So you want a super slick inner glow effect for some polygons in your app, to no avail. Sure, an “inner glow” effect isn’t yet supported in the JavaScript API, nor is a buffer fill. But Picture strokes are supported, and you can bake all manner of visual shenanigans into those things…
- Here is the CodePen where you can check it out and play with the parameters.
- Here’s the blue glow graphic.
- And here’s a version in red.
You can use these graphics as picture fills in ArcGIS Pro, as well. Here are some examples…


Thanks to Anne Fitz for the collaboration, and setting up the CodePen!
Happy inner-glowing!
Your article seems to be lacking some detail. The app, do you mean a self hosted app on enterprise or can this be an AGOL web app? In ArcPro, are you just importing a picture as a symbol? A few step-by-steps would be awesome. Thanks!
Thank you! Using ArcGIS Pro I wanted to produce an inner glow on the ocean along the shore (e.g. Ocean polygon 1:110m from NE). This worked out fine … until i decided to switch to Robinson projection: now I get a glow as well on ocean’s horizon (in my case date-line) left and right “edge”, where no feature is found. The solution was found in four simple steps: 1.) Use Land-area in stead of ocean –> now i need to have an OUTER glow on land to reproduce the inner-glow effect on the ocean along the shore 2.) select inner-glow.png… Read more »
