Hi All,
Recently i develop a gis app with Navtive Maps SDK 200.1, i want to apply a raster function(Raster_calculator_function) on a raster file, but it doesn't work, so i wander whether i can use the function:"Con()" in the expression statement as following:
string theJSON_String =
@"{
""raster_function_arguments"":
{
""expression"":{ ""string"":""Con(r1>r2,0,1)"",""name"":""expression"",""type"":""Raster_function_variable""},
""raster_names"":{ ""name"":""raster_names"",""type"":""Raster_function_variable""},
""raster_names"":{ ""name"":""raster_names"",""string_array"":[""r1"",""r2""],""type"":""Raster_function_variable""},
""r1"":{ ""name"":""r1"",""is_raster"":true,""type"":""Raster_function_variable""},
""r2"":{ ""name"":""r2"",""is_raster"":true,""type"":""Raster_function_variable""},
""type"":""Raster_function_arguments""
},
""raster_function"":{ ""type"":""Raster_calculator_function""},
""type"":""Raster_function_template""
}";
// Create a raster function from the JSON string using the static/Shared method called: RasterFunction.FromJson(json as String)
RasterFunction myRasterFunction = RasterFunction.FromJson(theJSON_String);
Esri.ArcGISRuntime.Rasters.RasterFunction(path as String)
// Get the raster function arguments
RasterFunctionArguments myRasterFunctionArguments = myRasterFunction.Arguments;
// Get the list of names from the raster function arguments
IReadOnlyList<string> myRasterNames = myRasterFunctionArguments.GetRasterNames();
// Apply the first raster name and image service raster in the raster function arguments
myRasterFunctionArguments.SetRaster(myRasterNames[0], raster1);
myRasterFunctionArguments.SetRaster(myRasterNames[1], raster2);
var layer = new RasterLayer(new Raster(myRasterFunction));
