ThinkGeo.MapSuite.WindowsPhoneCore.LineStyle
Note: The page was created before Map Suite 10. Map Suite 10.0 organized many classes into new namespaces and assemblies as well as had a few minor breaks in compatibility. The majority of previously built code should work without modification assuming the new namespaces are added. For guidance on upgrading your existing code, please check out MapSuite 10 Upgrade Guide.
<!– Class –> This class is the style used to draw lines.
Remarks
This class is commonly used to draw lines on the GeoCanvas. It is specialized for drawing roads, as this is the main kind of line feature that is most often drawn. You can set an inner, outer and center pen to give you a nice effect. The outer pen draws first, and should typically be black and larger then the inner pen. The inner pen draws next, and should be set as the color of the road you want. It should be thinner than the outer pen. The center pen draws last, and is used to represent a centerline in the road. We suggest that you only use the center pen for highways at low zoom level, as the dashed pen has some performance penalties.

Public Methods
Draw(IEnumerable<Feature>, GeoCanvas, Collection<SimpleCandidate>, Collection<SimpleCandidate>)
This method draws the features on the canvas you provided.
Remarks
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.

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

Protected Methods
DrawCore(IEnumerable<Feature>, GeoCanvas, Collection<SimpleCandidate>, Collection<SimpleCandidate>)
This method draws the features on the canvas you provided.
Remarks
This overridden method is called from the concrete public method Draw. 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.
When overriding this method, consider each feature and its column data values. You can use the full power of the GeoCanvas to do the drawing. If you need column data for a feature, be sure to override the GetRequiredColumnNamesCore and add the columns you need to the collection. 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.

GetRequiredColumnNamesCore()
This method returns the column data for each feature that is required for the style to properly draw.
Remarks
This abstract method is called from the concrete public method GetRequiredFieldNames. 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.

Public Properties
CenterPen
This property gets and sets the center pen for the line.
Remarks
You can set an inner, outer and center pen to give you a nice effect. The outer pen draws first, and should typically be black and larger then the inner pen. The inner pen draws next, and should be set as the color of the road you want. It should be thinner than the outer pen. The center pen draws last, and is used to represent a centerline in the road. We suggest that you only use the center pen for highways at low zoom level, as the dashed pen has some performance penalties.

CustomLineStyles
This property returns a collection of line styles, allowing you to stack multiple line styles on top of each other.
Remarks
Using this collection, you can stack multiple styles on top of each other. When we draw the feature, 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.

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

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