# More random ellipsoids

Generating random ellipsoids with ImageMagick

I thought about this during. Most of the ellipsoids I generate get synthesized outside of the image. Hence I have many blank images like this one

## What can I do?

Not much. I clearly reached the moment where I need to sample and compute these stats using something like Python (or other) and then call ImageMagick from it. See convoluted script below

``````#!/bin/bash

set -x
for I in {1..100}
do
X0=\$((448 + \$RANDOM % 576))
Y0=\$((448 + \$RANDOM % 576))
let "X_CIRCLE_EDGE=\$X0+15"
let "Y_CIRCLE_EDGE=\$Y0+15"
ANGLE=\$((-45 + \$RANDOM % 45))
X_ELLIPSOID_EDGE=\$((\$MIN_RADIUS + \$RANDOM % 75 ))
FLIP_A_COIN=\$((\$((\$RANDOM%10))%2))

if [ \$FLIP_A_COIN -eq 1 ];then
convert -size 1024x1024 xc:black  \
-draw "fill white rotate \$ANGLE ellipse \$X0,\$Y0 \$X_ELLIPSOID_EDGE,\$Y_ELLIPSOID_EDGE 0,360 " \
-draw "fill black rotate \$ANGLE circle \$X0,\$Y0 \$X_CIRCLE_EDGE,\$Y_CIRCLE_EDGE" cell\$I.png
else
convert -size 1024x1024 xc:black  \
-draw "fill white rotate \$ANGLE ellipse \$X0,\$Y0 \$Y_ELLIPSOID_EDGE,\$X_ELLIPSOID_EDGE 0,360 " \
-draw "fill white rotate \$ANGLE circle \$X0,\$Y0 \$X_CIRCLE_EDGE,\$Y_CIRCLE_EDGE" cell\$I.png
fi
done

and the pretty image it produces

\$\$ But why?

Honestly, at this point, it seems like to challenge to work this out on ImageMagick. I know… a dumb challenge.
