Home plant background on Mosaic

[Domoticatorino]

Hi,
I tried to find out other post in forum without success.

A customer of mine would like to use home plant as background.

I have created my own widget on which I use as background a svg file of home plant. I would like:

- to center the image in the widget.
- reduce the dimensions of the icon (light bulbs and other object).

How can I do that?

Thanks.
