How to set Point Symbol outline colour in UniqueValueRenderer

Question

For a UniqueValueRendererfor point feature layer, I am creating classes using the following :

var uniqueValueClass = new CIMUniqueValueClass
 {
  Values = uniqueValues.ToArray(),
  Label = compValue,
  Visible = true,
  Editable = true,
  Symbol = new CIMSymbolReference { Symbol = GetPointSymbol(symbolIndex, sizeVal,GetColor(colorIndex)) }
 };

and creating the symbols :

private CIMPointSymbol GetPointSymbol(int symbolIndex, int sizeVal,CIMColor colour)
 {
  var shapeDef = GetEsriSymbolTable[symbolIndex];

var cimMarker = SymbolFactory.ConstructMarker(shapeDef.index, shapeDef.font, "Regular", sizeVal, colour); //create   marker from the Font, char index,size,colour
  cimMarker.Rotation = shapeDef.rotation;

var pointSymbol = SymbolFactory.ConstructPointSymbol(cimMarker); //create a symbol from the marker

return pointSymbol;
 }

The colour is being applied to the fill, but not to the shape outline. How can i set the colour for the outline ?

GetEsriSymbolTable(symbolIndex) returns a tuple with font, character index and rotation ]

Is this the only way to create a point symbol and change the outline? Is there any way to actually adjust a CIMPointSymbol outline (not halo)?

For instance, I have:

var symbol = SymbolFactory.Instance.ConstructPointSymbol(ColorFactory.Instance.CreateRGBColor(0,0,0,0), 15);

Basically I want a Point Symbol with a Cyan outline and transparent fill. I can't find how to adjust the outline.

Hi Jack, When you create your CIMMarker, create it as a CIMCharacterMarker. You can then access the "polygon symbol" used to render the marker and then access the SymbolLayers (components that make up the symbol) to change the fill and outline. Here is a code snippet: var cimMarker = SymbolFactory.ConstructMarker(symbolIndex, "Wingdings 3", "Regular", sizeVal, colour) as CIMCharacterMarker; //create marker from the Font, char index,size,colour var polygonMarker = cimMarker.Symbol; //modifying the polygon's outline and fill polygonMarker.SymbolLayers[0] = SymbolFactory.ConstructStroke(ColorFactory.GreenRGB, 2, SimpleLineStyle.Solid); //This is the outline polygonMarker.SymbolLayers[1] = SymbolFactory.ConstructSolidFill(colour); //This is the fill var pointSymbol = SymbolFactory.ConstructPointSymbol(cimMarker); //create a symbol from the marker ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Thanks Uma Harano
