Property descriptions

RectShape.BorderColor

BorderColor As Color

The color of the object's border.

RectShape.BorderOpacity

BorderOpacity As Double

Indicates the level of opacity.

Degrees of transparency is currently supported only on macOS and Windows. On other platforms, the border is either visible (100%) or invisible.

The following code adds a border to a RectShape:

Var a As New RectShape
a.BorderOpacity = 100
g.DrawObject(a)

RectShape.BorderWidth

BorderWidth As Double

The width of the border, in points. The default is 1.

The width a Double value with a default of 1.0.

RectShape.FillColor

FillColor As Color

The color of the interior of the shape.

RectShape.FillOpacity

FillOpacity As Double

The opacity of the interior, from 0 (completely transparent) to 100 (opaque).

This example sets the Fill to 50% opacity.

Var a As New RectShape
a.BorderOpacity = 100
a.BorderColor = Color.Black
a.BorderWidth = 2.75
a.FillOpacity = 50
a.FillColor = Color.Red
g.DrawObject(a)

RectShape.Height

Height As Double

The height of the rectangle.

This example sets the height and width of the shape to 150 pixels.

Var r As New RectShape
r.Width = 150
r.Height = 150
r.Border = 100
r.BorderColor = Color.Black
r.FillColor = Color.Teal
r.BorderWidth = 2.5
r.Rotation = -0.78
g.DrawObject(r)

RectShape.Rotation

Rotation As Double

Clockwise rotation, in radians, around the X, Y point. Only set the rotation after you have drawn all your objects.

This code rotates the RectShape 0.9 radians.

Var a As New RectShape
a.Height = 150
a.Width = 150
a.Rotation = 0.90
g.DrawObject(a)

RectShape.Scale

Scale As Double

The scaling factor relative to the object's original size.

The following code rescales the RectShape by a factor of 1.5.

Var a As New RectShape
a.Scale = 1.5
g.DrawObject(a)

RectShape.Width

Width As Double

The width of the rectangle.

This example sets the Width to 150 pixels.

Var r As New RectShape
r.Width = 150
r.Height = 150
r.Border = 100
r.BorderColor =Color.Black
r.FillColor =Color.Teal
r.BorderWidth = 2.5
r.Rotation = -0.78
g.DrawObject(r)

RectShape.X

X As Double

The horizontal position of the center or main anchor point.

This example sets the horizontal position to 100 pixels from the left of the containing Canvas.

Var a As New RectShape
a.Height = 150
a.Width = 150
a.X = 100
g.DrawObject(a)

RectShape.Y

Y As Double

The vertical position (down from top) position of the center or anchor point.

This example moves the position of the RectShape down 100 pixels from the top of the containing Canvas.

Var a As New RectShape
a.Height = 150
a.Width = 150
a.Y = 100
g.DrawObject(a)

Method descriptions

RectShape.Contains

Contains(X As Double, Y As Double) As Boolean

Tests whether the object contains the point X, Y. Returns True if the rectangle contains the point specified by X, Y.

This code tests whether the RectShape contains the passed point:

Var r As New RectShape
r.Width = 75
r.Height = 75
r.Border = 100
r.Bordercolor =Color.Black
r.FillColor =Color.Teal
r.BorderWidth = 2.5
r.Rotation = -0.78
If r.Contains(50, 50) Then
  ' draw something here..
End If
g.DrawObject(r)

Sample code

The following code in the Canvas.Paint event handler draws a diamond shaped rectangle:

Var r As New RectShape
r.Width = 75
r.Height = 75
r.BorderOpacity = 100
r.BorderColor =Color.Black
r.FillColor =Color.Teal
r.BorderWidth = 2.5
r.Rotation = -0.78
g.DrawObject(r)
