MapSpecification.Polygons Property

An array of Polygon objects to render. Optional.

Public Polygons As Polygon[]

[C#]
public Polygon[] Polygons;

Example

[Visual Basic]

'Create an array of Polygon objects. For each Polygon object,
'set the DataSourceName, EntityID, BorderColor, and FillColor properties.
Dim fillColor As New ElementColor
fillColor.A = Convert.ToByte(txtFillAlpha.Text)
fillColor.B = Convert.ToByte(txtFillBlue.Text)
fillColor.G = Convert.ToByte(txtFillGreen.Text)
fillColor.R = Convert.ToByte(txtFillRed.Text)

Dim lineColor As New ElementColor
lineColor.A = Convert.ToByte(txtLineAlpha.Text)
lineColor.B = Convert.ToByte(txtLineBlue.Text)
lineColor.G = Convert.ToByte(txtLineGreen.Text)
lineColor.R = Convert.ToByte(txtLineRed.Text)

Dim poly As New Polygon
poly.DataSourceName = "MyDataSource"
poly.EntityID = "MyEntityID"
poly.BorderColor = lineColor
poly.FillColor = fillColor

' Set the MapSpecification.Polygons property to the polygon array.
spec.Polygons(1) = New Polygon
spec.Polygons(0) = poly

'Call the RenderServiceSoap.GetMap method.
Dim mi() As New MapImage
mi = render.GetMap(spec)
pictMap.Image = New Bitmap(New System.IO.MemoryStream(mi(0).MimeData.Bits))
