Background is mandatory? Transparent backgrounds not possible?

[holtkamp]

When looking at the source code, it seems that a background is always added.

When looking on how to set a 'transparent' color as background color, I got stuck. It seems the Gray, Rgb and Cmyk do not support transparancy / alpha channel?

@DASPRiD I have had quite a few users ask about this down stream as well. I looked over #10 and I agree that the background color should be white by default. If I go ahead and make a pull request with the requested change, can we get this merged in?

Thanks :)

I guess so. I'd say that we could alternatively offer RGBA as a color (at least for the outputs, which supports it. I'm not sure whether CMYKA would make any sense, would have to think about that.

RGBA sounds like a better approach. EPS, PNG, would be able to support alpha channels. SVG may be able to through the use of fill-opacity?

[DASPRiD]

SVG supports style="fill: rgba();" just fine.

But as said, Gray and CMYK would have to allow alpha channels as well for consistency.
