I need to transform a square image in circle image with [MiniMagick](https://github.com/minimagick/minimagick).

I know there is a [way](https://stackoverflow.com/questions/9026935/imagemagick-crop-square-from-circle) with `ImageMagick`:

```
convert -size 300x300 xc:transparent -fill "image.png" -draw "circle 240,90 290,90" -crop 100x100+190+40 +repage circle1.png

```

I've tried to translate :

```
img.combine_options do |c|
  c.draw "circle 240,90 290,90"
  c.crop "100x100+190+40"
  c.repage.+
end

```

I get this stuff, a black circle with my big nose as background image :

if anyone know how to translate this properly... please !!
