Replacing an CIMPictureMarker color with an attribute

ChaosSteve — Tue, 24 Dec 2024 14:41:40 GMT

I am looking to do a feature layer which I have set up with a renderer with a CIM Symbol. I want to change the color of theCIMPictureMarker based on an attribute of the feature. My current code doesnt let me change the color. Is this the best renderer to use? I did not use a unique value renderer since I dont need to compare the value I want to use. I am also curious if I can rework valueExpressionInfo to call a function.

Thanks in advance

{
    type: "simple",
        symbol: new CIMSymbol({
        data: {
            type: 'CIMSymbolReference',
            primitiveOverrides: [
                {
                    type: 'CIMPrimitiveOverride',
                    primitiveName: 'imageMarker',
                    propertyName: 'replacementColor',
                    valueExpressionInfo: {
                        type: 'CIMExpressionInfo',
                        expression: '$feature.statusColor',
                        returnType: 'Default',
                    },
                }
            ],
            symbol: {
                type: 'CIMPointSymbol',
                primativeName: "imageMarker",
                symbolLayers: [
                    {
                        type: "CIMPictureMarker",
                        enable: true,
                        size: 20,
                        scaleX: 1,

colorSubstitutions: [
    {
        targetColor: [255, 0, 0, 255], // red
        replacementColor: [0, 0, 255, 255] // blue
    }
]

Hi! Based on your code snippet above, it looks like you have a color stored as the attribute value. Instead of overriding the colorSubstitution value (which is not supported), try overriding the CIMPictureMarker tintColor property. Here's an example: https://codepen.io/annefitz/pen/wBwrooy

Note that the primitiveName on the override must match the primitiveName on the symbol layer with the property you are trying to override.
