Graph IDE ► Basic Graphics ► Rectangle

A rectangle is defined as four points at the intersection of two horizontal and two vertical lines. It can be transformed into a parallelogram by a linear transformation, such as a rotation and then flattening. It also has associated attributes, such as corner radii, so it can be an oval, and other graphic attributes. The figure below shows some examples of a rectangle.

Some standard operations are itemized below.

• To create a rectangle bring forward the Graphic Selector, select the rectangle factory cell and then mouse down on a Graphic View and drag the cursor to another point. The initial and final cursor locations define the boundary of a rectangle. If the width and height are the same then it is a square. Prototypes can also be dragged out from the rectangle Factory Inspector.

• You can also create rectangles from the standard Palettes ► Basics ► Squares menu item.

• Rotating and resizing the rectangle transforms it to a parallelogram. For more information see Standard Editing.

• To program a rectangle see the Programming section.

Menu Shortcuts

Menu shortcuts are common to all graphics and are described in the Graphics section.

Oval Parameters

Corner Radius : Shows and defines the radius of each corner of the rectangle. When the corner radius is non-zero then the rectangle is an oval. If the rectangle is resized without maintaining aspect then the oval becomes a general affine transformed oval.

Normal Form

Reset To Normal Form : Select this to set the width and height of the rectangle to the reference frame of the graphic.
