Typedef Documentation

◆ TSLUserGeometryLoadCallback

typedef TSLClientUserGeometryEntity *(* TSLUserGeometryLoadCallback) (TSLifstream &stream, int userGeometryID, bool &assumeOwnership)

This function typedef defines the signature for a callback routine that is required to be called to load a user defined Geometry Entity.

Implementation: TSLClientUserGeometryEntity* loadUserGeometryCallback( TSLifstream& stream, int userGeometryID, bool& assumeOwnership );

All registered callbacks will be called, in order, until the one that returns a client for the userGeometryID is found. Implementations must therefore expect a mismatch between the userGeometryID.

Parameters
streamThe input file stream that has had the data copied into.
userGeometryIDA value that uniquely identifies the User Geometry object.
assumeOwnershipThe user should set this value based upon whether the returned callback should become owned by the MapLink created TSLUserGeometryEntity. True indicates ownership is transferred, whilst false implies that the returned object remains owned by the user. This is important if the code calling MapLink was not built using the same compiler version, for instance when using differing versions of Microsoft Visual Studio.
ReturnValue

The callback should return the TSLClientUserGeometryEntity object or NULL.

Enumeration Type Documentation

◆ TSLAreaRelations

enum TSLAreaRelations

Enumerated type describing area relations.

Enumerator
TSLAreaRelationsOutside 
TSLAreaRelationsOnEdge 
TSLAreaRelationsInside 

◆ TSLCoordSetClassificationEnum

enum TSLCoordSetClassificationEnum
Enumerator
TSLCoordSetClassificationSimple 
TSLCoordSetClassificationSelfTouching

enum TSLCoordSetExtendHint

Enumerated type describing the way in which a TSLCoordSet allocates new memory when its capacity is exceeded.

Enumerator
TSLCoordSetExtendDefault 

The default. An unspecified allocation mechanism.

TSLCoordSetExtendByBlockSize 

Each time the capacity is exceeded, the memory is extended in blocks, the size of which you can specify.

TSLCoordSetExtendByDoubling 

Each time the capacity is exceeded, the capacity is doubled.

◆ TSLDimensionUnits

enum TSLDimensionUnits

Enumerated type used to indicate how various sizing and offset parameters should be interpreted. It presently applies to edge thickness, text offsets and text and symbol sizes.

When undefined, the default varies according to application. For example the default for edge thickness is Pixels, whilst the default for text and symbol size is ScaleFactor. This is for compatibility with previous releases of MapLink.

Note:

  1. The ScaleFactor interpretation is only relevant for text and symbol sizing, not for other offsets or thickness parameters.
  2. The Points interpretation only affects line thickness, text size, text offsets and symbol size.
  3. There are 72 points to an inch.
Enumerator
TSLDimensionUnitsMultiple 

Used for Editor queries when multiple selections have different values.

TSLDimensionUnitsUndefined 

The default, varies according to application.

◆ TSLGeodeticInterpolationOptionsEnum

enum TSLGeodeticInterpolationOptionsEnum

Specifies interpolation options for geodetic primitives. These flags are mutually exclusive.

Note that interpolation can be turned on and off independently of these flags, and if interpolation is off, these flags will be ignored.

  • TSLGeodeticInterpolationOptionsGeodesicPathWGS84Accurate: This applies a geodesic path (great circle) to the reference ellipsoid, WGS84.
  • TSLGeodeticInterpolationOptionsGeodesicPathWGS84Spheroid: This applies a geodesic path (great circle) to the reference ellipsoid, WGS84, but ignores the flattening value so is less accurate but slightly faster than the TSLGeodeticInterpolationOptionsGeodesicPathWGS84Accurate option.
  • TSLGeodeticInterpolationOptionsGeodesicPathSphere:This applies a geodesic path (great circle) but treats the Earth as a sphere. This is the least accurate but fastest option.

Deprecated values:

  • TSLGeodeticInterpolationOptionsDefault: default interpolation.
  • TSLGeodeticInterpolationOptionsGreatCircle: use great circles to interpolate instead of the default method.
  • TSLGeodeticInterpolationOptionsSpherical: assume the Earth is a sphere when interpolating (if not present, assume Earth is a spheroid).
Enumerator

All rendering attributes in this enum are of integer type. Some attributes are available on all entities, others are specific to an entity type. Note that some of the attributes listed below are not available for feature-based rendering.

Note that TSLRenderingAttributeReadOnly only applies to rendering attributes such as colours/styles and does not prevent the geometry from being modified.

Available on all entities, but not features:

  • TSLRenderingAttributeReadOnly

Available on all TSLText entities and features:

  • TSLRenderingAttributeTextFixedHeight : Deprecated, use min and max height instead.

◆ TSLRenderingAttributeDouble

enum TSLRenderingAttributeDouble

Rendering attributes for Entities and features. The methods which use this enum use C++ function overloading to provide some measure of type safety. All rendering attributes in this enum are of double type.

Available on TSLText entities and features:

  • TSLRenderingAttributeTextSizeFactor : Units defined by TSLRenderingAttributeTextSizeFactorUnits
  • TSLRenderingAttributeTextOffsetX : Units defined by TSLRenderingAttributeTextOffsetUnits
  • TSLRenderingAttributeTextOffsetY : Units defined by TSLRenderingAttributeTextOffsetUnits

Available on TSLArc and TSLPolyline entities and features:

  • TSLRenderingAttributeEdgeThickness : Units defined by TSLRenderingAttributeEdgeThicknessUnits

Available on TSLPolygon and TSLBorderedPolygon entities and features:

  • TSLRenderingAttributeExteriorEdgeThickness : Units defined by TSLRenderingAttributeExteriorEdgeThicknessUnits

Available on all TSLSymbol entities and features:

  • TSLRenderingAttributeSymbolSizeFactor : Units defined by TSLRenderingAttributeSymbolSizeFactorUnits

Available on TSL3DModel entities and features:

  • TSLRenderingAttributeModelDistanceLOD_1 : Defines the point at which this model is display at (distance from eye in meters).
  • TSLRenderingAttributeModelDistanceLOD_2 : Defines the point at which this model is display at (distance from eye in meters).
  • TSLRenderingAttributeModelDistanceLOD_3 : Defines the point at which this model is display at (distance from eye in meters).
  • TSLRenderingAttributeModelDistanceLOD_4 : Defines the point at which this model is display at (distance from eye in meters).

Available on TSL3DEntity entities and features:

  • TSLRenderingAttributeMinDrawDistance

  • TSLRenderingAttributeMaxDrawDistance

    Defines the range, in meters, between which the entity is drawn.

    Range is defined as: [MinDrawDistance..MaxDrawDistance[

    Negative values mean that the distance is ignored.

    The distance calculated is the distance from the near clip plane in meters to the centre of the Bounding Box for the entity.

    These settings help you structure your drawing objects in such a way to improve the drawing performance by creating 'Levels of Detail', either by using a group structure or via setting particular display ranges on individual entities.

    For example; this works by having a top level group and then at least two groups below this. One group specifies the near drawing range and the other the drawing range for further away, for example: 

    Group0 - [-1, -1[               (contains Group1 and Group 2)
   Group1 -  Range [-1, 10000[  (Nearer Drawing)
   Group2 -  Range [10000, -1[  (Further away Drawing)

Group1 should contain the complex drawing.
Group2 should contain a simpler drawing.

    This approach lends itself to further levels of detail. How many that are required is very dependent upon how complex your display is.

    If a display range is set on a group then the group culling will occur before the contents are checked.
