I often create pictures in tikz that I want to either send to someone, or include in an email. The problem with that is that there is a big white space around and and especially below my pictures.
To get around this, I usually print screen my figure and crop it to get the size I want. Another solution is to use beamer and then scaling to make the figure as big as the slide size. Those two solutions, though, are not all that good. What I would really like is a way to get the pdf file to be just as big as my picture, as if it was cropped from start.
Is there a package to do that?
