Metapost-icon.svg
This vector image was created with MetaPost.

This SVG was created by running the following commands:

mpost fig.mp
ps2pdf -dEPSCrop fig.1 fig.pdf
pstoedit -page 1 -dt -xscale 2 -yscale 2 -f sk fig.pdf fig.sk
inkscape -z --vacuum-defs -f fig.sk -l fig.svg

where fig.mp is a file containing the following MetaPost program:

prologues := 3;
input boxes

beginfig(1);
pickup pencircle scaled 2pt;

numeric polyscale, textscale;
polyscale := .8;
textscale := 2;
dotlabeldiam := 6bp;    % dots twice normal size

% Vertices, based on the oritinal bitmap version.
z0 = polyscale*(280, 170);
z1 = polyscale*(58, 65);
z2 = polyscale*(398, 44);
z3 = polyscale*(387, 114);
z4 = polyscale*(350, 102);

% Position of label in middle.
z5 = polyscale*(240, 105);

path poly;
poly = z0--z1--z2--z3--z4--cycle;
fill poly withcolor 0.85white;
draw poly;

label(btex$ n = 5 $etex scaled textscale, z5);

dotlabel.top(btex$ x_0, y_0 = x_5, y_5 $etex scaled textscale, z0);
