I am trying to setup a dashboard with a CSS coloured background and a overlaid image/logo (using the template node), and I want to apply opacity to the image/logo without effecting anything else.
To get this working, it seems that I need to modify the SVG code to include opacity for the each fill section (which is fine and I can do), and I can't use the original image/logo URL.
The ui_svg_graphics node is able to accept raw svg code, which is really nice because the image/logo information is stored within the flow and the colours/opacity can be modified directly.
Is it possible to insert raw svg code into the template node CSS to display as a background image, instead of having to refer to a URL or image file stored locally (which also requires the NodeRED settings to be manually updated)?
Many thanks in advance.
