Howdy, I have an image field that allows for one image. I want the preview in the panel to have a white background. I’m assuming if a upload a transparent PNG the background will be white (not that checkboard pattern).
My blueprint:
logo:
label: Logo
type: files
multiple: false
layout: cards
image:
back: white
Don’t upload PNGs. Their transparent background sometimes is not correct in the thumbs, e.g. in the panel!
May be this is better if you change the driver to “im”.
I have used transparent PNG images on many many websites using GD as the driver (which is the default) without any issue whatsoever, either with the thumb itself or the white/back back showing through.
