Labels with Graphics Layer Renderer?

Permanently deleted user

17. Juni 2015 21:30

I have a workflow that returns a single point on the map. I have the custom SimpleMarkerSymbol figured out, but I would like to add a label or text next to the point with values from a stored variable I have already stored earlier in my workflow. I am adding my custom symbol via the "UpdateGraphicsLayer" renderer.

I've seen examples for points, lines and polygons, but none with text/labels. Can this been done in the 'UpdateGraphicsLayer' tool or do I need to take a different approach?

Thanks!

  I've got the text to appear. Now I'm just working on formatting.

  I did this by creating a string variable called 'textLabel' to concatenate my required variables. Next, with my single point added to a feature set, I used 'UpdateGraphicsLayer' tool. I gave it a new Layer ID, added my existing feature set and used the following renderer string:

  New ESRI.ArcGIS.Client.SimpleRenderer() With { .Symbol = New ESRI.ArcGIS.Client.Symbols.TextSymbol() with {.Text = textLabel  } }

  Here's what the output looks like:

  /customer/servlet/servlet.FileDownload?file=00P6000000eltyXEAQ

  If anyone has suggestions on how to offset the label and format the font, I'd appreciate it.

  Thanks!

  I've got the offset figured out. But I would like to change the font size and make it bold. Any suggestions?

  Here's the renderer string in 'Update Graphics Layer' tool that I am using where textLabel is my concatenated string for the label text.

  New ESRI.ArcGIS.Client.SimpleRenderer() With { .Symbol = New ESRI.ArcGIS.Client.Symbols.TextSymbol() With {.Text = textLabel, .OffsetX = -20, .OffsetY = 5} }

  Thanks!

  Mark,

  This will get you your fontsize, plus fontfamily and foreground.  Still working on Fontstyle which is not a member of TextSymbol class.

   

  New ESRI.ArcGIS.Client.SimpleRenderer() With { .Symbol = New ESRI.ArcGIS.Client.Symbols.TextSymbol() With {.Text = textLabel, .FontSize = 35, .OffsetX = -20, .OffsetY = 5, .FontFamily = New System.Windows.Media.FontFamily("Arial"), .Foreground = New System.Windows.Media.SolidColorBrush(Colors.Red)}}

  Mark,

  Here is the addition of "FontWeight".

  New ESRI.ArcGIS.Client.SimpleRenderer() With { .Symbol = New ESRI.ArcGIS.Client.Symbols.TextSymbol() With {.Text = textLabel, .FontSize = 35, .OffsetX = -20, .OffsetY = 5, .FontFamily = New System.Windows.Media.FontFamily("Arial"), .Foreground = New System.Windows.Media.SolidColorBrush(Colors.Red), .FontWeight = FontWeights.Bold}}

   

  Thanks for posting this thread.

  We will add Rick's example to the list of expression suggestions that Workflow Designer provides for renderers in an upcoming version.

  I found two more renders for FontSyles (Italic) and TextDecorations (UnderLine).

  /customer/servlet/servlet.FileDownload?file=00P6000000elzkyEAA

  New ESRI.ArcGIS.Client.SimpleRenderer() With { .Symbol = New ESRI.ArcGIS.Client.Symbols.TextSymbol() With {.Text = myPoint.X.ToString + " , " + myPoint.Y.ToString, .FontSize = 35, .OffsetX = -20, .OffsetY = 5, .FontFamily = New System.Windows.Media.FontFamily("Arial"), .Foreground = New System.Windows.Media.SolidColorBrush(Colors.Red), .FontWeight = FontWeights.Bold, .FontStyle = FontStyles.Italic, .TextDecorations = TextDecorations.Underline}}

   

  Example renders for FontWeight and FontStyles can be found in the System.Windows Namespace

  .FontWeight = FontWeights.Bold

   

  https://msdn.microsoft.com/en-us/library/system.windows.fontweights(v=vs.110).aspx

  .FontStyle = FontStyles.Italic

   

  https://msdn.microsoft.com/en-us/library/system.windows.fontstyles(v=vs.110).aspx

  Example renders for Textdecorations can be found in the System.Windows.Controls.TextBlock Class, TextBlock Properties

  .TextDecorations = TextDecorations.Underline

   

  https://msdn.microsoft.com/en-us/library/system.windows.controls.textblock.textdecorations(v=vs.110).aspx

   

  Regards,  Rick
