The Properties Mapper allows you to define "Label Icon" and link a custom icon (an .svg in my case) to a distinct value. The icon successfully appears, so I know the mapping has worked. However, the icon appears at full size. I cannot see how to use Properties Mapper to control the size of the icon that appears. Any pointers would be really useful.
Great tool, and thanks in advance for the support.
