TextStyle &para;

        This property gets whether the labeler will try to fit the label as best as it can on
        the visible part of a line on the screen.

Remarks:

A label will normally be displayed in the center of a line. If only a small piece of the line is visible on the screen, we cannot see it's label by default. If we set this property to ture though, the label will be displayed in the center of that piece in screen.

        This property gets whether the labeler will try to fit the label as best as it can on
        the visible part of a polygon on the screen.

Remarks:

A label will normally be displayed in the center of a polygon. If only a small piece of the polygon is visible on the screen, we cannot see it's label by default. If we set this property to ture though, the label will be displayed in the center of that piece in screen.

Property Value¶

AreaStyle
This property gets the AreaStyle used to draw a mask behind the text.

Remarks:

A mask is a plate behind the text that is rectangular and slightly larger than the width and height of the text. It allows the label to stand out well on a busy background. You can also try the HaloPen property instead of the mask, if the mask effect is too pronounced.

MaskMargin¶

This property gets and sets the margin around the text that will be used for the mask.

public DrawingMargin MaskMargin { get; set; }

Property Value¶

GridSize¶

This property gets and sets the grid size used for deterministic labeling.

public int GridSize { get; set; }

Property Value¶

Int32
This property gets the grid sized used for deterministic labeling.

Remarks:

The grid size determines how many labels will be considered as candidates for drawing. The smaller the grid size, the higher the density of candidates. Making the grid size too small may have a performance impact.

DuplicateRule¶

This property gets and sets the rule that determines how duplicate labels are handled.

public LabelDuplicateRule DuplicateRule { get; set; }

Property Value¶

LabelDuplicateRule

        This property gets the rule that determines how duplicate labels are
        handled.

Remarks:

There are three ways to handle duplicate label names. The first is to suppress all duplicates, which means if there are two street segments with the same name then only one will be drawn. The second way is to suppress duplicate labels only if they are in one quarter of the screen. In this way, the screen will be divided into four quadrants, and if the two duplicate labels are in different quadrants, then they will both draw. The last way is to draw all duplicates.

OverlappingRule¶

This property gets and sets the rule that determines how overlapping labels are handled.

public LabelOverlappingRule OverlappingRule { get; set; }

Property Value¶

LabelOverlappingRule
This property gets the rule that determines overlapping labels are handled.

Remarks:

This defines the rules for label overlapping. Currently, either we allow overlapping or we do not. In the future, we may extend this to allow some percentage of partial overlapping.

AllowLabelNudging¶

public bool AllowLabelNudging { get; set; }

Property Value¶

AllowLineCarriage¶

This property gets and sets whether the labeler will allow carriage returns to be inserted.

public bool AllowLineCarriage { get; set; }

Property Value¶

        This property gets whether the labeler will allow carriage returns to be
        inserted.

Remarks:

This property enables the labeler to split long labels into multiple lines if need be. For instance, if you have a lake whose name is "Southern Homestead Lake," then the labeler may try and break the name onto multiple lines in order to better label the feature.

SuppressPartialLabels¶

This property gets and sets whether a partial label in the current extent will be drawn or not.

public bool SuppressPartialLabels { get; set; }

Property Value¶

Remarks:

This property provides a solution to the "cut off" label issue in Map Suite Web Edition and Desktop Edition, which occurs when multiple tiles exist. When you set this property to true, any labels outside of the current extent will not be drawn.

ForceLineCarriage¶

This property gets and sets whether the labeler will force carriage returns to be inserted.

public bool ForceLineCarriage { get; set; }

Property Value¶

        This property gets whether the labeler will force carriage returns to be
        inserted.

Remarks:

This property forces the labeler to split long labels into multiple lines. For instance, if you have a lake whose name is "Southern Homestead Lake," then the labeler will break the name onto multiple lines in order to better label the feature.

FittingPolygon¶

This property gets and sets whether the labeler will try to fit the label as best as it can within the boundary of a polygon.

public bool FittingPolygon { get; set; }

Property Value¶

        This property gets whether the labeler will try to fit the label as best as
        it can within the boundary of a polygon.

Remarks:

None

LabelAllPolygonParts¶

This property gets and sets whether the labeler will label every part of a multi-part polygon.

public bool LabelAllPolygonParts { get; set; }

Property Value¶

        This property gets whether the labeler will label every part of a multi-part
        polygon.

Remarks:

In some cases, you may want to label all of the parts of a multi-part polygon, while in other cases you may not. For example, you may have a series of lakes where you do want to label each polygon. In another case, you may have a country with many small islands and in this case you only want to label the largest polygon.

LabelAllLineParts¶

This property gets and sets whether the labeler will label every part of a multi-part line.

public bool LabelAllLineParts { get; set; }

Property Value¶

        This property gets whether the labeler will label every part of a multi-part
        line.

Remarks:

In some cases, you may want to label all of the parts of a multi-part line, while in other cases you may not.

FittingPolygonFactor¶

This property gets and sets the factor to which it will keep the label inside of the polygon.

public double FittingPolygonFactor { get; set; }

Property Value¶

        This property gets the factor to which it will keep the label inside of the
        polygon.

Remarks:

None

TextLineSegmentRatio¶

This property gets and sets the ratio required for the label length to match the line length.

public double TextLineSegmentRatio { get; set; }

Property Value¶

        This property gets the ratio required for the label length to match the line
        length.

Remarks:

This allows you to suppress labels where the label length would greatly exceed the line length. For example, if you set the ratio to 1, then the label will be suppressed if it is longer than the line. If the ratio is lower, then the label would need to be shorter than the line. If higher, then the label is allowed to run past the length of the line. This allows you to control the look of things like road labeling.

TextPlacement¶

This property gets and sets the location of the label for point features relative to the point.

public TextPlacement TextPlacement { get; set; }

Property Value¶

TextPlacement

        This property gets the location of the label for point features relative to the
        point.

Remarks:

This property allows you to choose where the labels are created relative to the point. For example, you can set the property to RightCenter, which would ensure that all labels are placed to the right of and vertically centered with the point. Different kinds of point layers can be positioned differently. If the point layer is dense and position is not a main concern, then you can try the BestPlacement property. That property overrides this property and tries to fit the label in the best location so that the minimum number of labels are suppressed due to overlapping issues.

MaskType¶

public MaskType MaskType { get; set; }

Property Value¶

MaskType

TextContent¶

This property gives you the option to customize the labeling by using one or more columns. For example supposing I have 2 columns "ColumnA" and "ColumnB" with the values of "ValueA" and "ValueB", by setting this property to "{ColumnA} - {ColumnB}", it will draw "ValueA - ValueB" for the corresponding feature. Do remember to add the columns you want to draw (ColumnA and ColumnB in the case above) to RequiredColumnNames collection;

public string TextContent { get; set; }

Property Value¶

String

MaxAdjacentCharDeltaAngle¶

public double MaxAdjacentCharDeltaAngle { get; set; }

Property Value¶
