Create a copy of style using the deep clone process.

The difference between deep clone and shallow clone is as follows: In shallow cloning, only the object is copied; the objects within it are not. By contrast, deep cloning copies the cloned object as well as all the objects within.

This method draws the features on the canvas you provided.

This method is the concrete wrapper for the abstract method DrawCore. In this method, we take the features you passed in and draw them on the canvas you provided. Each style (based on its properties) may draw each feature differently.

As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.

This method returns the column data for each feature that is required for the style to properly draw.

This method is the concrete wrapper for the abstract method GetRequiredColumnNamesCore. In this method, we return the column names that are required for the style to draw the feature properly. For example, if you have a style that colors areas blue when a certain column value is over 100, then you need to be sure you include that column name. This will ensure that the column data is returned to you in the feature when it is ready to draw.

In many of the styles, we add properties to allow the user to specify which field they need; then, in the GetRequiredColumnNamesCore we read that property and add it to the collection.

This method will determine whether the label will be suppressed because it is a duplicate.

This method is the concrete wrapper for the abstract method CheckDuplicateCore. This method will determine if the label will be suppressed because it is a duplicate. It also takes into consideration the duplicate rules for the class. So, for example, if we set to allow duplicates, then the method will always return false. If the class is set to not allow duplicates and this label is a duplicate, then it will return true and be suppressed.

This method will determine if the label will be suppressed because it is a duplicate.

This overridden method is called from the concrete public method CheckDuplicate. This method will determine if the label will be suppressed because it is a duplicate. It also takes into consideration the duplicate rules for the class. So, for example, if we set to allow duplicates, then the method will always return false. If the class is set to not allow duplicates and this label is a duplicate, then it will return true and be suppressed.

This method will determine if the label will be suppressed because of overlapping.

This method is the concrete wrapper for the abstract method CheckOverlappingCore. This method will determine if the label will be suppressed because it is overlapping another label. It also takes into consideration the overlapping rules for the class. So, for example, if we set to allow overlap, then the method will always return false. If the class is set to not allow overlap and this label is overlapping, then it will return true and be suppressed.

This property gets the advanced properties of the class.

The advanced properties have been consolidated in the Advanced property. This way, the standard options are more easily visible and the advanced options are hidden away.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

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

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.

<!– ThinkGeo.MapSuite.Core.PositionStyle –> Go Back

This property gets and sets whether the labeler will attempt to change the label position to avoid overlapping for point-based features.

The positioning of point labels is mainly determined by the PointPlacement property. This allows you place the text to the right, top, bottom, etc. of the point. In some cases, placing the text in a certain place will cause many labels to be suppressed when the points are dense. This property allows you to override the PointPlacement property and allow the labeler to try other locations, if the default location would cause the label to be suppressed.

<!– ThinkGeo.MapSuite.Core.PositionStyle –> Go Back

This property returns a collection of area styles allowing you to stack multiple area styles on top of each other.

Using this collection, you can stack multiple area styles on top of each other. When we draw the features, we will draw them in order that they exist in the collection. You can use these stacks to create drop shadow effects, multiple colored outlines, etc.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

This property gets and sets the format that will be applied to the text which can be parsed to DateTime type.

With this property, you can apply formats to the text that is retrieved from the feature.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

Gets or sets the DrawingLavel for this style.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

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

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.

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

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.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

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.

<!– ThinkGeo.MapSuite.Core.PositionStyle –> Go Back

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

<!– ThinkGeo.MapSuite.Core.PositionStyle –> Go Back

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

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.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

This property gets and sets the font that will be used to draw the text.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

This property gets and sets whether we should force horizontal labeling for lines.

Normally, lines are labeled in the direction of the line. There may be some cases, however, when you want to have the line labeled horizontally regardless of the line's direction. In such a case, you can set this property to force the lines to be labeled horizontally.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

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

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.

<!– ThinkGeo.MapSuite.Core.PositionStyle –> Go Back

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

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.

