@tomasz-rekawek-tb Thanks for the report!

Just curious if you could post one of the png images here so I can test it locally on my machine. At the same time, please let me know what version of node you're currently using and i'll do my best to re-create the issue.

I haven't used this module in a few years but I'd be happy to investigate and see if we can figure out what's going wrong!

This happens in the case when the PNG image is entirely in black (rgba(0, 0, 0, 255)).

This shows an empty SVG (black color):

This shows the correct SVG (grey color):

I tested on an older version of Node.js. The version doesn't seem to matter (although I might be wrong).

By the way, thanks for creating this package!
