Bug: TextSymbol background transparency value can't be set opaque (v4.26)

BryanMc — Wed, 15 Mar 2023 20:21:38 GMT

When setting the textSymbol backgroundColor property with RGBA, the alpha channel will not properly show fully opaque values (alpha = 1) when using RGBA array. The background always has some transparency remaining. Lowering the alpha channel (0.5 or 0.25, etc) does seem to work as expected.

A codepen example using the current 4.26 version of the API is attached. The alpha is set to 1, but the the map can still be seen behind the label background: TextSymbol Background transparency (codepen.io).

I could be missing something, but thinking this is likely a bug.

Hi @BryanMc - I cannot reproduce the issue you are describing. I don't see transparency in the codepen you shared, as shown in the image below. If you are seeing something different than the screenshot below, please share some information about your browser / OS / graphics card and we can investigate further. Thanks!

Hi @AnneFitz ,

If I look very closely at your image, I can see some of the "York" text in the New York basemap label behind the textSymbol still. Much easier to see on my png below from the same:

Hi @AnneFitz , I was just wondering if there might be any updates on a fix for this? Thank you so much for the support.

Hi Bryan -- we've installed a fix for the upcoming release (4.27). You can test it out using the development version of the API by updating the CDN to https://js.arcgis.com/next. Let me know if you are still running into any issues!

Thank you Anne. I tested the CDN next and it appears to be working. Looking forward to the rollout fix in 4.27.
