Export with transparency PNG files

Hello,

I am a big user of Librecad which I love.
I am facing an issue. I would like to export my drawings over a transparent background.

So i Go export PNG ... but it seems to only include a white or black backround, i need a transparent background.

Any solution ? Thanks a lot !

Not possible in LibreCAD.
You have to turn the colour white or black to transparent in an external graphics program like Gimp.
