I have a black and white graphic of some trees. The trees are black and the background is white. I need to make the background transparent.

Any suggestions?

convert image -transparent white result.png (any suffix such as gif, tiff that supports transparency --- Note jpg does not support transparency)

see http://www.imagemagick.org/Usage/color_basics/#replace

I suggest as a beginner that you might study
