An image that gives an overview of the structure of the GeoObjectsMapLib

Below is a summary of the classes used in the GeoObjectsMapLib.

Class	Use
BMGeoMap	This is the class that defines the main map control.

Bins	A collection of Bin objects.
CoordinateSystem	Used by BMGeoMap and Layer to define their coordinate system.
CustomGeometry	Used to define a custom Feature2 that is drawn based on the SetCustomDrawCallBack function defined by the user.

Feature	Used by the Layer object to define individual items on that layer.
Feature2	Used by the Layer2 object to define individual items on that layer.
Features	A collection of Feature or Feature2 objects used by Layer and Layer2 objects.
GoBrushRendition	Used to define how to fill various objects.
GoFontRendition	Used to define how an objects text will look.
GoPenRendition	Used to define how the lines for an object will be drawn.
Image	Used by BMGeoMap to define a specialty layer that displays an image. (These layers will be displayed under all others)
Image2	An extension of the Image object containing additional properties.
Images	A collection of Image objects used by BMGeoMap.
Layer	Used by BMGeoMap to define a vector file.
Layer2	Used by BMGeoMap for the user to draw to.
Layer3	An extension of the Layer object containing additional properties.
LayerProperties	Used by BMGeoMap when calling AddLayer in order to load the layer with all the correct properties.
Layers	A collection of Layer objects used by BMGeoMap.
LegendIcon	Used to create bmp files of GoBrushRendition, GoFontRendition, and GoPenRendition to be displayed in a legend.
LineGeometry	Used to define Feature2 objects that are lines.
MapGrid	Used by BMGeoMap to setup and display a grid on the map.
MapProjection	Used to define CoordinateSystem objects' projection.
MapProperties	Used by BMGeoMap to store and set it's properties.
OleMinMax	Used for specifying a range of values.
OlePoint	Used to represent a point on the x/y plane.
OleRectangle	Used to represent a bounding rectangle.
PickedFeatures	A collection of Feature or Feature2 objects currently picked.
PointGeometry	Used to define Feature2 objects that are points.
PolygonGeometry	Used to define Feature2 objects that are polygons.
RectangleGeometry	Used to define Feature2 objects that are rectangles.
SymbolGeometry	Used to define Feature2 objects that are symbols.
TextGeometry	Used to define Feature2 objects that are text.

Below is a summary of the enumerations used in the GeoObjectsMapLib.

Enumeration	Use
AngleUnitConstants	Used to specify the type of angular units being used.
BinAlgorithmConstants	Used by BMGeoMap to decide which binning algorithm is used.
BrushStyleConstants	Used by GoBrushRendition to decide which brush style to use.
ChangeEventConstants	Used to determine which event(s) occurred on a Change event of BMGeoMap.
ColorAlgorithmConstants	Used to identify the color scheme to use when generating colors for the bins.
CoordinateConversionConstants	Used to determine the source points coordinate system along with the destination coordinate system when using BMGeoMap's ConvertCoordinate method.
DataFieldTypeConstants	Used to identify a value that indicates the type of the user data read.
DatumShiftTypeConstants	Used by the Datum object to identify the type of datum shift.
EllipsoidDefinitionConstants	Used to identify which ellipsoid is being used. These values correspond to MapInfo's values for ellipsoids.
GeometryClassConstants	Used to identify if a Layer has features of only one class type.
GeometryTypeConstants	Used to identify the type of geometry of a Feature or Feature2 object (Arc, Custom, Ellipse, etc...).

MapGridEdgeLabelConstants	Used by MapGrid to decide which edges to put the grid labels on.
MapGridStyleConstants	Used by MapGrid to decide the style of the grid markings.
MapProjectionConstants	Used to identify which projection is being used. These values correspond to MapInfo's values for projections.
PenStyleConstants	Used by GoPenRendition to decide which line style will be used.
PointStyleConstants	Used by PointGeometry to decide they style of the point marker.
PrintViewConstants	Used by BMGeoMap's PrintView method to determine what to print.
ScaleModeConstants	Used to decide what format the scale is in.
TextEffectConstants	Used by GoFontRendition to decide which text effects to use.
