ThinkGeo.MapSuite.SilverlightCore.PointStyle

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.

This class allows you to define how points are drawn on the canvas.

Members Summary

Public Constructors

PointStyle()

This is a constructor for the class.

Remarks

If you use this constructor, you should set the various properties manually. Specifically, you will want to set the PointType, which allows you to choose between bitmap, character and symbol as an option for displaying your points.

Parameters

PointStyle(GeoImage)

This is a constructor for the class.

Remarks

If you use this constructor, the PointStyle will be set to Bitmap.

Parameters

PointStyle(GeoFont,Int32,GeoSolidBrush)

This is a constructor for the class.

Remarks

If you use this constructor, the PointStyle will be set to Character.

Parameters

PointStyle(PointSymbolType,GeoSolidBrush,Int32)

This is a constructor for the class.

Remarks

If you use this constructor, the PointStyle will be set to Symbol.

Parameters

PointStyle(PointSymbolType,GeoSolidBrush,GeoPen,Int32)

This is a constructor for the class.

Remarks

If you use this constructor, the PointStyle will be set to Symbol.

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.

Public Properties

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.

Return Value

YOffsetInPixel

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

Remarks

This property allows you to specify a Y offset. When combined with an X 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.

Return Value

CustomPointStyles

This property returns a collection of area styles allowing you to stack multiple area 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.

Return Value

PointType

This property gets and sets the type of point you want to draw.

Remarks

When using the PointStyle you choose between a bitmap, a font or a predefined symbol to represent the point. Each of these options has corresponding properties on the point symbol. If you set the type to character, then you need to set the properties that start with “Character,” such as “CharacterFont.” The same is true for the symbol.

Return Value

RotationAngle

This property gets and sets the angle of rotation for the drawing of the point.

Remarks

This property controls the rotation of the bitmap, character or symbol, depending on the PointType.

Return Value

Image

This property gets and sets the image used if the PointType property is Bitmap.

Remarks

This property is where you can set the image for the points if the PointType is Bitmap. It uses a GeoImage, so you can either reference a file or supply a stream.

Return Value

ImageScale

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

Remarks

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.

Return Value

CharacterFont

This property gets and sets the font that is used for the character if the PointType is Character.

Remarks

This property allows you to set the font from which to select a character index if you choose the Character PointType.

Return Value

CharacterIndex

This property gets and sets the index position of the character you want to use from the font you selected in the CharacterFont property.

Remarks

You need to specify the index position of the character you want to use from the font you selected. For example, if you choose 1, then we will use the first character in the font you set in the CharacterFont property.

Return Value

CharacterWpfGeoBrush

This property gets and sets the SolidBrush used to color the font character for the point.

Remarks

This brush is used to draw the character. It is only used if the PointType is Character. If you need a brush other than the SolidBrush, you should look in the advanced property of the class.

Return Value

SymbolType

This property gets and sets the type of symbol you want to use if the PointType is Symbol.

Remarks

You can choose between a number of predefined symbols. The symbols are simple geometric objects that are typically used for abstract representations on a map. If there is a specific symbol you need that is not part of our symbol collection, you can submit it to us and we will consider adding it.

Return Value

SymbolWpfGeoBrush

This property gets and sets the SolidBrush used to color the interior of the Symbol.

Remarks

This brush is used to draw the interior of the symbol. It is only used if the PointType is Symbol. If you need a brush other than the SolidBrush, you should look in the advanced property of the class.

Return Value

SymbolPen

This property gets and sets the SolidBrush used to draw the oultine of the Symbol.

Remarks

This pen is used to draw the outline of the Symbol. By default the pen draws a transparent (invisible) color, which just leaves you with a fill.

Return Value

SymbolSize

This property gets and sets the size of the symbol if the PointType is Symbol.

Remarks

The allows you to make the symbol larger and smaller.

Return Value

Advanced

This property gets the advanced properties of the PointStyle.

Remarks

This allows you to set the advanced properties of the style.