<!– ThinkGeo.MapSuite.Core.PositionStyle –> Go Back

This property gets and sets the halo pen you may use to draw a halo around the text.

The halo pen allows you to draw a halo effect around the text, making it stand out more on a busy background.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

This property gets and sets the filename and path for the image you want to use in the style.

You can also optionally use the IconImage property if the image you want to use is derived from a stream.

<!– ThinkGeo.MapSuite.Core.IconStyle –> Go Back

This property gets and sets the GeoImage you want to use for the image.

You will typically want to use this property if your image is derived from a stream. Otherwise, you can use the IconFilePathName property to specify where the icon is located and we will handle the rest.

<!– ThinkGeo.MapSuite.Core.IconStyle –> Go Back

This property gets and sets the scale of the image you want to draw.

This property allows you to scale the image up and down depending on how large or small you want it. It can be changed dynamically, so you could change it at every scale level to resize the bitmap based on the current scale. A scale of 1 would be the original size, while a scale of 2 would double the size. A scale of .5 would reduce the size of the image by half, and so on.

<!– ThinkGeo.MapSuite.Core.IconStyle –> Go Back

This property gets and sets the active status of the style.

If the style is not active then it will not draw.

<!– ThinkGeo.MapSuite.Core.IconTextStyle –> Go Back

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

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

<!– ThinkGeo.MapSuite.Core.PositionStyle –> Go Back

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

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.

<!– ThinkGeo.MapSuite.Core.PositionStyle –> Go Back

Gets a value represents a keyValuepair which is a feature id and label position of the feature

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

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

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.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

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

This determines how much larger the mask is than the text, in pixels.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

This property gets and set the name of the style.

This name is not used by the system; it is only for the developer. However, it can be used if you generate your own legend.

<!– ThinkGeo.MapSuite.Core.Style –> Go Back

This property gets and sets the format that will be applied to the text which can be parsed to double type.

With this property, you can apply formats to the text that is retrieved from the feature.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

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

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.

<!– ThinkGeo.MapSuite.Core.PositionStyle –> Go Back

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

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.

<!– ThinkGeo.MapSuite.Core.PositionStyle –> Go Back

This property gets and sets the mode that determines how to locate polygon's labeling

There are two ways to handle polygon's labeling location. The first is to use polygon's centroid as the labeling location, the second way is to use polygon's boungdingbox center as the labeling location.

<!– ThinkGeo.MapSuite.Core.PositionStyle –> Go Back

This property gets the collection of fields that are required for the style.

This property gets the collection of fields that are required for the style. These are in addition to any other columns you specify in styles that inherit from this one. For example, if you have use a ValueStyle and it requires a column name for the value comparison, then that column does not need to be in this collection. You only use the RequiredColumnNames for columns you need beyond those required by specific inherited styles.

<!– ThinkGeo.MapSuite.Core.Style –> Go Back

This property gets and sets the rotation angle of the item being positioned.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

Gets or sets the SplineType for labeling.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

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

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.

<!– ThinkGeo.MapSuite.Core.IconStyle –> Go Back

This property gets and sets the column name in the data that you want to get the text from.

This property is used when retrieving text from a feature. You will want to specify the name of the column that contains the text you want to draw.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

This property gets and sets the format that will be applied to the text.

With this property, you can apply formats to the text that is retrieved from the feature.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

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

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.

<!– ThinkGeo.MapSuite.Core.PositionStyle –> Go Back

This property gets and sets the SolidBrush that will be used to draw the text.

You can use this property to draw a solid color; however, if you need to use other brushes, you can access them through the Advanced property of this class.

<!– ThinkGeo.MapSuite.Core.TextStyle –> Go Back

This property gets and sets the X pixel offset for drawing each feature.

This property allows you to specify an X offset. When combined with a Y offset, it is useful to allow you to achieve effects such as drop shadows, etc. There also may be times when you need to modify the location of feature data so as to better align it with raster satellite data.
