Dimension2

Many values in a Shape Sheet define a 2D Point, and rather than define the X and Y values in separate expressions, Fizzy uses one expression.

This makes many tasks simpler, for example, the center of a shape is given by the expression

Size / 2

The most verbose way e.g. :

Dimension2( 1mm, 2mm )

However, you can also simply use :

( 1mm, 2mm )

It is possible to leave the brackets off too, but that isn't recommended (for clarity).

The units do not have to be the same. e.g.

(10mm, 2 pt)

The X and Y values don't have to be constants. e.g. :

(Size.X / 2, Size.Y / 4)

Mathematical operators work as you might expect :

Left	Operator	Right	=
Dimension2	+ or -	Dimension2	Dimension2
Dimension2	* or /	Double	Dimension2
Dimension2	* or /	Vector2	Dimension2
Dimension2	/	Dimension2	Vector2

Name	Type	Comments
X	Dimension
Y	Dimension
Length	Dimension
Angle	Angle	The angle of this point from the origin.

Name	Parameters	Return Type	Comments

rotate	Angle	Dimension2
toString	none	String
format	String	String	Uses Java's DecimalFormat
toUnits	Units	Dimension2	Converts to different units.
clamp	min : Dimension2, max : Dimension2	Dimension2
min	other : Dimension2	Dimension2	Dimension2(min( this.X, other.X) , min ( this.y, other.Y))
max	other : Dimension2	Dimension2
