Detailed Description
A map object: a point, linear object, polygon object, or array (texture).
Member Function Documentation
◆ ContourCount()
|
virtual |
Gets the number of contours in the path.
Implements CartoType::Path.
◆ GetCenter()
Returns the center of a map object in map coordinates.
The center is defined as the center of gravity for polygons and arrays, a point half way along the path for lines, and the point itself for points.
◆ GetCenterInDegrees()
Returns the center of a map object in degrees.
The center is defined as the center of gravity for polygons and arrays, a point half way along the path for lines, and the point itself for points. Because the center is calculated using map coordinates then converted to degrees, it depends on the map projection used by the map object.
◆ GetMatch()
| Result CartoType::MapObject::GetMatch | ( | Match^ | aMatch, |
| String^ | aText, | ||
| StringMatchMethod | aMatchMethod, | ||
| String^ | aAttributes, | ||
| bool | aPhrase | ||
| ) |
Finds the first string attribute matching aText, using aMatchMethod, and returns information about it in aMatch.
If aAttributes is non-null this function examines only attributes in the supplied comma-separated list, otherwise it examines all attributes except those starting with an underscore, which by convention are non-textual. Attribute names may contain the wild cards ? and *. If aPhrase is true, matches of phrases within the attribute are allowed.
◆ GetPoint()
|
virtual |
Gets a point, specifying it by contour index and point index, and places it in aPoint.
Implements CartoType::Path.
◆ PointCount()
|
virtual |
Gets the number of points in a contour.
Implements CartoType::Path.
