Rectangle
Rectangle[{xmin,ymin},{xmax,ymax}]
represents an axis-aligned filled rectangle from {xmin,ymin} to {xmax,ymax}.
Rectangle[{xmin,ymin}]
corresponds to a unit square with its bottom-left corner at {xmin,ymin}.
Details and Options

- Rectangle can be used as a geometric region and a graphics primitive.
- Rectangle represents the region
.
- Rectangle[] is equivalent to Rectangle[{0,0}]. »
- CanonicalizePolygon can be used to convert a rectangle to an explicit Polygon object.
- Rectangle can be used in Graphics.
- In graphics, the points {xi,yi} can be Scaled, Offset, ImageScaled, and Dynamic expressions.
- The option RoundingRadius->r can be used to specify rounded corners rendered using circles of radius r.
- Graphics rendering is affected by directives such as FaceForm, EdgeForm and color.
