wms layer format in options not used in request

StuartMellanby — Sun, 12 Dec 2021 07:19:00 GMT

Should the options parameter image format work as I have below? When you set the value for image format by wmsLayer.setImageFormat('svg') it works, but via options.format it's ignored?

Any thoughts? I'm after a gif 🙂 all I can get is svg or png? Does setting a background colour still require you use a custom wms layer like http://help.arcgis.com/en/webapi/javascript/arcgis/help/jssamples/layers_custom_wms.html
