	Calculate viewort from current tracking (panning) data. This should be done right before rendering, and not on every mouse move.

void	LockCurrentResolution ()
	Lock the current screen viewport resolution. This method will cause the map renderer to use the same resolution for all zoom levels, until you call UnlockResolution again. Please note that this will cause severe performance problems when zooming out, and severe rendering artifacts when zooming in.

void	UnlockResolution ()
	Unlock the screen viewport resolution. See LockCurrentResolution().

bool	IsLockedResolution ()
	Returns true if the screen resolution is locked to a specific value.

bool	AreSimilar (IViewport a, IViewport b, int pixelOffsetTolerance)

IViewport	CheckedVp (IViewport vp)

void	Refresh (bool force=false)

Member Function Documentation

◆ CalcTrackingViewport()

void TPG.GeoFramework.Contracts.Geo.Context.IGeoContext.CalcTrackingViewport ( )

Calculate viewort from current tracking (panning) data. This should be done right before rendering, and not on every mouse move.

Implemented in TPG.GeoFramework.Core.GeoContext.

◆ IsLockedResolution()

bool TPG.GeoFramework.Contracts.Geo.Context.IGeoContext.IsLockedResolution ( )

Returns true if the screen resolution is locked to a specific value.

Returns

Implemented in TPG.GeoFramework.Core.GeoContext.

◆ LockCurrentResolution()

void TPG.GeoFramework.Contracts.Geo.Context.IGeoContext.LockCurrentResolution ( )

Lock the current screen viewport resolution. This method will cause the map renderer to use the same resolution for all zoom levels, until you call UnlockResolution again. Please note that this will cause severe performance problems when zooming out, and severe rendering artifacts when zooming in.

Implemented in TPG.GeoFramework.Core.GeoContext.

◆ UnlockResolution()

void TPG.GeoFramework.Contracts.Geo.Context.IGeoContext.UnlockResolution ( )

Unlock the screen viewport resolution. See LockCurrentResolution().

Implemented in TPG.GeoFramework.Core.GeoContext.
