I'm converting ArcGIS Pro SDK to ArcGIS .Net SDK, i have some predefined symbols, which heavily depend on CIMCharacterMarker. I use Pro SDK to export it to json, and then read it in .net SDK using Symbol.FromJson method, create graphic from polyline and this symbol. It display on map, but font family is not correct even when custom font is installed, and runtime type of it's symbol layers is UnknownSymbolLayer, so i cannot change symbol color, size,... at runtime. Why ArcGIS runtime sdk does not support character marker? Are you have any plan to support it in near future?
Below is my symbol with character marker json:
{
"type": "CIMLineSymbol",
"symbolLayers": [
{
"type": "CIMCharacterMarker",
"enable": true,
"anchorPoint": {
"x": -16,
"y": 0
},
"anchorPointUnits": "Absolute",
"dominantSizeAxis3D": "Y",
"size": 20,
"billboardMode3D": "FaceNearPlane",
"markerPlacement": {
"type": "CIMMarkerPlacementAlongLineSameSize",
"placePerPart": true,
"angleToLine": true,
"endings": "NoConstraint",
"offsetAlongLine": 10.5,
"placementTemplate": [
11
]
},
"characterIndex": 76,
"fontFamilyName": "GISPatternFont",
"fontStyleName": "General",
"fontType": "Unspecified",
"scaleX": 1,
"symbol": {
"type": "CIMPolygonSymbol",
"symbolLayers": [
{
"type": "CIMSolidFill",
"enable": true,
"color": {
"type": "CIMRGBColor",
"values": [
0,
0,
0,
100
]
}
}
],
"angleAlignment": "Map"
},
"scaleSymbolsProportionally": true,
"respectFrame": true
}
]
}
And some code to display it:
string file = @"E:\Json\test_character.json";
string json = File.ReadAllText(file);
Symbol symbol = Symbol.FromJson(json);
if (symbol != null)
{
var point1 = new MapPoint(11515202.196315724, 2434684.622706758, SpatialReferences.WebMercator);
var point2 = new MapPoint(11723218.630165813, 2327321.3020099374, SpatialReferences.WebMercator);
var point3 = new MapPoint(11917814.648928799, 2438039.7264785334, SpatialReferences.WebMercator);
var polyline = new Polyline([point1, point2, point3]);
var gr = new Graphic(polyline, symbol);
overlay.Graphics.Add(gr);
}
