I created a figure in Inkscape and exported it to TeX. I used bezier for drawing curves. When I import this to my text, there is a free space between the text and the picture, because some bezier points are out of the picture range. (See negative points in example)
Text
\begin{figure}[htbp]
\centering
\begin{tikzpicture}[y=0.80pt,x=0.80pt,yscale=-1, inner sep=0pt, outer sep=0pt]
\path[draw=black,line join=miter,line cap=butt,line width=0.680pt]
(40,52) -- (40,311) -- (550,311) --
(550,52) -- cycle;
\path[draw=black,dash pattern=on 0.68pt off 0.68pt,line join=miter,line
cap=butt,miter limit=4.00,line width=0.680pt] (274,311) .. controls
(402,-3) and (355,-59) .. (495,311);
\end{tikzpicture}
\end{figure}
Is there a way to shift the whole picture about these negative values and overlap the free space with my text? If I reduce the controls to a positive value, the curves are not useful for me.
