I am trying to draw over a figure using tikz, using a method for adding scalebars from this answer. The figures that are drawn over this way have extra padding around them that I can't get rid of. Compare the top row of the image below with the bottom row.

I can kind of workaround it by adding an hskip and manually finding the right number for a give figure (see commented out portion of MWE)

  newcommand{scalebar}[5][white]{%

   noindentbegin{tikzpicture}

    draw (0,0) node[anchor=south west,inner sep=0] (image) { #2 };

    begin{scope}[x={(image.south east)},y={(image.north west)}]

     fill [fill=black, fill opacity=0.5] (0.02,0.1cm) rectangle (#4/#3+0.12,1cm);

     fill [#1] (0.05,0.2cm) rectangle (#4/#3+0.05,0.4cm);

     draw [#1] (0.00,0.4cm) node[anchor=south west, font=footnotesize] {{#4}{#5} };

    end{scope}
