Detailed Description

Represents a set of visualization options for shapefile layer.

The set of options is represented by instance of ShapeDrawingOptions class which can be accessed by ShapefileCategory.DrawingOptions, while ShapefileCategory.Expression is used for mapping this options to particular shapes.

Here is a diagram for the ShapefileCategory class.

Property Documentation

DrawingOptions

ShapeDrawingOptions ShapefileCategory.DrawingOptions

getset

Gets or sets visualization options associated with the category.

Examples

LinePattern.cs, PointIcons.cs, and SelectByDistance.cs.

Expression

string ShapefileCategory.Expression

getset

Gets or sets expression which defines shapes which belong to the category.

Examples

MinimalDistance.cs, PointIcons.cs, and SelectByDistance.cs.

MaxValue

object ShapefileCategory.MaxValue

getset

Gets or sets maximum value of the value range the category covers.

The value is used when cvRange is set as ShapefileCategory.ValueType.

New API 4.9.3:

Added in version 4.9.3

MinValue

object ShapefileCategory.MinValue

getset

Gets or sets minimum value of the value range the category covers.

The value is used when either cvSingleValue, cvRange is set for ShapefileCategory.ValueType.

New API 4.9.3:

Added in version 4.9.3

Name

string ShapefileCategory.Name

getset

Gets or sets the name of the category. The names must not be unique.

Examples

SplitByAttribute.cs.

ValueType

tkCategoryValue ShapefileCategory.ValueType

getset

Gets or sets value type for the category.

Depending on value type either ShapefileCategory.MinValue/ShapefileCategory.MaxValue properties or ShapefileCategory.Expression are used in the calculation process. ShapefileCategories.Generate method will set cvSingleValue for unique values classification and ctRange for any interval classification. These values are faster to apply. However manual setting of ShapefileCategory.Expression property will change it to cvExpression.
