	printErrorFatal("Unable to load font", err)
	}

--font.file option could not help for png format output.Seems embed font file has no effect for github.com/kanrichan/resvg-go .

I am having the same problem -- using the linux build of freeze from inside wsl2 on windows 11 -- trying to specify font.family as "Source Code Pro", or setting font.file as the path to the "SourceCodePro-Regular.ttf" file in my windows\fonts directory. Either way, I get a blank .PNG file. If I use "JetBrains Mono" for the font.family, the file renders correctly (but with an undesirable font).

Same for me in Ubuntu 22.04

I'm getting this on mac as well. It looks like the font config is not actually considered on this line:

freeze/png.go

Line 50 in 578e9d0

err = fontdb.LoadFontData(font.JetBrainsMonoTTF)

I've had a quick play to see if I can hard code another font file but its not working. Must be more at play here. I'll make do with default font for now as I don't have more time

Came here to say I’m having the same issue:

freeze css.css -t dracula --font.family 'Sarasa Term J Nerd Font' --font.size 16 -o css.png

This just outputs a PNG file with a background but no text.
