  • Article

This article is about Shapes object in Microsoft Small Basic programming language.

Type of Shapes

There are following 5 types of Shapes.

  • Ellipse
  • Image
  • Line
  • Rectangle
  • Triangle

Special Features

Comparing to GraphicsWindow.DrawXXX or GraphicsWindow.FillXXX, Shapes object has following six special features.

  • Movable
  • Rotatable
  • Zoomable
  • Can Be Transparent
  • Hidable
  • Removable

Movable

There are two operations to move a shape - Shapes.Animate() and Shapes.Move().

GraphicsWindow.BrushColor = "Cyan"
GraphicsWindow.PenWidth = 4
GraphicsWindow.PenColor = "DarkCyan"
shp = Shapes.AddRectangle(200, 100)
Shapes.Animate(shp, 200,  200, 2000)
Program.Delay(2000)
Shapes.Move(shp, 300,  200)

Rotatable

A shape is rotatable with Shapes.Rotate() operation.

Shapes.Rotate(shp, 45)

Zoomable

A shape is zoomable with Shapes.Zoom() operation.

For scale =  0.1 To 2 Step 0.1
  Shapes.Zoom(shp, scale,  scale)
  Program.Delay(500)
EndFor

Can Be Transparent

A shape can be transparent with Shapes.SetOpacity() operation.

For opacity =  100 To 10 Step -10
  Shapes.SetOpacity(shp, opacity)
  Program.Delay(500)
EndFor

Hidable

A shape is hidable with Shapes.HideShape() operation.  And also be shown with Shapes.ShowShape() operation.

Shapes.HideShape(shp)
Program.Delay(1000)
Shapes.ShowShape(shp)
Program.Delay(1000)

Removable

A shape is removable with Shapes.Remove() operation.

Shapes.Remove(shp)
